Professor Johan Gustav Wiborgh (c1839-1903)
1903 Obituary [1]
JOHAN GUSTAV WIBORGH died on March 16, 1903, at the age of sixty-four. He was one of the leading authorities on the metallurgy of iron in Sweden, having succeeded Richard Akerman as Professor of Metallurgy at the Stockholm School of Mines in 1892. He was the author of the standard handbook of the manufacture of pig iron in Sweden, and of numerous memoirs in Jernkontorets Annaler.
In 1886 he invented a charging apparatus for blast-furnaces, and from time to time devised numerous analytical methods. His method of determining sulphur in iron is widely used, and his volumetric carbon determination, his air pyrometer, and his thermophone met with general adoption. His most successful invention was his process for obtaining the fertiliser known as Wiborgh phosphate from phosphoric iron ores. He was not a member of the Iron and Steel Institute, but he contributed to its proceedings important papers in 1888 on his air pyrometer; in 1899 on the use of hot blast in the Bessemer process; and, at the Stockholm meeting in the same year, on the use of finely divided iron ore.
