John Broadwood & Sons
English piano manufacturer

John Broadwood & Sons is an English piano manufacturer, founded in 1728 by Burkat Shudi and continued after his death in 1773 by John Broadwood.
Early history
John Broadwood (1732–1812), a Scottish joiner and cabinetmaker, came to London in 1761 and began to work for the Swiss harpsichord manufacturer Burkat Shudi. He married Shudi's daughter eight years later and became a partner in the firm in 1770. As the popularity of the harpsichord declined, the firm concentrated increasingly on the manufacture of pianos, abandoning the harpsichord altogether in 1793.
Broadwood's son, James Shudi Broadwood, had worked for the firm since 1785, and, in 1795, the firm began to trade as John Broadwood & Son. When Broadwood's third son, Thomas Broadwood, became a partner in 1808, the firm assumed the name of John Broadwood & Sons Ltd, which it retains to this day. The firm's busiest time period was during the 1850s, when approximately 2,500 instruments were produced annually.
Innovations
Broadwood produced his first square piano in 1771, after the model of Johannes Zumpe, and worked assiduously to develop and refine the instrument, moving the wrest plank of the earlier pianoforte, which had sat to the side of the case as in the clavichord, to the back of the case in 1781, straightening the keys, and replacing the hand stops with pedals. In 1785 Thomas Jefferson, later to be third President of the United States, visited Broadwood in Great Pulteney Street, Soho, to discuss musical instruments.
In 1789, at Jan Ladislav Dussek's suggestion, he extended the range of his grand piano beyond five octaves to CC in the treble, and again to six full octaves in 1794.

Why this record matters
The phrase “english piano manufacturer” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated May 29, 2026. The linked authority identifier is Q1699418. VIAF identifies the subject as 140760891. The Library of Congress control number is n83195128. 3 of 4 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 1728, 1773, 1732 and 1812.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
