Sigismund Koelle

Sigismund Wilhelm Kölle (14 July 1820, Cleebronn- 18 February 1902, London) was a German missionary, and pioneer scholar of African languages.

After training in a missionary house in Basle, he transferred in 1845 to the Church Missionary Society based in London. From 1847 he was in Sierra Leone, where he taught at Fourah Bay College.

There he collected a large sample of linguistic material, some of it from freed slaves. His major work Polyglotta Africana from 1854 began the serious study by European scholars of a large range of African languages

.45 Schofield

The .45 Schofield or .45 Smith & Wesson is a revolver cartridge developed by Smith & Wesson for their S&W Model 3 American top-break revolver. It is similar to the .45 Colt round though shorter and with a slightly larger rim, and will generally work in revolvers chambered for that cartridge. US government arsenals supplied .45 Schofield cartridges for the Schofield revolver and the Colt Army revolver to simplify their armament needs. 45 Colt cartridges cannot be used in .45 Schofield firearms, since the .45 Colt is a longer cartridge.

History

This cartridge was originally designed as a black powder round. The Schofield revolver (a variant of the Smith & Wesson Model 3) was patented in the USA on 20 June 1871 and 22 April 1873 by Smith & Wesson. It was a Smith & Wesson Model 3 that was modified by Major George Schofield to make it easier for a cavalryman to reload while riding. While the Colt 45 had more power, the speed at which a cavalryman could reload a Schofield was less than 30 seconds, half of the time for a Colt 45. By 1879, the U. S. Army had purchased 8,285 of the revolvers. Due to its reduced power and recoil compared to the Colt .45, it was easier to shoot accurately, yet still retained effective stopping power on the battlefield. It became the standard cartridge of the Army, though the Colt 1873 still was the main issue side arm of the Army.

.500 S&W Magnum

The .500 S&W Magnum (12.7×41mmSR) is a fifty-caliber semi-rimmed handgun cartridge developed by Cor-Bon in partnership with the Smith & Wesson "X-Gun" engineering team for use in the Smith & Wesson Model 500 X-frame revolver and introduced in February 2003 at the SHOT show. Its primary design purpose was as a hunting handgun cartridge capable of taking all North American game species.

Cartridge history

Smith & Wesson had been at the forefront when developing powerful handgun cartridges such as the .357 S&W Magnum and the .44 Remington Magnum. However, since 1960 the company’s .44 Remington Magnum, which it had developed in partnership with Remington, was eclipsed by the .454 Casull. Since then, several other more powerful cartridges had been developed by Action Arms, Linebaugh, Ruger, Wildey, and Winchester for repeating handguns.

In 1971 Smith & Wesson had experienced a dramatic surge in orders for their Model 29 revolver in the .44 Magnum cartridge with which S&W production was not able to keep up. Available Model 29 revolvers were being sold for two to three times the suggested retail price, due to the low supply and high demand for the revolver. This surge in demand was due to the Dirty Harry movie, where the Model 29 revolver was billed as the most powerful revolver (The .454 Casull designed in 1955 would not be in commercial production until the 21st century). With the entry of the .500 S&W Magnum and the Model 500 revolver, Smith & Wesson recaptured the title of the most powerful handgun, and with it an increase in sales.
