- In 1929, shortly after becoming Secretary of the Smithsonian Institution, Charles Greeley Abbot established a Division of Radiation and Organisms to study relationships between solar radiation and the growth of plants. This unsigned optical bench is probably the one that this Division purchased in 1930. Frederick Sumner Brackett (then on the payroll of the Fixed Nitrogen Lab at the U.S. Department of Agricultura) was research associate in charge of the Division. The Division became the Smithsonian Radiation Biology Laboratory in the 1960s.
