Thomas Augustus Jaggar, Jr

Thomas Augustus Jaggar, Jr In 1906, already a much-published, respected, well-known geologist, writer and lecturer, he became head of MIT’s department of geology. Jaggar saw the need for full-time, on-site study of volcanoes. He left MIT, moved to Kilauea to start the observatory, and devoted the remainder of his life to a study of volcanoes. When he came to the Islands, he joined the efforts of George Lycurgus (operator of the Volcano House) and newspaperman Lorrin Andrews Thurston who were working to have the Mauna Loa and Kilauea Volcanoes area made into a National Park. Jaggar retired in 1940 and continued his research at the University of Hawai‘i at Mānoa until his death on January 17, 1953.
