Note	Lora L. Corum*	0			1	1924
	Floyd Davis*	0			1	1941

* Lora L. Corum and Floyd Davis are credited as being co-winners of the Indianapolis 500 in 1924 and 1941, respectively. However, as the winning entries in either race led only after their secondary drivers drove (and to the conclusion), Corum and Davis are not credited with leading any of those laps, nor did they lead throughout the remainder of their careers.

Autolite Pacemakers Club

In 1964, Autolite created the "Pacemakers Club," which recognized drivers who had led at least one lap during the Indianapolis 500. It quickly rose in stature and popularity, and became a highly-sought after honor associated with the Indianapolis 500. After changes in sponsorship, the organization was renamed the Leaders Circle Club.

The qualifications were simple, and driver who had led at least one lap during race, whether living or already deceased, were recognized as members. At its inception, 102 drivers were listed as members. A total of 56 were deceased at the time, and 46 were living.

Honorees receive a jacket, and are honored at a banquet in their honor. The number of new members inducted at the banquet varies annually, as it is solely based on the previous year's first-time lap leaders. Some years can have as few as one or zero new members inducted, while other years have had as many as 4-5. The "club" is still active as of 2012.
