John Hollway
John M. Hollway was an English metallurgist and chemist who, in the 1870s, unsuccessfully tried out smelting and refining of copper using a converter based on the Bessemer process.
Although his attempts failed, conceding to the French engineers Pierre Manhès and, the honor of the invention of the Manhès-David process in 1880, the abundant communication he made on his failures constitute a significant contribution to the development and perfecting their process.
