This accession consists mostly of Smithsonian Astrophysical Observatory (APO) Waste Books containing data from solar constant studies. Materials also include eleven letters from Charles Greeley Abbot to Frederick E. Fowle concerning solar constant studies at Mt. Wilson, California, 1906.
Charles G. Abbot (1872-1973), the fifth Secretary of the Smithsonian Institution, came to the Institution in 1895 as an assistant to Secretary Samuel P. Langley in the Smithsonian Astrophysical Observatory. In 1907 he was named Director of the Astrophysical Observatory, a position which he held until his retirement in 1944. He became an Assistant Secretary of the Institution in 1918, and served as Secretary from 1928 to 1944. Most of Abbot's research centered around studies of solar radiation and attempts to determine the relationship between solar variations and the earth's weather.
