Anna Peck Sill

Anna Peck Sill (born Aug. 9, 1816, Burlington, N.Y., U.S.—died June 18, 1889, Rockford, Ill.) was an American educator who opened and administered a girls’ school that would become Rockford College.

Sill began teaching school at the age of 20, and in 1843 she opened a seminary in Warsaw, New York. From 1846 to 1849 she headed the female department of the Cary Collegiate Institute in Oakfield, New York. For some years she had wavered between teaching and foreign missionary work; deciding at length in favour of teaching, in 1849 she accepted an invitation to open a girls’ school in Rockford. It was the hope of Rockford’s citizens that such a school would grow into the female seminary for which the Society for the Promotion of Collegiate and Theological Education in the West (founder of Beloit College) had already obtained a charter.

The school opened with 60 pupils, and in 1850 it was indeed chosen as the foundation for the seminary. Sill was confirmed as the principal of the Rockford Female Seminary in 1852. She exercised firm discipline over her students and was always primarily concerned with education as a tool of religion. Nonetheless, she maintained high academic standards and made the school a leader in women’s education in the Midwest. During the 1870s she began urging that the school be raised to collegiate status. Although it became a degree-granting institution in 1882, the name was not changed to Rockford College until 1892. Sill retired in 1884 and continued to live on the campus until her death.
