Leonard Carmichael, Seventh Secretary of the Smithsonian

Dr. Leonard Carmichael led the Smithsonian Institution through many changes during his tenure as the seventh Secretary of the Smithsonian. He presided over new museums and facility openings, special acquisitions, and exciting exhibitions. Because Carmichael was hired from outside of the Smithsonian, he brought a new perspective, his academic background, and skills to thrust the Institution into the modern age. 

In 1953, the Smithsonian Institution’s seventh Secretary was sworn into office. Dr. Leonard Carmichael, a psychologist, served from 1953–1964 and was the first Secretary to be hired from outside of the Institution.

Some historians regard Carmichael as the Secretary responsible for leading the Smithsonian into the modern age, raising funds to modernize outdated exhibitions and personally interviewing and hiring a group of young, talented researchers. During his time as Secretary, the Smithsonian created the National Portrait Gallery, expanded the Natural History Building, and updated and moved the Smithsonian Astrophysical Observatory to Cambridge, Massachusetts, where the observatory was the only laboratory in the United States able to track the Soviet’s Sputnik satellite in 1957. Additionally, Carmichael pushed to update and improve the National Zoological Park, and the Friends of the National Zoo was created to aid in the future of the Zoo during his time as Secretary.
