History

Harvard Observatory is historically important to astronomy, as many women including Annie Jump Cannon, Henrietta Swan Leavitt, and Cecilia Payne-Gaposchkin performed pivotal stellar classification research. Cannon and Leavitt were hired initially as "computers" to perform calculations and examine stellar photographs, but later made insightful connections in their research. [1] Annie Jump Cannon (December 11, 1863 – April 13, 1941) was an American astronomer whose cataloguing work was instrumental in the development of contemporary stellar classification. ... Henrietta Leavitt Henrietta Swan Leavitt (July 4, 1868 – December 12, 1921) was an American astronomer, and the deaf[1] daughter of a Congregational church minister. ... Cecilia Payne-Gaposchkin (May 10, 1900 – December 7, 1979) was an English-American astronomer who in 1925 was first to show that the Sun is mainly composed of hydrogen, contradicting accepted wisdom at the time. ... In astronomy, stellar classification is a classification of stars based initially on photospheric temperature and its associated spectral characteristics, and subsequently refined in terms of other characteristics. ... Before mechanical and electronic computers, the term computer, in use from the mid 17th century, meant a human undertaking mathematical calculations. ...
