History[edit | edit source]
Born in Germany to German parents, Heide was noted as being a skilled machinist in his youth. Heide emigrated to the United States in 1927, with the rest of his family following suit the next year. He changed his name to Hyde at some point later.
Hyde was first a machinist and foreman at Griffin & Howe. He later worked for General Motors, where he became an employee for the Guide Lamp division and designed the M3 submachine gun with Fred Sampson and René Studler. After this stint at Guide Lamp, Hyde moved to become the chief designer at the Inland Division of General Motors.
After working at General Motors, Hyde worked for Bendix Aviation for a time, designing the Hyde-Bendix carbine; the weapon never went into production. Hyde developed another carbine in 1944, but was also unsuccessful.
