during the 1950s and 1960s. In 1951, Prince began a collaboration with Arthur Covington, Canada's pioneering solar radio astronomer, that lasted into the 1970s. Their work was an effort to coordinate radio and optical studies of solar flares for better classification and explanation. In 1955, Prince was awarded the Annie J. Cannon Medal by the American Astronomical Society for her work in solar flare investigations.
Prince was appointed associate director of McMath-Hulbert in 1962, a post in which she served until her retirement in 1976. She continued her observations at the Observatory after her appointment as professor emerita until 1979. 1
