Sergei Stadler is a Russian violinist, teacher, and conductor born (in Saint Petersburg) on May 20, 1962. Although he took first prize (alongside Victoria Mullova) in the famous Tchaikovsky Competition (in 1982) and the Grand Prize in the Jacques Thibaud Competition (in 1980 – one source has it as 1979), he is not as well-known as one might expect. However, he has developed a very successful career in Russia and Europe, having played in most of the important concert venues. He is also an opera conductor. Stadler actually began his music studies in piano, taking lessons from his parents, although his father was a professional violinist. He entered the Saint Petersburg Conservatory at age 12. He studied violin with Boris Sergeyev in Leningrad (Saint Petersburg.) He also later studied with Mikhail Vaiman, Victor Tretyakov, Leonid Kogan, and David Oistrakh. From 1984 to 1989 he taught at the Saint Petersburg Conservatory. In his career as a teacher, he has conducted master classes in Europe and the far east. He has also founded several performing organizations - the Hermitage Music Academy, and the New Saint Petersburg Symphony are among them. He has about 30 CDs to his credit – one source says 50 – including one with all Beethoven Sonatas, accompanied by his sister Julia. Here is one video of his on YouTube.
