Theodore Oesten (also Theodor in German) (not Theodore in German) (December 31, 1813 – March 16, 1870) was a German composer, musician, and music teacher.^[1]

Oesten was born in Berlin. He learned to play wind and string instruments from the Stadtmusikus in Fürstenwalde (a small town outside Berlin). At the age of nineteen he studied composition with Böhmer, Carl Friedrich Rungenhagen, G. A. Schneider and August Wilhelm Bach in Berlin. Oesten is perhaps best known for his easy to play piano compositions, including transcriptions of operatic works, written in the sentimental style of his day. He died in his native city of Berlin. His son Max Oesten also became a composer.^[1]
