Annie Jump Cannon (December 11, 1863 – April 13, 1941) was an American astronomer whose cataloging work was instrumental in the development of contemporary stellar classification.
The Harvard system is a one-dimensional classification scheme by astronomer Annie Jump Cannon, who re-ordered and simplified a prior alphabetical system.

Sarah Frances Whiting

Cannon studied under Sarah Frances Whiting, one of the few women physicists in the United States at the time, and went on to become the valedictorian at Wellesley College.
Sarah Frances Whiting (August 23, 1847 – September 12, 1927), American physicist and astronomer, was the instructor to several astronomers, including Annie Jump Cannon.

Harvard Computers

In 1896, Cannon became a member of the Harvard Computers, a group of women hired by Harvard Observatory director Edward C. Pickering to complete the Henry Draper Catalogue, with the goal of mapping and defining every star in the sky to a photographic magnitude of about 9.
The Harvard Observatory, under the direction of Edward Charles Pickering (1877 to 1919) and, following his death in 1919, Annie Jump Cannon had a number of women working as skilled workers to process astronomical data.

Cannon's mother was the first person to teach her the constellations and she encouraged her to follow her own interests, suggesting that she pursue studies in mathematics, chemistry, and biology at Wellesley College.
They include the first woman to be named professor of clinical medicine Connie Guion, class of 1906; architect Ann Beha, class of 1972; author Harriet Stratemeyer Adams (pen name Carolyn Keene) class of 1914; astronomer Annie Jump Cannon, class of 1884; astronaut Pamela Melroy class of 1983; screenwriter Nora Ephron, class of 1962; composers Elizabeth Bell and Natalie Sleeth; and professor and songwriter Katharine Lee Bates.

This relationship gave Cannon access to the Harvard College Observatory.
Harvard College Observatory is historically important to astronomy, as many women including Annie Jump Cannon, Henrietta Swan Leavitt, Cecilia Payne-Gaposchkin, and Williamina Fleming performed pivotal stellar classification research.

Williamina Fleming

This left the problem to the ideas of Henry Draper's niece Antonia Maury (who insisted on a complex classification system) and Williamina Fleming (who was overseeing the project for Pickering, and wanted a much more simple, straightforward approach).
Later, her colleague Annie Jump Cannon reordered the classification system based upon the surface temperature of stars, resulting in the Harvard system for classifying stars that is still in use today.

In 1890, the Harvard College Observatory constructed an observation station in Arequipa, Peru in order to study the sky in the Southern Hemisphere, and a study of bright stars in the southern hemisphere was published by Annie Jump Cannon and Pickering in 1901.

Annie J. Cannon Award in AstronomyAnnie J. Cannon AwardAnnie Jump Cannon Award
The American Astronomical Society presents the Annie Jump Cannon Award annually to female astronomers for distinguished work in astronomy.
The award is named in honor of American astronomer Annie Jump Cannon, and is the only award in astronomy restricted to women only.

Cecilia Payne-Gaposchkin

The astronomer Cecilia Payne collaborated with Cannon and used Cannon's data to show that the stars were composed mainly of hydrogen and helium.
Under the direction of Harlow Shapley and Dr E. J. Sheridan (whom Payne-Gaposchkin described as a mentor ), the observatory had already offered more opportunities in astronomy to women than did other institutions, and notable achievements had been made earlier in the century by Williamina Fleming, Antonia Maury, Annie Jump Cannon, and Henrietta Swan Leavitt.

The episode pays homage to the discoveries of two female astronomers, Cecilia Payne (voiced by Kirsten Dunst) and Annie Jump Cannon (voiced by Marlee Matlin), and the obstacles faced by women scientists, especially those working in the early 20th century.
