In 1914, after undergraduate studies in architecture at Princeton, Rolf Bauhan and his roommate, Hobey (Hobert) Baker, motorcycled through Europe and joined the aviation section of the army's signal corps in World War I.
Following the war, Bauhan earned his master's degree at Princeton and was chosen to direct the restoration of Europe's badly damaged cathedrals. Bauhan was instrumental in establishing the School of Architecture at Princeton University. As designer of approximately 300 homes in the Princeton and New Hope areas, mainly in the Georgian and colonial styles, Bauhan was said to have "built half of Princeton."
He also served as a consultant on the restoration of Williamsburg. He was responsible for many buildings at the Hun School and Solebury School, an he restored Princeton's Morven House, residence of New Jersey's governors. Bauhan also designed the Solebury Township Building, the Union Paper Mills office building, and the Robert Charles Home on River Road. In 1954, Bauhan designed buildings for the Princeton University Housing Corporation, an experimental housing project for faculty members. Bauhan painted in watercolors, primarily as a hobby.
