Additional Notes

  • From the OHS Database Builders Listing editor, October 19, 2016. -

    William E. Haskell was the son of Charles S. Haskell, and brother of Charles E. Haskell. He invented the Haskell bass, an open pipe with this treatment is a bit longer than half its actual speaking length, with a compensating tube either inside or outside the pipe. Thus a genuine 16 foot tone can be generated by a pipe roughly nine feet in length. Haskell bases are still made today, and are often used to allow a long pipe to be placed under a low ceiling.

    William E. Haskell was born in Chicago, Illinois on November 29, 1865. The family was in Massachusetts, 1866-c.1879. The Haskell family moved to Philadelphia, Pennsylvania, c.1880 when Charles S. joined the the Roosevelt firm at the branch shop in Philadelphia, Pennsylvania. William joined his father working there starting at age 18. When his father established his own firm of C. S. Haskell in Philadelphia, c. 1888, William left Roosevelt and worked with his father, remaining there until c. 1900. He established his own firm, William E. Haskell Co. of Philadelphia, Pennsylvania, c. 1901. The firm was acquired by Estey Organ Co. of Brattleboro, Vermont, Haskell moved to Vermont and became superintendent of the Estey pipe organ division. He retired after suffering a stroke, c. 1923. William Haskell died May 13, 1927 in Vermont.

Some of our entries are names that might never appear on a nameplate or nameboard.
On the other hand, there are both individuals and firms who are responsible for conserving historic organs through location, or preserving the usefulness of pipe organs through rebuilding or making modifications to existing instruments. In these cases, we are proud to acknowledge their contributions to the ongoing artistic tradition of the pipe organ in America through individual entries in our online database.
