'''Arthur Stanley Wohlmann''' (1867–1943), also known as '''Arthur Stanley Herbert''', was an English [[physician]] and [[Balneotherapy|balneologist]], known for his significant contributions to the therapeutic use of the [[spa]] in [[New Zealand]]. Born in London, he qualified as a dentist in 1894 and moved to New Zealand in 1902. Wohlmann was appointed as the first government balneologist in Rotorua, where he played a pivotal role in developing the town into a renowned spa destination.

His work included the design and supervision of various therapeutic facilities, promoting the health benefits of the [[spa]]. Wohlmann's efforts were instrumental in attracting both local and international visitors to Rotorua, boosting its reputation and economy. He also published extensively on the therapeutic properties of hot springs, contributing valuable knowledge to the field of [[Balneotherapy|balneology]].

Wohlmann's influence extended beyond Rotorua as he consulted on similar projects in other regions. He retired in 1935 but continued to be involved in balneology until his death in 1943. His legacy is marked by his dedication to advancing the scientific and therapeutic use of geothermal resources.

== Biography ==
Trained in London and having practiced [[balneotherapy]] for several years in the renowned spa town of [[Bath, Somerset|Bath]], he was chosen in 1902 by the government of New Zealand, shortly after that country had been the first to set up a government tourism agency, to be the colony's official [[balneologist]]. This title, which at first aroused astonishment, reflected the economic importance attributed to the development of New Zealand spa tourism and the hope of attracting an influx of international curists, drawn by the beauty and virtues of the [[North Island]]'s thermal zone.<ref name=":19" /><ref name=":20">{{Cite journal |last=Johnson |first=Ralph |year=1990 |title=Arthur Stanley Wohlmann, the first government balneologist in New Zealand |journal=Medical History |volume=34 |issue=10 |pages=114–126|doi=10.1017/s0025727300071039 |pmid=11622587 |pmc=2557447 }}</ref>

Wohlmann enthusiastically took on the task of surveying the springs and promoting them, notably by producing brochures and exhibitions. His priority, however, was the development of the [[Rotorua]] site, where he aimed to build an international [[spa]]. The latter, inaugurated in 1908, boasts a level of luxury and equipment unrivaled in the southern hemisphere. Although the site is still world-famous today, this major investment did not bear the fruit hoped for at the time. This was mainly due to the remoteness of the country and despite the innovations introduced by Wohlmann, including a dangerous radioactive cure. It eventually fell into disrepair, eaten away by sulfurous fumes.<ref name=":20" />

Despite some of the errors typical of the medical concepts of the time, Wohlmann brought a scientific and holistic approach to the practice of thermalism, the latter being particularly in tune with the government's tourist propaganda, thanks to the importance attached to a change of scenery.<ref name=":20" />

== Context ==
In the 19th century, the development of tourism was closely linked to that of the [[spa]]. During the period, most European countries and the United States experienced the "spa fever", with the expansion or launch of spas and their provision of prestigious tourist facilities to satisfy the growing demand for [[hydrotherapy]] cures and [[mineral water]] consumption.<ref>{{Cite book |last=Mackaman |first=Douglas |title=Leisure Settings : Bourgeois Culture, Medicine, and the Spa in Modern France |publisher=University of Chicago Press |year=1998 |language=}}</ref><ref>{{Cite news |last=Grabar |first=Henry |date=2015 |title=Selling Water: How Hot Springs Became a 19th-Century American Tourist Attraction |url=https://www.theatlantic.com/business/archive/2015/11/hot-springs-19th-century-tourism/417618/ |work=The Atlantic |language=}}</ref><ref>{{Cite book |last=Penez |first=Jérôme |title=Histoire du thermalisme en France au xixe siècle : Eau, médecine et loisirs |publisher=Economica |year=2004 |language=fr}}</ref>

