A gun designer with over 100 gun patents to his name, all of which were successfully sold and put into production. His first patent was for a rifle and sold for $8,000 during the late 1800s. Corrected for inflation, this would be enough to live off the interest in comfort. His most profitable design sold for an estimated $50,000. Many of his models are still in use today, such as the 1911 .45 ACP and the M2 machine gun, which is nearly unchanged beyond higher quality materials even to this day. Followed the engineering concept of KISS: Keep It Simple, Stupid.

He was a member of the LDS faith, also known as Mormons.

A John Brown is when you go to Harpers Ferry and jump in the water were the Shenendoah and the Potomic rivers meet each other. Swim out to the center of this intersection and take off all your clothes. Next, you jump out of the water and yell, "JOHN BROWN!" thus exposing yourself to the three states of Maryland, Virginia, and West Virginia all at the same time.
