# Dorothy Walcott Weeks

Dorothy Walcott Weeks (May 3, 1893 – June 4, 1990) was an American mathematician and physicist. Weeks was born in Philadelphia, Pennsylvania. She earned degrees from Wellesley College, the Massachusetts Institute of Technology, and Simmons College. Weeks was the first woman to receive a PhD in mathematics from the Massachusetts Institute of Technology.

## Early life

Dorothy Walcott Weeks was born on May 3, 1893, in Philadelphia, Pennsylvania, to Mary (nee Walcott) and Edward Mitchell Weeks, an engraver. Weeks was the second of three children, born after her older brother and before her younger sister Ruth. The family moved in 1900 from Cheltenham to Washington, D.C., where Weeks studied at Western High School.

## Education

Weeks graduated Phi Beta Kappa with a physics degree from Wellesley College in 1916, where she was also an active member of the Shakespeare society. After graduation, Weeks went on to work as a teacher, a statistical clerk, and an assistant at the National Bureau of Standards. In 1917 she became the third woman to work as a patent examiner at the US Patent Office.
In 1920 Weeks worked as a lecturer at the Massachusetts Institute of Technology and earned a master's degree in physics from that same institution in 1923. In 1924 she obtained a second master's degree, from the Prince School of Business at Simmons College, and became an employment supervisor for Jordan Marsh, the Boston department store. But by 1928, she had returned to academia, teaching physics at Wellesley College while working on her doctorate at the Massachusetts Institute of Technology.
In 1930, Weeks completed a PhD in theoretical physics from the mathematics department at the Massachusetts Institute of Technology. Her dissertation work was guided by Norbert Wiener and published in the Journal of Mathematics and Physics.

## Career

Following completion of graduate studies, Weeks developed and led the physics department at Wilson College in Chambersburg, Pennsylvania, from 1930 to 1956. Weeks left Wilson on sabbatical from 1943 to 1945, when she worked as a technical aide at the Office of Scientific Research and Development. Later, in 1949–50, Weeks was a Guggenheim Fellow at the Massachusetts Institute of Technology. While at Wilson in the 1940s, Weeks organized six summer sessions in which undergraduate women traveled to the Massachusetts Institute of Technology to work with George R. Harrison in the spectroscopy laboratory on compiling wavelength tables. Harrison referred to this as the "Charm School." Among the undergraduate students who participated was Katherine Sopka.
From 1956 through 1964, Weeks was a physicist at the Watertown Arsenal and the technical representative for the Committee on Radioactive Shielding. In 1964, she worked for the NASA supported Solar Satellite Project at the Harvard College Observatory. From 1966 to 1971 Weeks worked as a lecturer in physics at the Newton College of the Sacred Heart. She would continue to work at Harvard as a spectroscopist, studying solar satellites at the Harvard College Observatory until she retired in 1976 at the age of eighty-three.
Weeks died on June 4, 1990, at Newton-Wellesley Hospital in Newton, Massachusetts, due to a stroke.
