Robert Mason died Oct. 24, 2012, at Brightwood, a retirement community in Lutherville, Md. He was 95.

Born in Birmingham, Ala., Bob prepared for Princeton at Ramsay High School. At Princeton he majored in biology and graduated with high honors. He was a cartoonist for The Daily Princetonian, belonged to Terrace Club, and taught at Jamesburg State Training School for Boys. Bob graduated from Johns Hopkins Medical School, specializing in internal medicine.

Bob enlisted in the Army the day after Pearl Harbor and landed at Omaha Beach on D-Day, helping to establish a field hospital at St. Lô. This hospital was transferred to Belgium and was under buzz-bomb attack during the Battle of the Bulge.

After the war he returned to Johns Hopkins Hospital and also practiced privately. His major medical contribution was developing the In-Exercise Electrocardiographic Stress Test, which has become the standard test worldwide for detection of coronary artery disease.

Bob was an accomplished photographer and woodworker. After retiring in 1986, he pursued his passion for hiking and climbed Grand Teton, the Matterhorn, and Mount Kilimanjaro, and once reached the base camp on Mount Everest.

Bob is survived by his wife, Beverly; sons Steven and Andrew; daughter Elizabeth; stepsons Benson Legg, Christopher Legg, Bruce Matthai, and William Legg; stepdaughters Beverly Ciccarone and Anna Reigeluth; and 30 grandchildren. To them all, ’38 extends heartfelt sympathy.
