Named in memory of Rupert Wildt (1905–1976), who was awarded the Eddington Medal by the Royal Astronomical Society in 1966 for his discovery in 1939 that the negative hydrogen ion is an important contributor to the opacity of the solar atmosphere. He identified the absorption bands in the red part of the spectra of the outer planets as due to methane and ammonia, and he made pioneer calculations of models for the interiors of the giant planets. A professor in Yale University’s Department of Astronomy for many years, he was Yale’s first scientific representative on the Board of Directors of the Association of Universities for Research in Astronomy and served two terms as AURA president and chairman of the board (1965–1968, 1971–1974).
