Throughout his career, a primary focus of Ed’s research was on ultraviolet (UV) spectroscopic observations. He was hired in Princeton originally to work on sounding rocket instrumentation and data analysis of UV spectra from bright stars, and then he spent more than a decade on research with the Copernicus satellite, during which time he was the director of the data reduction team. Later, Ed’s research made use of the International Ultraviolet Explorer, the Hubble Space Telescope (HST), and the Far Ultraviolet Spectroscopic Explorer, as well as many ground-based telescopes, and he worked on instrument and facility design for the Starlab project. ‬For two decades beginning in 1980, Ed was heavily involved in the NASA-sponsored Interstellar Medium Absorption Profile Spectrograph‭ (‬IMAPS‭) project as Principal Investigator. ‬This instrument flew on sounding rockets and also operated on two ORFEUS-SPAS missions launched into orbit by the Space Shuttle‭.‬
