Blohm & Voss was founded on 5 April 1877, by Hermann Blohm and Ernst Voss (or Voß) as a general partnership, to build steel-hulled ships. It established a shipyard on the island of Kuhwerder, near the Free and Hanseatic City of Hamburg, covering 15,000 m2 (160,000 sq ft) with 250 m (820 ft) of water frontage and three building berths, two suitable for ships of up to 100 m (330 ft) length. The company name was shown with the ampersand, as B&V, until 1955.
