William Frishmuth - Wikipedia
William Frishmuth was born Johann Wilhelm Gottfried Frischmuth in 1830 in Coburg in the Duchy of Saxe-Coburg-Gotha (now Germany). Frishmuth studied with Friedrich Wöhler in Germany; aluminum is a metal not found in a pure state in nature, and the first patent for refining aluminum by electrolysis was granted to Wöhler. ...
