It is with deep sadness that the National Headache Foundation announces the passing of its Executive Chairman and Founder, Seymour Diamond, M.D.

Dr. Diamond was a world-renowned leader in headache medicine and an extraordinary advocate for those experiencing migraine and other chronic forms of headache. Born in Chicago to Rose (Roth) and Nathan Diamond, on April 15, 1925, he was educated in the Chicago Public Schools, Loyola University, and received his M.D. from the Chicago Medical School.

As a family practitioner with a keen interest in research, he started his trek in headache medicine in 1964 with an article and poster on “Depressive Headache.” Dr. Diamond never looked back and went on to become an officer in the American Association for the Study of Headache (now the American Headache Society) and founded the National Headache Foundation in 1970 to serve patients, their families, and their health care practitioners. He was the Founder and Director Emeritus of the Diamond Headache Clinic in Chicago, from which he retired in 2010. Dr. Diamond contributed over 500 articles on headache in the professional literature and was the author and editor of several texts in headache medicine.

He is survived by his wife of 71 years, Elaine Flamm Diamond, as well as his three daughters – Judi ( the late Nathan) Diamond-Falk, Dr. Merle Diamond, and Amy (Charlie Morey) Diamond. He was devoted to his grandchildren: Brian Diamond-Falk (Dr. Katherine Diamond-Falk), Emily (Alex) Horowitz, Max (Debbie) Barack, Michael Barack, Jacob Barack, and Zachary Barack; and to his great-grandchildren (Zevon, Oliver, and Veronica Diamond-Falk). He is also survived by his sister, Idell (the late Fred) Applebaum, and many nieces and nephews.

The family has requested contributions be made to the National Headache Foundation.
