Architect. Initially a watch engraver, he was largely self-taught in architecture. He became a prominent designer and promoter of cast-iron architecture as fireproof, efficient, and transportable. He built structures in New York City, where several survive, as well as in Charleston, South Carolina and the District of Columbia.  Four of his five surviving buildings are in New York City and have landmark status.
