was a German composer. He is chiefly remembered for his opera Martha, which was popular in the 19th century and the early part of the 20th.
Born in Teutendorf, in Mecklenburg, into an aristocratic family, Flotow was French-trained. Although he was intended for a diplomatic career, his father acceded to his wishes and he studied at the Conservatoire de Paris under Anton Reicha. During this time came under the influence of Auber, Rossini, Meyerbeer, Donizetti, Halévy, and later Gounod and Offenbach. These influences are reflected in his operas, where a distinctive French opéra comique flavour exists.
During the 1830 revolution he returned home, writing chamber music and operetta until it was safe to return to Paris. He completed his first opera in 1835, Pierre et Cathérine, but his breakthrough came with Le naufrage de la Méduse (1839), based on the wreck of the warship Méduse. The three-act romantic opera Alessandro Stradella of 1844 is recognized as one of Flotow's finer works. Martha was first staged in Vienna at the Theater am Kärntnertor on 25 November 1847, and soon became one of the best-loved of all his operas.
In 1848 revolution again drove Flotow home. Between 1856 and 1863 he served as Intendant of the court theatre at Schwerin. From 1863 he lived in either Paris or Vienna, and he had the satisfaction of seeing his operas mounted as far away as Saint Petersburg and Turin. He died in Darmstadt.
