Karl Friedrich Wilhelm Mathy (March 17, 1807 – February 3, 1868), was a statesman from the Grand Duchy of Baden.
He studied law and politics at Heidelberg, and entered the Baden government department of finance in 1829.
His sympathy with the revolutionary ideas of 1830, expressed in his paper the Zeitgeist, cost him his appointment in 1834, and he made his way to Switzerland, where he contributed to the Jeune Suisse directed by Mazzini.
[1] In 1843 Mathy founded a publishing house in Heidelberg together with Friedrich Daniel Bassermann, that would later become known as Bassermann'sche Verlagsbuchhandlung.
[citation needed] He became one of the opposition leaders and in 1847 helped to found the Deutsche Zeitung, a paper which eventually did much to further the cause of German unity.
