Henry Schradieck (April 29, 1846 – May 25, 1918) was a German violinist, music pedagogue and composer. He was one of the foremost violin teachers of his day. He wrote a series of etude books for the violin which are still in common use today.
In need of a complete change, he left Leipzig for Cincinnati, Ohio, where he taught at the College of Music of Cincinnati, and also organized a symphony orchestra. In 1889 he took up his old position at Hamburg, besides teaching at the Hamburg Conservatory. Subsequently he returned to America, becoming a teacher in New York City, and in Philadelphia. He was a member of the Beta Chapter of Phi Mu Alpha Sinfonia Fraternity at Combs College of Music, initiated in either 1900 or 1906, and was active in the Fraternity's New York Alumni Club. In addition to writing pedagogic material for the violin in the way of studies and finger exercises, and earning the reputation of being one of the foremost violin teachers of that day, he also interested himself in matters connected with the making of violins.
