William E. Haskell was an American organ-builder and inventor born on November 29, 1865, in Chicago, Illinois.
[1] His father, Charles S. Haskell, was also an organ-builder employed by the Roosevelt organ company, located in Philadelphia.
This organ-building firm was later acquired by Estey Organ Co., and Haskell became superintendent of the Estey pipe organ division, which was located in Vermont.
It is used in spaces where it is too small for a full-length pipe to be feasible.
[3] He also invented several reedless orchestral imitation stops, such as the clarinet, oboe, and saxophone, whose advantage lay in the fact that they would stay in tune with the other flue stops.
