Frederick J. Osterling

Who was Frederick J. Osterling?

Frederick John Osterling was an American architect, practicing in Pittsburgh from 1888.

Osterling received his training in the office of Joseph Stillburg. Following a period of European travel, he launched his own practice in 1888. During his career he designed many prominent Pittsburgh buildings, such as the Union Trust Building. According to Martin Aurand, Architecture Librarian at Carnegie Mellon University in Pittsburgh, Osterling's practice faltered after controversy relating to his anticipated alteration to the landmark H.H. Richardson Allegheny County Courthouse and a public lawsuit filed by the industrialist Henry Clay Frick. Osterling's studio was in a building he designed himself in 1917 at 228 Isabella Street in Pittsburgh's North Shore neighborhood.
