A detailed survey and catalogue of the life and works of the English organ builder Samuel Green (1740-1796). A short biographical survey traces Green's career to the period when he established himself as the foremost English builder of organs of the late 18th century. This is followed by a detailed account of the design and constructional method of his chamber instruments and church organs. A chronological survey of his entire output gives the specification and history of each instrument and a reassessment of earlier sources. The text is illustrated with photographs and line drawings showing the characteristic features of Green's organ construction.
