Secretary Charles Greeley Abbot established the Division of Radiation and Organisms in 1929. Its function was to investigate the effects of solar radiation upon living organisms, mainly plants, and the division was part of the Smithsonian Astrophysical Observatory.
See negatives SIA2011-1306 and 34425.
The Division of Radiation and Organisms was located in the basement of the Smithsonian Institution Building. Shown here is apparatus for studying phototropism (bending toward light) of seedlings, in connection with experiments to determine effects of wave lengths of light on growth. Photo shows Earl S. Johnston at work.
