Hyman Lehman

Hyman S. Lebman aka Hyman S. Lehman or Hymie Lebman (1903–1990) was a San Antonio, Texas, gunsmith and leather worker. Working out of his saddlery shop and gun store at 111 South Flores Street in San Antonio, Lebman provided specialized and custom made weaponry to several well-known bank robbers and outlaws during the Great Depression.

United States court documents refer to Lehman as Hyman Saul Lebman. Lebman's own son, Marvin Lebman, who worked with his father in his gun and saddlery shop from 1937 to 1976, spells his father's name as Lebman.

Born into a prominent Texas family, Hyman Saul Lebman became an accomplished gunsmith and leather worker. During the 1930s, he opened a gun store and saddlery shop at 111 S. Flores Street in San Antonio. Lebman was frequently asked by his customers to secure unusual weapons, including the Thompson submachine gun built by Colt, which at the time could be ordered through the mail and purchased at gun or hardware stores. Soon, Lehman began customizing Colt pistols and other small arms, including conversion into fully automatic weapons. One of his Lebman's specialties was the "Baby machine gun", a Colt Model 1911 semi-automatic pistol in .45 Automatic or .38 Super caliber, converted to full-auto fire. This machine pistol featured an oversized ammunition magazine, a muzzle brake or compensator, and a fore grip adapted from the more familiar Thompson submachine gun. Lebman's son Marvin described his father's development of the Colt "machine pistol" concept:

Lebman continued to sell his machine pistols and other automatic weapons until the passage of the National Firearms Act in 1934. When Chicago bootlegger Roger "The Terrible" Touhy was arrested in Wisconsin on July 19, 1933, one of Lebman's "baby machine guns" was found in his car. Pretty Boy Floyd, John Dillinger, and several known associates of the Dillinger gang were also customers. A full-auto Lebman Colt belonging to Dillinger was found at one of his hideouts in St. Paul, Minnesota, on March 31, 1934, as well as leaving behind at the Little Bohemia Lodge three weeks later.
