As of July, 2020, The Interactive Fly, almost 25 years old, is now in its 88th edition and contains over 1600 genes. Early support and encouragement for this project came from Laurie Iten and Ida Chow of the Society for Developmental Biology and Bill Gelbart of FlyBase. The SDB has kindly carried The Interactive Fly on their server since the beginning, and SDB staff has helped in the maintenance of the web site. This project would be impossible without the design, editing efforts, and advice of my wife, Judy.

Ward Odenwald of the Neural Cell-Fate Determinates Section of NINDS and Michela Serpe of the Section on Cellular Communication of NICHD, National Institutes of Health, have been unwavering in their backing and encouragement. Manu Tiwari of the Molekulare Zellbiologie Institut I für Anatomie, University of Cologne has made significant contributions to The Interactive Fly. The comments, updates and corrections provided by the Drosophila community have been, and will continue to be, greatly appreciated.

Many thanks to all,

Tom Brody
