On August 12, 1919, Anglo-American astrophysicist Margaret Burbridge (nee Peachey) was born in Cheshire, England.

Margalit Fox's obituary in the New York Times:
She was considered one of the foremost astronomers in the world, long regarded as a trailblazer for women in the field.

Dr. Burbidge was the first woman to serve as director of the Royal Observatory, the storied British institution. She was also a contributor to the design of instruments carried aboard the Hubble Space Telescope and a recipient of the National Medal of Science, bestowed in 1985 by President Ronald Reagan.

“She has a huge imprint on the history of modern astronomy and cosmology and nuclear astrophysics,” George Fuller, a theoretical astrophysicist at the University of California, San Diego, where Dr. Burbidge taught for many years.

Burbridge made notable contributions to the theory of quasars, to measurements of the rotation and masses of galaxies, and was the lead author on a groundbreaking paper describing how chemical elements are formed in the depths of stars through nuclear fusion. She was the first woman to be president of the American Astronomical Society.
