Pierre-Émile Martin

Pierre-Émile Martin (born August 18, 1824 in Bourges , † May 23, 1915 in Fourchambault ) was a French metallurgical engineer .

François Marie Emile Martin (1794–1871) and his son Pierre ran a small iron and steel works in Sireuil near Angoulême ( Charente , western France). Above all, hard rifle steel was produced for the manufacture of Chassepot rifles using a process by Réaumur (1722) from pig iron and steel scrap.

After initial failures, they succeeded, in collaboration with the German engineer Carl Wilhelm Siemens , in developing a new steel furnace with regenerative combustion that was able to melt pig iron and scrap together. From April 8, 1864, this hearth furnace delivered one ton of so-called “hearth steel” per batch. In 1865 he registered a patent for his steel furnace.

The steelmaking process known as the Siemens-Martin process replaced the problematic Bessemer process .

Siemens and Martin got into a dispute over the rights to the invention, whereby Martin went bankrupt in 1893 . He became impoverished and forgotten. He lived in Paris and received financial support in 1910 through a donation from the European iron industry.
