Executive summary: Astronomer at Berkeley Military service: US Army (Chemical Warfare Service, 1918-20) Astronomer Armin O. Leuschner was born in Detroit, but while still a toddler he moved to Germany with his mother, following his father's death. As a man he returned to America and studied under James Craig Watson, and became the first graduate student at Lick Observatory. For his PhD at the University of Berlin, he was discouraged from writing about orbit theory, as his advisors felt there was little left to learn on the topic. He later devised a simplification of differential corrections, improved the methodology for determining the courses of planetoids and comets, and oversaw a survey of all the known minor planets. He founded the Astronomy Department at Berkeley, and for forty years served as director of the student observatory there, which was renamed in his honor days after his death.
