Aigler was a University of Michigan Law School professor who was heavily involved in university athletics. The collection consists primarily of extensive correspondence and Board in Control of Athletics documentation, but also includes papers written in both his legal and university capacities.
The Aigler collection consists of six series covering his collegiate and professional life: Correspondence, Board in Control of Athletics, Writings, University of Michigan Teaching and Administration, Legal Files, and Biographical. Through correspondence and topical files, the collection documents Aigler's university life and his life-long interest in intercollegiate athletics. The collection has strong potential for research regarding early University of Michigan athletics, and general correspondence to and from Aigler. While there is some material related to Aigler's teaching career, this area is not particularly strong.
