Gail Fidler, OTR, FAOTA (1916–2005), was an occupational therapist, leader, educator, and scholar for 65 years. She graduated from the Philadelphia School of Occupational Therapy in 1942, with an interest in psychiatry. In 1948, she proposed activity analysis as a way to empirically examine activities. Fidler’s scholarship promoted the therapeutic value of purposeful activity and explored its psychodynamics, and she wrote 13 books and many articles. She served on AOTA’s Executive Board and as its Associate Executive Director for Practice, Education, and Research. She received the Eleanor Clarke Slagle Lectureship in 1965, which focused on education, and AOTA’s Award of Merit in 1979. Read Fidler’s In Memoriam.
