Biography

Edwin I. Groff patented the first commercially successful automatic pretzel twisting machine and founded Reading Pretzel Machinery, the forerunner of Reading Baking Systems, in 1947.

His machine was designed to manufacture spiral pretzels very uniform and quickly, which results in rapid overall production.

He is the son of Edwin C. Groff and Alberta Haas.

He married Kathryn S. Trostle [1] who died in March 1997, and is survived by a son, E. Terry.
