Browning's father
Jonathan—who was among the thousands of
pioneers of
the Church of Jesus Christ of Latter-day Saints who made an exodus from
Nauvoo, Illinois, to
Utah—established a
gunsmith shop in Ogden in 1852. As was common in the Latter-day Saint community at the time, Jonathan Browning was a
polygamist, having taken three wives. He fathered 22 children, including John Moses, and raised two stepdaughters with his wife Elizabeth Caroline Clark. Browning worked in his father's Ogden shop from the age of seven, where he was taught basic engineering and manufacturing principles, and encouraged to experiment with new concepts. He developed his first rifle, a
single-shot falling block action design while he was still his father's apprentice, then, in 1878, in partnership with his younger brother, co-founded John Moses and Matthew Sandefur Browning Company, later renamed
Browning Arms Company. The company began producing the brothers' designs and other non-military firearms. By 1882, the company employed John and Matthew's half-brothers Jonathan (1859–1939), Thomas (1860–1943), William (1862–1919), and George (1866–1948). Like his father, Browning was a member of The Church of Jesus Christ of Latter-day Saints, and served a two-year
mission in
Georgia beginning on March 28, 1887. He married Rachel Theresa Child (September 14, 1860 – September 30, 1934) on April 10, 1879, in Ogden, Weber County, Utah Territory, and the couple had 10 children, two of whom died in infancy. == Firearm designs ==
