The Bulletin of the Atomic Scientists remembrs Kosta Tsipis (1934–2020)

The Bulletin of the Atomic Scientists mourns the passing of a friend and longtime supporter, Kosta Tsipis, who died at his home on Saturday, November 7, at the age of 86.

A native of Greece, Tsipis emigrated to the United States in 1954 to study electrical engineering and physics at Rutgers University. After earning a doctorate at Columbia University, in 1966 he joined the physics department at the Massachusetts Institute of Technology. A little more than 10 years later, he co-founded the Program in Science & Technology for International Security at MIT.

In 1984, he received the American Physical Society’s annual Leo Szilard Lectureship Award, which honors outstanding accomplishments in promoting the use of physics for the benefit of society in such areas as the environment, arms control, and science policy.

Tsipis was committed to disarmament and was generous with his time, serving organizations such as the Council for a Livable World, the Stockholm International Peace Research Institute, and the Greek Institute for International and Strategic Studies. He was a member of the Bulletin’s Board of Sponsors for nearly 25 years, from 1995 until his death.
