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.
