David Cobb Rosebrook (January 19, 1874 – March 31, 1937) was an American cornet soloist, trumpeter, composer and conductor.

[2] David Rosebrook began his career as a cornet player in New York and Boston.

When Henry Ohlmeyer took his band on a tour of West Coast cities during the early summer of 1910, Rosebrook was his cornet soloist and Herbert L. Clarke was the "special soloist".

[3] In 1930, Rosebrook returned to the San Francisco Symphony as second trumpet, and he remained there in that position through 1935 until the orchestra was suspended.

After playing for about 5 weeks, he became ill and returned home to San Francisco.
