Born in Philadelphia, PA, Duke pursued his undergraduate studies on the West Coast, where he received his AB degree in 1947 from the University of California. From there he went to the University of Chicago, which, in 1950, conferred on him a PhD in astronomy. While working on his doctorate, Duke was also an assistant at the Yerkes Observatory. Afterwards, from 1950 to 1951, he was an assistant professor of astronomy at the University of North Carolina and also the assistant director of the Morehead Planetarium in Chapel Hill. In 1951 Duke received an appointment as an assistant professor in astronomy and physical sciences at the University of Florida. By 1954, when he departed Florida, he had risen to an associate professor.

For the next dozen years, until he was appointed professor of astronomy at the University of Miami in 1966, Duke took a series of positions with a variety of employers. He was head of the Visibility Branch at the US Naval Electronics Laboratory (1954-1955); he was a research engineer for Convair Astronautics (1955-1957); a senior engineer at the Atlantic Missile Range of the Radio Corporation of America (1957-1959); a member of the technical staff of the Institute for Defense Analysis in Washington, DC (1959-1962); a consultant for the Commanding General of the North American Air Defense Command (1961-1962); a staff scientist to the vice president of research for the Autonetics Division of North American Aviation, Inc (1962-1964); and director of aerospace programs at Data Dynamics, Inc. (1964-1965).

Starting in 1966, Duke enjoyed almost two decades in his position as professor of astronomy at the University of Miami. He specialized in observational astrophysics, astrometry, missile and satellite tracking instrumentation, data reduction, satellite and interplanetary orbits, celestial navigation, atmospheric optics, and planetarium operation.
