terms." According to the New Hampshire Historical Society, preceptresses of the academy were Sarah Fitz, 1816, Mary Knight, 1817–18, and Mary Adams, 1819. In 1821, Pinkerton stopped accepting young women, and the Adams Female Academy opened in Derry to educate young women. For the following years, the Scottish immigrants of Londonderry helped maintain the academy and also contributed funds for it. In 1853 the academy became coeducational with the erection of a ladies' boarding hall. In 1881, upon the death of John Morrison Pinkerton, son of Elder James, the academy received a second bequest. The Trustees used these funds to increase the number of instructors and to provide for an enlarged and advanced program of studies. Changes in the curriculum and the completion of the Pinkerton Building in 1887 allowed Pinkerton students to choose from a variety of college and non-college bound programs of studies. The funds were also used to buy a library and to erect a new school building. This was a large erection, but was completed quickly and the scenic landscape accented the beautiful new buildings. Pinkerton continued to function as an independent day and boarding school until 1948. In 1949, the academy entered into an agreement with the town of Derry that marked a significant turning point in the school's history. As a result of the service agreement, Pinkerton educated all high school aged students who lived in Derry. The town of Derry paid for the school's services on a per pupil tuition basis. Although Pinkerton maintained its private school status, the academy began to function as a comprehensive independent academy. In 1962, the town of Derry negotiated a long-term contractual agreement with Pinkerton Academy. The contract specified the terms and conditions under which Pinkerton's services were purchased. Over the next thirty years, additional communities (Chester, Hampstead, Auburn, Londonderry and Windham) signed service contracts with the academy. In response to the increased number of public school students attending Pinkerton, new facilities were built. Due to the changing needs and interests of this larger student population, Pinkerton once again developed new courses and fields of study while maintaining its existing college preparatory programs. In 1978, the citizens of Londonderry voted to end their tuition agreements with the academy and established Londonderry High School. Students from Windham also no longer attend Pinkerton Academy and now attend Windham High School which opened in 2009. In recent years several new