In 1874, [[William Fox (politician)|William Fox]] recommended that the [[New Zealand Government]] follow the American example of [[Yellowstone National Park]], created in 1872, and intervene to protect the spa areas of the [[North Island]].<ref>{{Harvtxt|McClure|2004|p=11}}</ref> He suggested the creation in this region of "a sanatorium not only for the Australian colonies but also for India and other parts of the globe".<ref>{{Cite web |title=Exploiting hot springs |url=https://archive.wikiwix.com/cache/index2.php?url=https%3A%2F%2Fteara.govt.nz%2Fen%2Fdocument%2F6447%2Fexploiting-hot-springs#federation=archive.wikiwix.com&tab=url |website=Te Ara, The Encyclopedia of New Zealand}}</ref> The project began to be implemented in 1881 with the passing of the ''Thermal-Springs Districts Act,'' which gave the Crown the right to purchase land offered for sale in the area.<ref>{{Harvtxt|McClure|2004|p=14}}</ref> In 1886, a small private [[sanatorium]] was opened in [[Rotorua]].

Balneology was introduced into the New Zealand political landscape in 1897. In October, during parliamentary debates on the budget, the allocation of a £1,000 line for the annual salary and expenses of a balneologist – a large sum reflecting the national importance of the function – was denounced by the opposition as a "gross extravagance".<ref name=":0" /><ref>{{Cite journal |title=MR T. E. Taylor Before His Constituents |url=https://paperspast.natlib.govt.nz/newspapers/TS18980209.2.20 |journal=The Star}}</ref> It attracted criticism from some of the press: while the ''Otago Witness'' assumed that the term referred to the North Island's hot springs,<ref>{{Cite journal |title=Notes and Queries |url=https://paperspast.natlib.govt.nz/newspapers/OW18971223.2.117 |journal=Otago Witness}}</ref> the ''Ohinemuri Gazette'' suggested that the role of a balneologist would be to show patients how to locate whales in the warm waters of Lake [[Rotorua]];<ref>{{Cite journal |title=Passing Notes |url=https://paperspast.natlib.govt.nz/newspapers/OG18960815.2.17 |journal=Ohinemuri Gazette}}</ref> the ''Daily Telegraph'' regarded the choice of the term as a form of offensiveness designed to conceal the nature of the tasks involved;<ref>{{Cite journal |title=At Home and Abroad |url=https://paperspast.natlib.govt.nz/newspapers/DTN18971118.2.5 |journal=Daily Telegraph}}</ref> and the ''Observer'' suggested that, as the necessary "expertise" seemed easy to acquire, the post could easily be awarded to a local resident.<ref>{{Cite journal |title=A Quill for Everyone |url=https://paperspast.natlib.govt.nz/newspapers/TO18960808.2.16 |journal=The Observer}}</ref>

By 1898, Reeves met Dr. Karl Grube, head physician at the [[Bad Neuenahr-Ahrweiler|Bad Neuenahr]] spa clinic and known for his "young, energetic personality, extensive experience of thermal springs and thorough knowledge of the subject". He was fluent in English and treated celebrities such as the Prince of Fürstenberg and the [[Princess Mary Adelaide of Cambridge|Duchess of Teck]], who he hoped would tempt them to come and experience the thermal benefits of New Zealand.<ref>{{Cite journal |title=The Government Balneologist |url=https://paperspast.natlib.govt.nz/newspapers/LT18980611.2.12 |journal=Lyttelton Times}}</ref><ref name=":20" /> However, Grube requested, in addition to the £800 annual salary he had been offered, the right to charge for private consultations, which the government refused.<ref>{{Cite journal |title=New Zealand Parliamentary Debates |url=https://babel.hathitrust.org/cgi/pt?id=uc1.32106019788105&view=1up&seq=385 |journal=Wellington |volume=108 |pages=361}}</ref>

