Julius Fröbel

Carl Ferdinand Julius Fröbel (16 July 1805 – 7 November 1893) was a German geologist and mineralogist, journalist, and democratic revolutionary already during the Vormärz era. He was active in Germany, Switzerland, the United States and South America at different times in his life.

He was born in the Thuringian village of Griesheim (today part of the Ilmtal municipality), the son of pastor Johann Michael Christoph Fröbel (d. 1813) and his wife Christiane Sopie. He attended the educational institute of his uncle Friedrich Fröbel, the founder of the kindergarten system, and continued his studies of natural sciences at the universities of Jena, Munich, and Berlin. By the agency of Alexander von Humboldt, Fröbel took up a teaching position in Zürich in 1833 and became a naturalized citizen of Switzerland. From 1836, he taught mineralogy at the University of Zürich. In 1838 he married his first wife Kleophea, née Zeller.

Upon the reactionary Züriputsch in 1839, he joined the radical party, and edited Der schweizerische Republikaner (The Swiss Republican) for them. In 1840/1841, he established a publishing house (Literarisches Comptoir) at Zurich. He issued several scientific works and many political pamphlets, many of which were suppressed in the states of the German Confederation, among them writings by Bruno Bauer, Friedrich Engels, Ludwig Feuerbach, Arnold Ruge, Friedrich Wilhelm Schulz, and David Strauss, as well as poems by Georg Herwegh, Hoffmann von Fallersleben and Gottfried Keller.
