Theodor Hosemann was born on September 24, 1807, in Brandenburg an der Havel. Hosemann went to Berlin in 1828 after completing an apprenticeship as a lithographer and drawer and attending the Academy of Art in Düsseldorf. In Berlin, he published his first illustrations in children's books, books for youths and his humoristic drawings in the color papers by George Gropius beginning in 1830. This made Hosemann into a sought after illustrator for other publishing houses as well. He became a professor at the Berlin Academy in 1857 and was appointed a member of the same in 1860. During his teaching tenure in 1874, Heinrich Zille was also a student of his. Aside from his illustrations in children's and youth books, Hoseman created many illustrations for such literary works as Gottfried August Bürger's "Münchhausen," E. T. A. Hoffmann's "Gesammelte Schriften" ("Collected Writings"), Eugène Sues "Die Geheimnisse von Paris" ("The Secrets of Paris"), and the works of Ernst Moritz von Arndt and Joseph von Eichendorff. He also gained popularity for his intelligently ironic and well-drawn representations of everyday scenes of Biedermeier Berlin in series such as "Berlin wie es ist - und trinkt" ("Berlin, how it is - and drinks") or "Buntes Berlin" ("Berlin in Color"). Hosemann is a typical representative of the realistic Biedermeier style in Berlin of the 19th century with his feather and chalk lithographs. Hosemann died October 15, 1875, in Berlin.