[[File:Appointment of balneologist for Rotorua.jpg|thumb|Announcement of Wohlmann's nomination.]]
In March 1902, several New Zealand newspapers announced the nomination of Arthur Stanley Wohlmann to the post of government balneologist, often mentioning a decisive fact: despite his Teutonic-sounding name,<ref>{{Cite journal |date=1902 |title=Local Gossip |url=https://paperspast.natlib.govt.nz/newspapers/NZH19020329.2.57.2 |journal=New Zealand Herald}}</ref> he came from a family that had been "English for two hundred years".<ref>{{Cite journal |date=1902 |title=Appointment of Balneologist for Rotorua |url=https://paperspast.natlib.govt.nz/newspapers/NZH19020321.2.31 |journal=New Zealand Herald}}</ref>

Born on March 3, 1867, in [[Hertford]], where he attended secondary school, Wohlmann began his medical studies in 1885 at [[Guy's Hospital]] in London, graduating in 1892.<ref name=":1">{{Cite journal |date=1944 |title=Obituary |journal=British Medical Journal |volume=1 |issue=4341}}</ref> After practicing in the city, he spent four months as a surgeon at the British hospital in [[Port Said|Port Saïd]], then spent two years as a resident physician at the [[Royal Mineral Water Hospital]] in [[Bath, Somerset|Bath]], where he treated rheumatoid arthritis,<ref>{{Cite journal |last=Beaufort |first=Anthony |title=Analysis of 100 Cases of Rheumatoid Arthritis Treated in the Royal Mineral Water Hospital, Bath |journal=British Medical Journal |date=1896 |volume=1 |issue=1838 |pages=723–724 |doi=10.1136/bmj.1.1838.723|pmid=20756106 |pmc=2406472 }}</ref> before setting up his practice in the city renowned for its spa treatments.

Shortly after arriving in New Zealand in July 1902 and establishing his residence in Rotorua, Wohlmann undertook inspection visits to the colony's thermal springs, in particular those at [[Waiotapu]], [[Wairakei]], Orakei Korako, [[Taupō]], [[Tokaanu]], Okoroire, [[Te Aroha]], [[Helensville]], Morere and Hanmer,<ref name=":4">{{Cite journal |last=Wohlmann |first=Arthur |date=1903 |title=Second Annual Report |url=https://paperspast.natlib.govt.nz/parliamentary/AJHR1903-I.2.3.2.2 |journal=Department of Tourist and Health Resorts }}</ref> taking water samples which he had analyzed by the [[Colonial Museum]] laboratory in [[Wellington]],<ref name=":5">{{Cite journal |last=Hodder |first=Peter |date=2014 |title=Wohlmann's waters and the Colonial Laboratory |url=https://nzic.org.nz/unsecure_files/cinz/2014-78-4.pdf |journal=Chemistry in New Zealand |volume=78 |issue=4}}</ref> to select the sites he recommended for development.<ref>{{Cite journal |date=1904 |title=New Zealand Health Resorts |url=https://paperspast.natlib.govt.nz/newspapers/NZH19040227.2.17 |journal=New Zealand Herald}}</ref>

In the report he submitted at the end of this first tour, he expressed both enthusiasm and caution, stating that "nature has endowed [New Zealand] with thermal springs with prodigality, but the very abundance of these gifts makes [his] task all the more difficult [and that] to do justice [to all the springs in this country] would require an enormous and unjustifiable expense".<ref name=":4" /> As a priority, he recommended the development of [[Rotorua]], which boasted thermal water of "almost unique quality in almost inexhaustible quantities", an "invigorating" climate, an established reputation and rail access; but also, as a secondary priority, the development of Te Aroha, for its drinkable mineral waters, and Hanmer, for "the invalids [of the [[South Island]]] who could not undertake the long journey to Rotorua".<ref name=":4" />

