Mark Keyser was born in 1950 in Northampton, Massachusetts to Karl Anton Keyser (1918-1995) and Dorothy M. Borger (1923-2003). He grew up near Amherst in a veterans’ housing project and visited his extended family in Washington, D.C. as a boy. Today Mark lives in Seabrook, New Hampshire, where he was enjoying a career as a substitute teacher until the COVID-19 pandemic hit in February/March 2020. His father Karl was Amelia Louisa Keyser Heurich’s nephew and grew up in Washington, D.C., at 1777 Lanier Place, NW. Karl served as Executive Officer (second in command) in the U.S. Navy in World War II on the U.S.S. Eberle in the North Atlantic and Mediterranean theatres of combat. He stayed in the U.S. Navy Reserve until about 1973. He earned several graduate degrees from Carnegie Mellon University (then the Carnegie Institute of Technology) in Pittsburg and had a long career as a professor of mechanical engineering and material sciences at the University of Massachusetts (Amherst?). Mark’s mother Dorothy had a career as a model in New York City where she crossed paths with actress Tippi Hedren before the war. During the war she worked at Sperry on Long Island as part of the war effort. After she married and the war ended, she concentrated on raising her three children. This interview also includes material about Mark’s grandfather, Adolph G. (“Dolph”) Keyser Sr. (1874-1955). Dolph was an attorney in Washington who Mark remembers had an office on K Street, NW, and who he believes worked for Christian Heurich, primarily handling Heurich’s real estate holdings. Dolph attended law school at Georgetown. Amelia Heurich’s diary records a moment in 1914 when her brother was not promoted to a secretarial/bookkeeping position at the brewery.
