1855 to 1926. He had just finished is last pistol design before his death. FN later introduced it as the Browning Hi-Power. I have a circa 1967 Hi-Power and a Colt series 80 as well as a few other Browning inspired firearms.

If I remember right, Browning died of a heart attack while working on the nearly complete over under superposed. This was at the great FN plant near Liege, Belgium.
Browning often had disputes with Winchester despite the fact that just about every gun they had made since buying the original single shot from him was a Browning design.
When Winchester balked at giving him a royalty for the automatic shotgun, he took it to Remington. In an odd occurrence, the President of Remington died of a heart attack while Browning was waiting to see him in his office.
Browning then took his shotgun to FN and received a welcome far better than he had from the American gunmakers. He also left them the design for a little .32 automatic pistol. The FN plant was nearly bankrupt and most of the machines idol. Before long they were turning out his .32 automatic pistol in the hundreds of thousands. These were the first guns to have “Browning” stamped on them. For a long time the word Browning was better known in Europe than America.
Of course FN did OK with the automatic shotgun too. For the rest of his life, Browning often had agreements where his designs sold in America were made by Colt and those sold in Europe were made by FN.
