• After her family moved to Europe, Dorothea attended the University of Paris (Sorbonne), where she excelled in mathematics and astronomy.

• In 1893, she became the first woman to earn a doctorate in astronomy from the Sorbonne. Her thesis, focused on Saturn’s rings, earned her the Prix des Dames for excellence.

Career Highlights:

1. Director of the Bureau of Measurements at Paris Observatory:

• Klumpke was appointed director at the Paris Observatory, where she worked on creating stellar catalogs and measuring star positions.

• She was involved in the Carte du Ciel project, an ambitious international effort to map the entire sky.

2. Solar Eclipse Expeditions:

• She joined several scientific expeditions to observe solar eclipses, contributing valuable data about the Sun’s corona and magnetic activity.

3. Asteroid Research:

• Klumpke was honored with the naming of the asteroid 339 Dorothea, recognizing her achievements in astronomy.

4. Writings and Legacy:

• She wrote extensively on astronomy and published papers that advanced the understanding of stellar properties and celestial mechanics.

Marriage and Later Life:

• In 1901, she married British astronomer Isaac Roberts, a pioneer in astrophotography. Together, they collaborated on research until his death in 1904.

• After her husband’s death, she published "Photographs of Stars, Star Clusters, and Nebulae", based on his work, further solidifying their joint legacy.

Awards and Recognition:
