Toscha Seidel was a Russian violin virtuoso.
Seidel was born in Odessa on November 17, 1899, to a Jewish family. A student of Leopold Auer in St. Petersburg, Seidel became known for a lush, romantic tone and unique and free rubato. In the 1930s he emigrated to the United States. Before making his way to Hollywood where he made a career in the studios of motion pictures, he had a show on CBS radio called The Toscha Seidel Program; he was also that radio network's musical director. He was featured (as soloist) in several Hollywood productions, including the movies Intermezzo, Melody for Three, and even The Wizard of Oz. He was also an avid chess player (like Mischa Elman). In 1922, George Gershwin wrote a song about him and his fellow Russian-Jewish virtuoso violinists called, "Mischa, Jascha, Toscha, Sascha."
Seidel had a weekly broadcast on the CBS radio network in the 1930s.
In 1934 Seidel gave violin instruction to Albert Einstein, and received a sketch in return, reportedly diagramming length contraction of his theory of relativity.
He died on November 15, 1962.
