Dr. Seares's most important contributions to the science of astronomy pertain to the nature, brightness, and distribution of the stars. His investigations in these and allied subjects are fundamental, and in this field he is recognized as an outstanding authority.... His painstaking work in determining fundamental standards over the whole range of observable photographic magnitudes is recognized by photometric observers the world over as an achievement of the highest importance to astronomy. It was also in 1940 that Seares's wife passed away. Two years later, Seares married his long-time colleague at Mt. Wilson, Mary Joyner.
