Offenbach was born Jacob or Jakob Offenbach to a Jewish family, in the German city of Cologne, which was then a part of Prussia. His birthplace in the Großen Griechenmarkt was a short distance from the square that is now named after him, the Offenbachplatz. He was the second son and the seventh of ten children of Isaac Juda Offenbach né Eberst (1779–1850) and his wife Marianne, née Rindskopf (c. 1783–1840). Isaac, who came from a musical family, had abandoned his original trade as a bookbinder and earned an itinerant living as a cantor in synagogues and playing the violin in cafés. He was generally known as "der Offenbacher", after his native town, Offenbach am Main, and in 1808 he officially adopted Offenbach as a surname. In 1816 he settled in Cologne, where he became established as a teacher, giving lessons in singing, violin, flute and guitar, and composing both religious and secular music.