In 1903, Wohlmann began writing a guide to the mineral waters of New Zealand, intended both for patients and the medical profession.<ref name=":4" /> In 1904, he published the first part devoted to the waters of Rotorua, in which meteorological tables and chemical analyses supplied by the colonial laboratory are complemented by considerations of the curative virtues attributed to these waters and the distractions offered by the region to curists.<ref>{{Cite book |last=Wohlmann |first=Arthur |title=The Mineral Waters and Health Resorts of New Zealand : Part 1, Rotorua |publisher=Department of Tourist and Health Resorts |year=1904}}</ref><ref>{{Cite journal |date=1904 |title=Rotorua |url=https://paperspast.natlib.govt.nz/newspapers/TH19041024.2.23 |journal=Taranaki Herald}}</ref> The work was gradually supplemented with information on other sites, with pagination increasing from 48 pages in 1904 to 82 pages in 1907 and 155 pages in 1914.<ref>{{Cite book |last=Wohlmann |first=Arthur |url=https://archive.org/details/mineralwatersspa00wohliala/page/n3/mode/2up |title=The Mineral Waters and Health Resorts of New Zealand |publisher=University of California Libraries |year=1914}}</ref><ref>{{Cite book |last=Wohlmann |first=Arthur |title=The Mineral Waters and Health Resorts of New Zealand |publisher=Department of Tourist and Health Resorts |year=1907}}</ref> These publications were part of a strategy developed by Donne, the director of the tourism promotion department, to present New Zealand as a "thermal wonderland" and a "cureland", the spa par excellence of the southern hemisphere.<ref>{{Cite journal |last1=Ateljevic |first1=Irena |last2=Doorne |first2=Stephen |date=2002 |title=Representing New Zealand : Tourism Imagery and Ideology |journal=Annals of Tourism Research |volume=29 |issue=3 |doi=10.1016/S0160-7383(01)00077-9}}</ref> According to Peter Hodder, the ambiguous status of Wohlmann's publications, which simultaneously aim to provide scientific data on the composition of the waters and more conjectural information on their alleged virtues, while at the same time addressing a readership of potential tourists and health-care professionals, results in a mixture between compilations of chemical analyses and subjective assessments of the waters' gustatory or curative qualities.<ref name=":5" /><ref>{{Cite journal |last=Hodder |first=Peter |date=2014 |title=Wohlmann, Water and Whisky |url=https://nzic.org.nz/unsecure_files/cinz/2014-78-2.pdf |journal=Chemistry in New Zealand |volume=78 |issue=2}}</ref> Wohlmann made favorable comparisons between New Zealand's mineral waters and those of Europe's most famous spas. Te Aroha's, for example, had a higher proportion of sodium bicarbonate than Vichy's, making it "the strongest alkaline thermal water in the world".<ref>{{Cite journal |last=Wohlmann |first=Arthur |date=1914 |title=he Mineral Waters and Health Resorts of New Zealand |url=https://archive.org/details/mineralwatersspa00wohliala/page/n3/mode/2up |journal=John Mackays}}</ref> However, these analyses will later be called into question when it emerges that the same waters are also rich in arsenic and boron.<ref name=":6">{{Harvtxt|Hodder|2015}}</ref> 

In 1906, Wohlmann was entrusted with organizing part of the Tourism Department's section at the [[Christchurch]] International Exhibition.

== Development of Rotorua ==
Soon after he arrived in Rotorua, Wohlmann decided on the development strategy he would constantly recommend to the authorities: to prioritize the developing the local spa facilities into the largest spa in the southern hemisphere. He points to the economic benefits that can be expected from such a development: "If, through increased attractions, we can attract a thousand more visitors, we can expect a million more pounds to be spent in the country. To attract these visitors, we need to upgrade a spa completely, both in terms of baths and amusements and treatments [...] the baths must not only be places where you can bathe in thermal waters but they must be equipped with all the expensive apparatus of modern balneological methods; and there must not only be decent comfort but a certain level of luxury".<ref name=":4" /> 

