Father John McElroy

May 1782 - John Mc Elroy, founder of St. John’s Literary Institution, is born in Euniskillen, Ireland. He immigrated to America at the age of twenty-one, settling first in Baltimore, Maryland, then in Washington, D.C., where he entered the Jesuit Order at Georgetown.

Circa 1787-1803 - Large, elegant mansion, later known as Prospect Hall and future site of St. John’s Literary Institution was constructed on Red Hill.

1829 - Father McElroy founds Saint John's in Frederick with the Society of Jesus (who also founded the first free school for black children in Washington D.C., and founded Boston College in 1865). Charter of St. John's Literary Institution is obtained from Maryland State Legislature.

1915 - St. John's Literary Institution becomes coeducational, and the School Sisters of Notre Dame help staff the parish school.

1958 - St. John's Literary Institution moves from downtown Frederick to the Prospect Hall property.

1972 - The School Sisters of Notre Dame were no longer able to staff the school, so a group of dedicated parents and parishioners pool their energies and resources to keep the school open. St. John's opens as the first independent Catholic School in Maryland.

1979 - Prospect Hall Mansion is placed on the National Register of Historic Places. A Sesquicentennial Celebration Ball is held for St. John's Literary Institution.
