Sperry Gyroscope Company Building, ca. 1939.

Designed by Frank Helmle and constructed in 1915-1916, the Sperry Gyroscope Company Building (today called the Howard Building) is a reinforced concrete industrial building. The Gyroscope Company was founded in 1910 by Elmer Ambrose. The gyroscope was an important new navigating tool for maritime and air travel. The location of the factory was purposeful, with the proximity to the Manhattan Bridge allowing the building to get sunlight from all directions. Built during the First World War, but prior to Americans entrance to the fighting, the factory manufactured items that aided in ship, plane, and torpedo navigation, actions that the U.S. felt they would likely be involved with soon enough.

Despite further inventions and technological advances in the following decades, the Sperry Gyroscope Company was broken up by the mid century though mergers and legal actions. Today the Howard Building's largest major tenant is New York City College of Technology.
