American astrophysicist Jacqueline Hewitt was born on September 4, 1958 in Washington, D.C. She was the first person to discover an Einstein ring.

Interestingly, when Hewitt graduated magna cum laude from Bryn Mawr College, it was with a degree in economics. However she had become interested in astronomy and went to the Massachusetts Institute of Technology (MIT) for her graduate studies. She began to study gravitational lensing using the Very Large Array (VLA) in New Mexico, a very large radio telescope.

After completing her Ph.D, she was made postdoctoral fellow at MIT. While analyzing data from her graduate studies, she made an astounding discovery. She was the first person to discover an Einstein ring. Einstein had said that a massive object – like a galaxy, for example – could bend the light from another object, behaving like a lens.

Hewitt is currently the Julius A. Stratton Professor in Electrical Engineering and Physics at MIT. She's also received several fellowships and awards as well as being elected a Legacy Fellow of the American Astronomical Society in 2020.

In addition to her research interests, Hewitt is interested in the development of new instrumentation and techniques for radio astronomy. And she's part of a collaboration of U.S., Australian, Indian, and New Zealand universities and research institutions that is building the Murchison Widefield Array in radio-quiet Western Australia.
