Sikorsky, a lawyer from Unionville, Conn., will talk about the life of his late father, Igor Sikorsky Sr., who left Russia during the Communist revolution and ultimately moved to America. He built his first airplane nearly 100 years ago, and went on to design both fixed-wing planes and helicopters. It is the latter, of course, that made him famous, and Sikorsky Aircraft in Stratford remains one of the world’s premier helicopter manufacturers.

Sikorsky Jr. also has authored a book called the “Sikorsky Lindbergh Connection,” about the relationship between his father and the great aviator Charles Lindbergh. The Seymour Historical Society is located at 59 West Street, near the Trinity Episcopal Church. There is no admission charge for the program, and cold drinks will be available. The museum will remain open after the presentation for anyone who would like to view the exhibits.
