Tas is one of the North Bethesda Rotary Club Charter Members and one of its early Club Presidents. He talked about life in Macedonia under the Nazis and the Communists where he escaped death sentences twice and his Jewish friends didn’t. Because his father was a USA citizen, Tas was also a USA citizen at birth. He completed medical school in Greece and studied chemistry at Pittsburgh University and received a PHD in Bio physics. From 1954 to 1961 Tas served in the US Army at the Walter Reed Hospital Institute of Research, and the Armed Forces Institute of Pathology (AFIP). In 1965 he established the Tousimis Biodynamics Laboratories. Tas showed us one of his patents which read “Integrated Processing and Critical Point Drying Systems for Semiconductor and Mems Devices”.
