Metallurgy was another important part of Katowice's economy. In 1863 a dozen zinc metallurgy facilities were reported in Katowice, with "Wilhelmina" (founded in 1834) being the largest. In early 1900s, "Wilhelmina" (later renamed "Huta Metali Niezależnych Szopienice") was enlarged and became the largest Silesian producer of non-ferrous metals and world's largest producer of cadmium. Two major steelworks existed in the city: "Huta Baildon", established in 1823 by the Scottish engineer and industrialist John Baildon (declared bankruptcy in 2001), and "Huta Ferrum", established in 1874 and operating to this date in limited capacity.
