From the OHS Database Builders Listing editor, April 5, 2016 —

A. David Moore established his firm in 1973 after a three year apprenticeship with the organ builder, C. B. Fisk. He lives and has his workshop on the large rural Vermont farm where he grew up. Here, with his associates, he designs and builds historically informed mechanical action organs. He has traveled extensively and studied some of the finest old (and some new) organs of Germany, France, the Netherlands, Denmark, Italy and England. He has a working knowledge of the treatises of Cliquot and Dom Bédos. Living and working in New England, he has acquired a knowledge of the 18th and 19th century New England builders.
