Purpose: Sigma Kappa fosters lifelong connection in sisterhood while being true to our founding as an intellectual and social women's sorority. Through mutual support and respect, we inspire all members to lead a life of purpose.

Sigma Kappa was founded at Colby College in Waterville, Maine, during a time when women were only beginning to gain equal access to higher education. In 1874, five pioneering women, Mary Caffrey Low, Elizabeth Gorham Hoag, Ida Fuller, Frances Mann and Louise Helen Coburn, came together to create a community centered on friendship, scholarship and shared values. On November 9, 1874, their petition to establish Sigma Kappa was officially approved, a date we now celebrate as Founders’ Day.

The Theta Lambda Chapter of Sigma Kappa was chartered at the Massachusetts Institute of Technology on February 11, 1989. Since then, generations of MIT Sigma Kappas have built a strong and supportive sisterhood while contributing to the Institute and greater Boston community. Today, Theta Lambda is home to more than one hundred members and continues to bring Sigma Kappa’s values to life at MIT.
