In the mid-20th century, the Bond Astronomical Club, founded by APS Member and noted astronomer Dr. Harlow Shapley (APS 1922) gathered regularly in Cambridge, MA. The Club maintained an active program of annual dinners, summer picnics, trips to observatories, and presentations featuring prominent speakers—several of whom were also APS Members including Cecelia Payne-Gaposhkin (APS 1936) and Owen Gingerich (APS 1975)—to discuss cutting-edge discoveries in physics and astronomy. Among their records that APS recently acquired are these star maps from 1932 (from observations made at the Valley View Observatory in Pittsburgh, PA).
