Offenbach may refer to:
Offenbach is a Kreis (district) in the south of Hesse, Germany and is part of the Frankfurt/Rhine-Main Metropolitan Region. Neighbouring districts are Main-Kinzig, Aschaffenburg, Darmstadt-Dieburg, Groß-Gerau and the cities of Darmstadt, Frankfurt and Offenbach.
The district Offenbach was first formed in 1832 when the previous Landratsbezirke Langen (partially), Seligenstadt and Offenbach were merged. In 1852 the district area was enlarged in a westerly direction, while some of the southern part was moved into the district of Dieburg. In 1938 the area of the Frankfurt airport was added to the district, and the city Offenbach left the district to become a district-free city. However the seat of administration stayed in Offenbach.
After two minor changes in 1942 and 1974, in 1977 the district was given its current borders, and also the municipalities in the district were merged to 10 cities and 3 municipalities. In 2002, the capital of the district was moved from Offenbach to Dietzenbach.
Jacques Offenbach (French pronunciation: [ʒak ɔfɛnbak]; German: [ˈɔfn̩bax]; 20 June 1819 – 5 October 1880) was a German-born French composer, cellist and impresario of the romantic period. He is remembered for his nearly 100 operettas of the 1850s–1870s and his uncompleted opera The Tales of Hoffmann. He was a powerful influence on later composers of the operetta genre, particularly Johann Strauss, Jr. and Arthur Sullivan. His best-known works were continually revived during the 20th century, and many of his operettas continue to be staged in the 21st. The Tales of Hoffman remains part of the standard opera repertory.
Born in Cologne, the son of a synagogue cantor, Offenbach showed early musical talent. At the age of 14, he was accepted as a student at the Paris Conservatoire but found academic study unfulfilling and left after a year. From 1835 to 1855 he earned his living as a cellist, achieving international fame, and as a conductor. His ambition, however, was to compose comic pieces for the musical theatre. Finding the management of Paris's Opéra-Comique company uninterested in staging his works, in 1855 he leased a small theatre in the Champs-Élysées. There he presented a series of his own small-scale pieces, many of which became popular.
