John A. Dempwolf (1848–1926) was a German-born American architect practicing in York, Pennsylvania from 1876 until his death in 1926.
[2] He was apprenticed to local carpenter William Gotwalt to learn the trade and worked in a planing mill as a drafter.
Recognizing his brother's talent for design, at his encouragement Reinhardt traveled to Paris, where he was admitted to the École des Beaux-Arts in 1886.
During John A. Dempwolf's lifetime, his office is documented as having designed at least 500 buildings in Pennsylvania, Maryland and elsewhere.
Major works included buildings at Gettysburg College and the Harrisburg State Hospital.
