Fyodor Stein (German: Theodor Stein; 1819–1893) was a pianist and music teacher. He was born in Altona, Germany, on 16 March 1819. His musical abilities appeared very early, and from the age of eight he traveled with his father, giving concerts in German cities.
His talent attracted the attention of Clara Schumann, who published an article about him in a music newspaper. Stein completed his musical education in Copenhagen. At the age of seventeen he came to Russia and gave several concerts in Saint Petersburg.
Stein wanted to settle in Saint Petersburg, but the unfavorable climate prevented this, and he moved to Reval. He lived in Reval for thirty years, though he occasionally left to give concerts elsewhere. In 1846–1847 he lived in Stockholm, where he organized subscription concerts devoted mainly to chamber music. Through his efforts, a musical society with annual subscription concerts was created in Reval.
He also performed with great success in Hamburg and Paris. In 1872 he was invited to join the faculty of the Saint Petersburg Conservatory as one of its professors, and from that time he lived in Saint Petersburg until his death. He appeared there many times in symphonic and chamber concerts and was mentioned as a talented performer.
Stein died on 24 February 1893 in Saint Petersburg and was buried at the Volkovo Lutheran Cemetery.
