.50 caliber firearms have been made since the early days of muzzleloaders. The original maker of a gun in this caliber is not known. Given that .50 is 1/2 inch, a convenient measurement, .50 caliber muzzleloaders are very common. There are several .50 caliber cartridges in existence. They range from the .50BMG used in heavy machine guns and long range sniper rifles to the .50 Beowulf used in AR type rifles to .50 AE, .50 GI and .500 S&W used in handguns. These cartridges were invented by different people at different times.
