Since sororities assist so much with the personal and professional development of young women, it comes as no surprise that some of the most accomplished women were also in a sorority in college. These five women were sisters of Sigma Kappa in their college days and went on to pursue ambitious careers and break down barriers for women in their fields.

1. Susan Eisenhower

If this name sounds familiar, it's because she is the granddaughter of former President Dwight Eisenhower. But what's more, Susan Eisenhower is the CEO and Chairman of consulting company The Eisenhower Group in Washington D.C., has worked as a policy analyst, served on committees for the Department of Energy, and is an expert on relations between the Russian Federation and the USA. And, she was a member of the Epsilon Epsilon chapter Sigma Kappa at the University of Georgia.

2. Dr. Margaret Rhea Seddon

It doesn't get much more boss than being an astronaut. Margaret Rhea Seddon, a sister from the Lambda chapter at the University of California, Berkeley, is a retired astronaut who was selected for NASA's first group of astronauts to include women. She traveled into space on three different missions, after she graduated from med school.

3. Margaret Chase Smith

The first female U.S. senator was also a member of Sigma Kappa's Alpha chapter at Colby College. In addition, Margaret Chase Smith was also the first woman to sit in both houses of the United States Congress.

4. Anna McCune Harper

Anna Harper was a professional tennis player and Wimbledon champion. She was a member of the Lambda chapter at the University of California Berkeley, and in 1939, she served as National President for Sigma Kappa.
