Cogan Ophthalmic History SocietyThe Cogan Ophthalmic History Society meets once a year for a day and a half, and approximately 30 short historical talks are presented. Topics range the entire past of ophthalmology and visual science and are limited only by the imagination and interest of its members. Recent presentations have included a survey of early ophthalmic instruments by Richard Keeler, the unusual career of Ida Mann, DBE, MB, DSc(London), MA, by Stan Thompson, MD, and Harry Truman's hyperopia by Darron Bacall, MD. Only a particularly unimaginative audience would not find something fascinating and previously unknown in the papers presented.
