In the South Yard behind the Smithsonian Institution Building or "Castle", preparations are being made for a solar broadcast. The broadcast, held on September 30, 1936, hade fifth Smithsonian Secretary and astrophysicist Charles G. Abbot test his solar radiation steam boiler of his design. The National Broadcasting Company (NBC) filmed the test and by operating an electric generator a short program was broadcast by solar power. In this image, Secretary Abbot stands on a platform in front of a group of men (probably journalists) on the left and Assistant Secretary Alexander Wetmore stands to his right.
