Henry Schradieck was a violinist, music educator, and composer from Germany. He was regarded as one of the best violin teachers of his day. He wrote a collection of violin etude books that are still widely used today.

He was born in Hamburg, where his father taught him to play the violin, and he made his first public appearance at the age of six. He earned first prize at the Royal Conservatory of Brussels, where he trained under Hubert Léonard. He then moved to Leipzig, where he studied under Ferdinand David. In 1863, he made his debut as a soloist at Bremen's Reinthaler concerts. He went to Moscow as a violin professor the following year. In 1868, Schradieck returned to Hamburg to fill the vacancy left by Leopold Auer as conductor of the Philharmonic Society. He became the Leipzig Gewandhaus Ensemble, lecturer at the Leipzig Conservatory, and conductor of the theater orchestra after six years.

He left Leipzig for Cincinnati, Ohio, searching for a total transition, where he taught at the Cincinnati College of Music and assembled a symphony orchestra. In addition to teaching at the Hamburg Conservatory, he resumed his old job in Hamburg in 1889. He then moved to America and worked as an instructor in New York City and Philadelphia. He was a founder of the Phi Mu Alpha Sinfonia Fraternity's Beta chapter at Combs College of Music and was involved in the Fraternity's New York Alumni Club. He was initiated in either 1900 or 1906. He was engaged in subjects related to the production of violins, writing educational content for the violin in the form of studies and finger exercises, and gaining the distinction of being one of the leading violin instructors of the day.
