Biographical Text

Theophilus Andrew Wylie III, who went by “Theo,” was born on 10 March 1878 to Sarah Seabrook Mitchell and Samuel Brown Wylie III. He and his family lived in the Wylie House until he was seven years old, when they moved to another house in Bloomington and then to Beaver Falls, Pennsylvania. Theo’s father died suddenly five years later, and Theo moved back into the Wylie House with his grieving mother and siblings. When Theo was a teenager, he moved to Philadelphia, Pennsylvania, to attend St. Luke’s, a private boys’ school. In 1899, Theo's mother, who had moved with him to the northeast, passed away. At the time, Theo was in his final semester in college in Boston, perhaps at the Massachusetts Normal Art School. On 14 November 1906, he married Maude George (1879-), a writer and dance instructor, but the couple divorced by 1920. Theo served as a corporal in the U.S. Army during World War I. He lived with his cousin Marie Boisen Bradley and her family in Arlington, Massachusetts, upon his return to the United States. In 1923, he moved to Manchester, New Hampshire. He married Agnes Evans (1897-1966) on 1 September 1934. Over the course of his career, Theo worked in photography and engraving at Phelps Publishing Company in Boston; Gillespie & Wylie in Arlington, Massachusetts; the New Hampshire Photo Engraving Company in Manchester, NH; and Nashua Gummed & Coated Paper Company in Nashua, NH. Theo died on 26 January 1960 and is buried at Pine Grove Cemetery in Northwood, New Hampshire.
