Our History

Birken Manufacturing Company was founded by Louis B. Rogow in Hartford, Connecticut in 1943.

In 1952, Sidney Greenberg, who had both an aeronautical engineering degree and a law degree, joined the Company. Mr. Greenberg brought considerable experience from the aviation industry, having served in the Army Air Corps at Wright-Patterson Field and then at Hamilton Standard as an aero-dynamicist. He helped convert Birken from a gauge manufacturer to a manufacturer of precision jet-engine parts and sophisticated fuel control assemblies. The customer base through the 1980s included Pratt & Whitney, General Electric, Hamilton Standard, Raytheon and Lycoming.

By 1976, Mr. Greenberg had become President of Birken and had purchased a controlling interest in the company from Mr. Rogow. Incidentally, Mr. Rogow turned to philanthropy and spent a great deal of time in his later years promoting charitable giving and scholarship. He formed the Rogow-Birken Foundation which offered full scholarships to qualified students seeking engineering degrees. Today, the Foundation, which was renamed the Rogow Greenberg Foundation, provides annual scholarships to college students as well as grants to deserving charities.

Birken has been manufacturing precision components and assemblies since the early 1950's. Our product base has been expanded to include sophisticated sheet metal assemblies, gear box housings, and jet-engine vanes and struts. Our customer base has expanded to include among others, Pratt & Whitney Canada, ITP, MHI, Turbomeca, Magellan, Boeing, Rolls Royce and the U.S. Government.
