Annie Jump Cannon

Annie Jump Cannon was an American astronomer known for her groundbreaking work in classifying stars. In the early 20th century, she developed the Harvard Classification Scheme, which categorizes stars based on their temperature and spectral characteristics. This system helped scientists better understand stellar evolution and the life cycles of stars. Cannon's meticulous observations and her role in a team of women astronomers, known as the "Harvard Computers," significantly advanced our knowledge of the universe, making her a key figure in observational astrophysics and contributing to the study of solar and stellar physics.