He complained both about the dilapidated state of the existing facilities and their dangerous nature, as some baths – which he privately compared to pigsties<ref name=":8">{{Harvtxt|McClure|2004|p=35}}</ref> – were built directly above the springs, exposing their users to [[fumarole]]s.<ref name=":4" /> He was also interested in improving the town's appearance, experimenting with colors that would brighten up building facades while resisting sulfurous vapors.<ref name=":8" /> Initially, his landscaping project was budgeted at ten thousand pounds, and the estimated duration of the work was seven months.<ref>{{Harvtxt|McClure|2004|p=36}}</ref> Despite the apparent support of the government, work did not begin until 1905,<ref name=":9">{{Harvtxt|McClure|2004|p=37}}</ref> an article published in the ''New Zealand Herald'' that same year reflecting the frustration engendered by this procrastination: "we have a brilliant balneologist, but in practice, we have no baths".<ref>{{Cite journal |date=1905 |title=The Rotorua Baths |url=https://paperspast.natlib.govt.nz/newspapers/NZH19050316.2.24 |journal=New Zealand Herald}}</ref>

By August 1908, the work, which had cost around £40,000,<ref>{{Cite journal |last=Rise |first=Frank |date=1912 |title=New Zealand's Thermal Wonderland |journal=Mid-Pacific Magazine |volume=3 |issue=3}}</ref> was sufficiently advanced to allow a partial opening.

In 1913, after returning to Britain for a few months to recover from a fall from a horse, Wohlmann met Dr. Sigmund Saubermann from Berlin, who explained the therapeutic benefits of radioactive mineral water.<ref>{{Cite journal |date=1914 |title=Report of the Balneologist, Rotorua |url=https://paperspast.natlib.govt.nz/parliamentary/AJHR1914-I.2.3.2.2 |journal=Tourist and Health Resorts Department}}</ref> He convinced the government that the public was "radium-mad"<ref>{{Cite book |last=Priestley |first=Rebecca |title=Mad on Radium : New Zealand in the Atomic Age |publisher=Auckland University Press |year=2012 |pages=1–3}}</ref> and secured the purchase of an "activator" from a specialist firm in London to enrich mineral water with radium emanation, or [[radon]], to be administered orally in doses of four to six glasses a day,<ref>{{Harvtxt|Priestley|2017|p=163}}</ref> drunk at "frequent intervals" to "maintain the charge in the blood".<ref name=":12">{{Cite book |last=Wohlmann |first=Arthur |url=https://archive.org/details/mineralwatersspa00wohliala/page/n3/mode/2up |title=The Mineral Waters and Health Resorts of New Zealand |publisher=John Mackays |year=1914}}</ref> Increased urine production, gut excretory activity and sexual activity are among the expected beneficial effects.<ref>{{Harvtxt|Priestley|2017|p=163-164}}</ref> According to Rebecca Priestley and John Horrocks, this therapy was not the result of charlatanism, but of a desire to offer "the best technology available" at a time when the harmfulness of radium was still unknown.<ref>{{Harvtxt|Priestley|2017|p=164}}</ref><ref name=":13">{{Harvtxt|Horrocks|2012|p=150}}</ref> Moreover, Wohlmann adopted a holistic approach to spa treatment,<ref name=":14">{{Cite journal |last=Stewart |first=Cameron |date=2005 |title=The Dawn of Therapeutic Sp |journal=Medical Post |volume=41 |issue=41}}</ref> considering ambience, change of atmosphere and climate to be an integral part of it; this approach went hand in hand with a more commercial argument, highlighting the age-old expertise of the Maoris from which spa-goers could benefit.<ref>{{Harvtxt|Horrocks|2012|p=146}}</ref>

