John Broadwood (6 October 1732 – 17 July 1812) was the Scottish founder of the piano manufacturer Broadwood and Sons.


Broadwood was born 6 October 1732 and christened 15 Oct 1732 at St Helens, Cockburnspath in Berwickshire, and grew up in Oldhamstocks, East Lothian. He inherited his father James Broadwood's (b1697 Oldhamstocks) profession, that of a wright or carpenter/joiner, and as a young man walked from Oldhamstocks to London, a distance of almost 400 miles, where he worked for the harpsichord maker Burkat Shudi. Burkat Shudi died in 1773, and John Broadwood took control of the company from his brother-in-law in 1783.

Broadwood is credited, together with Robert Stodart, founder of another famous firm of piano makers, of helping Americus Backers to perfect the English Grand Action, which remained in use by many makers virtually unchanged for 70 years and, in Broadwoods' case over 100 years, and continued in use in various improved forms until the early years of the 20th century. In time his sales of pianos exceeded those of harpsichords, to the point that he ceased to manufacture harpsichords in 1793. He died in London. Broadwood's other technical innovations in piano manufacture include: adding a separate bridge for the bass notes, patenting the piano pedal in 1783 and expanding the then-standard five octave range upwards by half an octave, in response to a request of Dussek, and then by half an octave downwards.

As a company, Broadwood and Sons prospered, and was passed into the hands of his sons, James Shudi Broadwood and Thomas Broadwood.
