George J. Hyde Sr. (born Heide; January 4, 1888 – December 1963) was a German-born American machinist, gunsmith and gun designer best known for his submachine guns. He was born in Apfingen, Germany. Already a skilled machinist, he immigrated to the United States in 1927. His family followed the next year.

(The latter was an early semi-custom maker of rifles chambered in .257 Roberts.)