The spa was described as the most beautiful and luxurious building in New Zealand. Journalists pointed out the presence of statues of [[Charles Francis Summers]] in the foyer and the luxury of the spa facilities.<ref>{{Harvtxt|McClure|2004|p=40}}</ref><ref>{{Harvtxt|McClure|2004|p=38}}</ref> Wohlmann, supported by the Department of Tourism, argued that these luxuries were necessary to enable Rotorua to compete with the great spas of international renown, but soon after the official opening, the government gradually became more and more reluctant to finance further investment.<ref>{{Harvtxt|McClure|2004|p=41}}</ref> By 1909, it was clear that the results were not living up to expectations, as the new facilities, despite their luxury, were not sufficient to motivate international spa-goers to make the long journey to New Zealand: the increase in revenue for the year was only £612, and the number of foreign spa-goers remained limited to 95 Australians, 40 Britons and 35 from other countries.<ref name=":20" />

}}In the first months of operation, the Rotorua spa began to show signs of deterioration. The high level of sulfur in the water led to rapid corrosion of the piping, while sulfur vapors blackened the paint on the walls, attacked the ventilation and loosened the tile joints.<ref name=":11" /> In addition, a dozen minor earthquakes occurred shortly after the opening of the new building.<ref name=":14" /> Wohlmann had to write several letters to the Department of Tourism, pointing out that the plasterwork on the walls and ceilings was cracking, with chunks of plaster liable to fall off and injure guests. These problems, attributable as much to the nature of the water as to errors in the building's design, led the government to consider closing the building at the end of the 1920s.<ref name=":20" />

At the same time as managing the spa, Wohlmann continued his work as a physician. In his 1914 book on mineral waters, he summarized the results obtained on 593 patients he had personally treated over the previous three years at the new Rotorua establishment estimating that 536 of them had improved, particularly in cases of rheumatism and arthritis, but also neurasthenia. According to Ralph Johnson, this retrospective synthesis "regrettably" lacks a critical section, particularly on the "supreme importance" attributed to radioactivity in balneology.<ref name=":20" />

Shortly after the outbreak of the [[First World War]], Wohlmann was prompted by growing anti-German sentiment to stop using his surname.<ref name=":17">{{Harvtxt|McClure|2004|p=85}}</ref><ref>{{Cite book |url=https://books.google.com/books?id=KukkAQAAIAAJ&pg=PA274 |title=Parliamentary Debates |publisher=House of Representatives |year=1916 |pages=274}}</ref> He adopted his mother's maiden name, Herbert, and announced it in the press.<ref name=":20" />

In 1915, he assumed responsibility for a newly-built hospital in Rotorua for convalescent soldiers, providing treatment which he described in 1916 and 1918 in articles for the ''New Zealand Medical Journal''<ref>{{Cite journal |last=Herbert |first=Arthur |date=1916 |title=The Physical Treatment of Wounded : Elastic Support in Muscular Paralyses |journal=New Zealand Medical Journal |volume=15}}</ref><ref>{{Cite journal |last=Herbert |first=Arthur |date=1918 |title=The (Protopathic) Sensory Nerve Areas of the Hand |url=https://assets-global.website-files.com/5e332a62c703f653182faf47/5e332a62c703f62a1d2fcb10_100%20Years%20Ago%20FINAL.pdf |journal=New Zealand Medical Journal |volume=17}}</ref> and later in a book published in 1918,<ref>{{Cite journal |last=Herbert |first=Arthur |date=1918 |title=Military Physical Orthopædics : Part 1, Gunshot Wound of Nerve |url=https://natlib-primo.hosted.exlibrisgroup.com/primo-explore/fulldisplay?vid=NLNZ&docid=NLNZ_ALMA21231567110002836 |journal=Government Printer}}</ref> for which he was awarded the [[Order of the British Empire]].<ref name=":20" /> According to Ralph Johnson, these works are remarkable both for the precision of their lesion descriptions and for the care with which Wohlmann kept abreast of medical news.<ref name=":20" /> However, a review published in the ''British Medical Journal'' in 1920 felt that the work reflected the difficulties of New Zealand's isolation during the war, and that the author tended to exaggerate the benefits of his elastic-based devices.<ref>{{Cite journal |date=1920 |title=Review: Military Physical Orthopaedics |journal=British Medical Journal |volume=1 |issue=3103}}</ref>

