In Memoriam: William Sinton
William Sinton, a member of the IfA faculty from its beginnings until his retirement in 1990, died March 16 at his home in Flagstaff, Arizona, after a ten-year battle with amyotrophic lateral sclerosis (Lou Gehrig's disease). He played a key role in the early development of Mauna Kea Observatories and was a pioneer in the field of infrared planetary astronomy. Sinton led one of the first ground-based systematic observing programs of Io's volcanoes, and he helped to found the International Jupiter Watch in 1987.
