Hammerman Brothers was founded in New York in 1946 by Benjamin, Hyman and Bernard Hammerman. The three brothers had all recently returned from war and decided to go into business together as before the war they all worked separately in jewelry in the bowery district in NYC. Upon their return though they set up a jewelry manufacturing company. Over time they expanded their business vertically with the introduction of the Kelman Casting Company and the Bermont Diamond Company. They were attempting to control as much of the process as they could in house. This led them to create watch bracelets for companies like Bulova (they even created the bracelet for Dwight D Eisenhowers Bulova!
