Caleb Warner

Caleb Warner (born 1922), son of Langdon Warner (Harvard professor who studied the Silk Road and was purportedly the model for Hollywood's Indiana Jones). Marine engineer and acoustical turnkey engineer, classical trumpeter, owner of the Instrument Guild. Designed and produced the Baldwin Spinet Electric harpsichord which was used on the Beatle's "Because", and for the brief postlude on the Who's "Live at Leeds" album, and used by many others. Also designed and produced solid body rehearsal harpsichords and dulcimers.

Actually, the harpsichords and dulcimers were not solid body; they were of fairly conventional hollow geometry but were made of fiberglass. For the harpsichord in particular, the stronger and more stable material permitted a fairly small instrument to have a bigger bass sound for its size than a wood instrument could have and to be far more stable in its tuning than a wood harpsichord. I knew them under the name "Instrument Guild." It is possible that solid body instruments were produced, but I never saw them or heard Caleb speak of them.
