Who designed the Equitable Building and when was it built?

The Equitable Building, one of New York City's iconic skyscrapers, was designed by architect Ernest Graham and completed in 1915. This building is significant as it was one of the first to utilize the steel frame construction method, allowing for greater height and density in urban architecture. The design is notable for its distinctive, classic façade and for housing numerous businesses, reflecting the commercial trends of its time.

The other architects mentioned in the other choices were influential in their own rights, but none are associated with the Equitable Building. Frank Lloyd Wright is known for his organic architecture and designs such as Fallingwater. Louis Sullivan is celebrated for his work in the Chicago School of architecture and his influence on skyscraper design but did not design the Equitable Building. I.M. Pei, a modern architect known for works like the Louvre Pyramid, had no involvement in this particular building.