in 1919, Wohlmann was promoted to Major and reinstated in the New Zealand Army.<ref name=":17" /> In the same year, he was appointed spa therapist in New Zealand.<ref name=":20" /> In this position, he undertook a tour of the country to inspect and classify the hot springs, which he published in 1921 in ''The Official Guide to the Hot Springs of New Zealand''.<ref name=":21">{{Cite journal |last=Herbert |first=Arthur |date=1921 |title=The Hot Springs of New Zealand |url=https://archive.org/details/hotspringsofnewz00herbuoft/ |journal=H. K. Lewis}}</ref> According to Peter Hodder, this guide took account of worldwide advances in thalassotherapy and highlighted the variety of mineral springs available on the island.<ref name=":6" /> 

Wohlmann resigned as balneologist in 1919 and returned to London, where he practiced medicine privately in Kensington. In 1921, he published ''The Hot Springs of New Zealand'', a detailed work on spa treatments in New Zealand.<ref name=":21" /> In the preface, Wohlmann argues that, while New Zealand spas cannot compete socially with those in Europe, the change of atmosphere is one of the important aspects of a cure, and that in this respect New Zealand, with "its strange and wonderful scenery, its splendid lakes, [...] its geysers, its bubbling springs, [...] its picturesque Maori villages, [...] its housewives washing their clothes in a hot spring or nonchalantly cooking in a steam pit, offers more of a change of scenery than a visit to a continental spa".<ref name=":21" /><ref>{{Cite book |last=Werry |first=Margaret |url=https://books.google.com/books?id=gWojlb5V5fgC&pg=PA33 |title=The Tourist State : Performing Leisure, Liberalism, and Race in New Zealand |publisher=University of Minnesota Press |year=2011 |pages=33|isbn=978-0-8166-6605-8 }}</ref> According to John Horrocks, this remark testifies to an "openness to the importance of suggestion",<ref name=":13" /> in the context of a balneologist's interest in the care of "indefinite and borderline cases"<ref>{{Cite journal |last=Herbert |first=Arthur |date=1921 |title=The Hot Springs of New Zealand |journal=H. K. Lewis}}</ref> and, more generally, in the idea – developed a few years earlier by [[George Miller Beard]] with his thematization of the concept of [[neurasthenia]] – that the cause of nervous disease was modern civilization, Wohlmann thus expressed a sincere alignment with the theme developed by the New Zealand government's tourism propaganda.<ref>{{Harvtxt|Horrocks|2012|p=151-152}}</ref>

In one of his latest publications, Wohlmann, without going back over the benefits of a change of scenery during a spa treatment, nor over the therapeutic virtues of mineral waters, recommended not underestimating the advantages of simple hydrotherapy with ordinary hot water available in a city like London, combined with "massage, manipulation and movement, using electricity, light and dry heat".<ref>{{Cite journal |last=Herbert |first=Arthur |date=1928 |title=A Clinic for Physical Treatment in London |journal=British Medical Journal |volume=1 |issue=3496|pages=33–34 |doi=10.1136/bmj.1.3496.33-b }}</ref> Peter Hodder noted that Wohlmann had already been convinced in 1914 that the effectiveness of some of his treatments was due more to the temperature of the water than to its composition.<ref name=":6" /><ref name=":12" /> 

He died on March 3, 1944 in Richmond.<ref name=":1" /> The position of government balneologist was held by Dr. Duncan from 1919 to 1942, then by Dr. Blair from 1942 to 1957,<ref name=":20" /> and was not renewed after 1957. This evolution is consistent with the changing perception of geothermal water issues in New Zealand since the mid-twentieth century, first seen as a spectacle for tourists, then as a remedy in the form of baths or beverages, then as a leisure activity, before being mainly considered today from the angle of energy supply.<ref name=":6" />
