Lange, Gustav 08/13/1830 - 07/20/1889

Wikipedia:
Gustav Lange (* August 13, 1830 in Schwerstedt; † July 20, 1889 in Wernigerode) was a German composer of the Romantic period.
Gustav Lange was taught as a child piano and organ by his father. He later studied piano, organ, basso continuo, and composition at the Erfurt Conservatory. Encouraged by his successes as a composer in the 1860s, Lange composed close to 500 piano works, including fantasies, marches, polonaises, mazurkas, and transcriptions of famous works by Wolfgang Amadeus Mozart, Anton Rubinstein, and others. Most of his pieces can be categorized as salon music and thus do not have a high degree of difficulty. The piano piece ''Edelweiß'' (op. 31) and the ''Blumenlied'' (op. 39) are the composer's best known works today.
