How it Started

The Williams School opened in 1891 as Williams Memorial Institute (WMI).

The School was privately endowed by a bequest from the estate of founder Harriet Peck Williams as a memorial to her son, Thomas W. Williams II. Since then it has grown and expanded to serve students from the greater New London and Middlesex Counties for over 130 years.

The School was created as a high school for “the promotion and advancement of female education” at a time when few saw it as a priority. WMI served as the high school for girls of New London and several surrounding towns operating on Broad Street in New London which now operates as one of the courthouses in the Connecticut State Judicial system, listed on the register of Historic Buildings of Connecticut.

Growth & Change

Growth and change for the School was accelerated in the post-war era when the academic program shifted to a college preparatory liberal arts curriculum. In 1954, the School moved from Broad Street to its present location on the Connecticut College campus. Other major changes for Williams were the addition of a middle school (grades 7 & 8) in 1955.

In 1971 the School became coeducational.
