Biography of Annie Jump Cannon

Annie Jump Cannon was born on December 11, 1863, in Dover, Delaware. She grew up in a family with four older step-siblings and two younger brothers. Her mother, Mary Elizabeth Jump, instilled in her a love for the stars and astronomy.

Education

Cannon excelled in school, particularly in mathematics. In 1880, she enrolled at Wellesley College in Massachusetts, one of the leading academic institutions for women in the United States at the time. However, her health suffered due to the cold weather, and she almost became deaf after contracting scarlet fever. In 1884, Cannon graduated from college with a degree in physics.

Early Career

After returning home, Cannon found it difficult to find suitable employment due to her partial hearing loss. In 1892, she traveled to Europe to photograph a solar eclipse. Upon her return, she reached out to her former professor, Sarah Frances Whiting, who hired her as an assistant. This opportunity allowed Cannon to pursue graduate studies in physics and astronomy.

Work at Harvard

To gain access to better telescopes, Cannon applied to Radcliffe Women's College at Harvard and became part of the Harvard College Observatory. In 1896, she became an assistant to Edward Charles Pickering and later received her master's degree in 1907. Cannon played a crucial role in the creation of the Henry Draper Catalogue, a comprehensive catalog of stars and their spectra. She classified approximately 230,000 stars and also published catalogs of variable stars, including the discovery of 300 new ones.

Contributions and Recognition

Cannon's work as an astronomer continued for over 40 years, during which time women began to gain recognition in the scientific community. She was awarded the Henry Draper Medal in 1931 and became the first woman to receive an honorary doctorate from Oxford University in 1925. Cannon was also the first woman elected to the American Astronomical Society. In honor of her contributions, a crater on the Moon and an award for women astronomers have been named after her.

Legacy

Annie Jump Cannon passed away on April 13, 1941, at the age of 77. Her groundbreaking work in classifying stars based on their spectra played a crucial role in the development of modern stellar classification. Cannon's dedication and achievements paved the way for future generations of women in astronomy.
