George A. Gregerson was bom in Laurvig, Norway in 1845. When he was nine years old his family emigrated and located in Walworth County, Wisconsin. His father and mother died the same month, leaving four children, of whom George was the youngest.

In 1861, he moved to Rochester, Minnesota, but after two years, he retumed to Wisconsin to learn the harness trade. He then retumed to Rochester and commenced business. Gregerson soon carried a large stock and employed a large force of men. Part of the reason for his success was his investing ability. Gregerson was the inventor of a patent blinder for bridles (1880), neck-yoke ends (1883), and a machine for braiding whips. These articles were reportedly widely sold and brought him money. He died on 13 October 1914 at the Olmstead County Hospital.

Gregerson married Anna M. Johnson, a native of Norway, in 1868. They had five children: Frederic O., Amelia M., Lulu E., Flora A., and Lawrence E. There are a few items pertaining to Frederic in the in the Gregerson Papers. Frederic moved to Fargo, North Dakota sometime around 1913, raised a family and died there on 27 January 1939.
