Friedrich Ruthardt
Friedrich Ruthardt was a German oboist and composer. He played in the Stuttgart court orchestra, and composed chorales as well as pieces for the oboe and the zither. One of the best-known 19th-century oboe concertos, by Bernhard Molique, was likely written for Ruthardt, and first performed at Stuttgart in 1829.
Two of his sons were also musicians: Julius Ruthardt, a violinist; and Adolf Ruthardt, a music teacher and composer.
