Aaron Marcus, a long-time member of the International Society on Thrombosis and Haemostasis (ISTH), died peacefully in his sleep on May 6 at the age of 89. Marcus was a leader and mentor to many in the field of thrombosis and hemostasis for more than 50 years.
There was always an omnivorous, endearingly daffy curiosity in play, and an eagerness to share his enthusiasms. He was born in Brooklyn in 1925 and educated at the University of Virginia and New York Medical College. He spent more than fifty years at the Veterans Administration Harbor Healthcare System, dedicating himself to experimentation in a narrow, instrument-crammed lab. One colleague called the place "his secret garden of science"--and the harvest went on for decades, abetted by a productive association with Weill Cornell Medical College, where he was a Professor of Medicine. He was the kindest, funniest, and quirkiest of human beings, and will be missed forever by those who loved him.
