Janes & Leo

American architectural firm (1898–1911)

Janes & Leo was the New York-based architectural firm of Elisha Harris Janes and Richard Leopold Leo (1871/72 — 26 September 1911). From 1898 to 1911, the firm designed and built numerous Beaux-Arts residential structures in New York City, both richly detailed row houses and luxury apartment blocks during the building boom that constructed Manhattan's Upper West Side. Though neither Elisha Harris Janes nor Richard Leopold Leo ever studied at the École des Beaux-Arts in Paris, they worked within its traditions.2 Wikipedia text CC BY-SA 4.0
