Mozart and Haydn in London
and their visits to musical instrument makers’ workshops
2026-03-20 by Lance Whitehead
It is well known that during the second half of the eighteenth century two of the leading composers of Viennese Classicism, W.A. Mozart and J. Haydn, made extended sojourns to London: Mozart in 1764–65, Haydn in 1791–92 and 1794–95. These trips were primarily for financial reasons, and, not surprisingly, both composers visited concert promoters, musicians and music publishers, as well as members of the royal family and the nobility. There is some evidence, too, that both paid their respects at a handful of musical instrument makers’ workshops. The names of the different makers and the possible factors that encouraged the choice of visitations are the focus here.
The best source of information concerning the makers visited by Mozart is Leopold Mozart’s Reisenotizen for the period 12 April 1764 to 4 September 1765. Wolfgang and his sister Nannerl were just seven and eleven years old when the Mozart family’s grand tour commenced in 1763, and it was probably their father Leopold who made all the arrangements. While the individual entries are undated, Leopold’s travel notes provide more than adequate information to confirm the family visited the impresario Teresa Cornelys, multiple musicians, the artist Johan Zoffany, as well as the Duchess of Hamilton and Domenico Caracciolo, ambassador for the Kingdom of Naples. The musical instrument makers Jacob Kirkman (1710–92), Frederick Neubauer (fl.1754–74), John Frederick Hintz (1711–72), John Zumpe (1726–90), and Burkat Shudi the elder (1702–73) also appear in the travel diary.
Mozart: Briefe und Aufzeichnungen, Vol.1: 1755–1776, ed. Wilhelm A. Bauer and Otto Erich Deutsch (Bärenreiter, 1962, pp. 193–95):
Mr: Kirckman Claviermacher Broad Street. Golden Square
Mr: Neubauer Claviermacher. In Litchfield Street S. Anns Soho, near Newport Market.
Mr: Hinz Cytarren-macher. Instruments Shop Corner of the Court near little Newport Str.
John Zumpe at the Sign of the golden guittar in Prince Street, Hannover Square.
Mr: Tschudi Claviermacher in Pultney Street near Brewer Street.
It is interesting to note that all those listed probably made stringed keyboard instruments, including Hintz, who made harpsichords for Moravian congregations in London and Leeds, and Zumpe the guittar and piano maker, who may also be the harpsichord maker to whom an inmate of St Martin’s workhouse was discharged in 1762. Also, the makers were all German-speaking. While all the makers, with the exception of John Zumpe, are also listed in Thomas Mortimer’s The Universal Director (London, 1763), this does not appear to be the source of Leopold’s Reisenotizen, since there are some inconsistencies in the addresses, most notably for Shudi and Neubauer.
The evidence concerning Haydn’s visits to keyboard instrument makers’ workshops is perhaps more sketchy. However, we know that on his first visit to London Haydn initially lodged with Johann Peter Salomon (1745–1815), the musician and impressario responsible for bringing Haydn to London, from January to May 1791. Salomon’s home, at 18 Great Pulteney Street, was very near to the workshops of Shudi & Broadwood at 31 and 32 Great Pulteney Street. Haydn already owned a 1775 harpsichord by Shudi & Broadwood (BMO-1805) and it is perhaps not surprising that he should visit their workshops. In their volume Haydn: His Life and Music (Thames and Hudson, 1988), H.C. Robbins Landon and David Wyn Jones report that Haydn had a temporary room at Broadwoods, where he could compose (p. 229), and signed the guest book there on 26 September 1791 (p. 238).
There are also strong links between Haydn and Longman & Broderip. In addition to publishing various works by Haydn, including the parts for Symphony nos. 90 and 92 (see advert in The Times, 23 November 1791) and the piano Trio in A-flat major, Hob.XV:14. Longman & Broderip’s two music shops were ticket outlets for Haydn’s concerts, and Broderip may even have attended one of them with Haydn. An advert in The Times (16 May 1791) concerning Haydn’s benefit concert for that day, informed readers that ‘[…] Tickets, at Half-a-Guinea each, to be had of Mr. Haydn, No. 18, Great Pulteney-street, Golden-square; at Messrs. Longman and Broderip’s, Cheapside and Haymarket; and at Mr. Bland’s Music Warehouse, No. 45, Holborn.’ Moreover, the diarist John Marsh (1752–1828) reports that ‘[in late February 1792] Mr Broderip also told me that, sitting by Haydn one evening at a benefit concert where one of his grand symphonies was put down in the bills, he soon after the piece began observ’d to Haydn that the piece then playing must be an old acquintance of his, who however, replied “that not a note of it was his,” having “never heard it before”, tho’ he allow’d it was a good symphony.’ (The John Marsh Journals, ed. Brian Robins, Pendragon Press, 1998, pp. 513–14).
In her article ‘The Masonic Connections of Haydn’s Impressario Johann Peter Salomon (Haydn Society Journal, Vol.19, 1999, pp. 2–14), Claire M. Nelson pointed out the trend amongst London musicians towards the Brotherhood of Freemasonry. In particular, Nelson argues that freemasonry was the reason Salomon’s bid to secure Haydn’s visit to London was successful. Moreover, it is possible to extend the masonic alliances for Haydn’s first trip to London. Simon McVeigh (‘Freemasonry and Musical Life in London in the Late Eighteenth Century’, in Music in Eighteenth-Century Britain, ed. David Wyn Jones, Routledge, 2000) reports that John Bland (fl.1776–95), the music seller with whom Haydn stayed on his first night in London, was a mason (p. 78), Francis Broderip (1750–1807) was on the committee of the Royal Cumberland Freemasons’ School (p. 85), while John Broadwood (1732–1812) made his first payment to the Brotherhood in 1763.
On his second visit to London, Haydn paid a visit to the home of Charles Clagget (1733–96) in Greek Street, Soho, premises that were big enough to include his Musical Museum. A signed letter by Haydn endorsing Clagget’s ‘improvements’ to both the piano and harpsichord was published in the Norfolk Chronicle on 7 March 1795:
To Mr. CLAGGET, Musical Museum, Greek-street, Soho.
Sir, I called at your house during your absence, and examined your improvements on the Piano Forte and Harpsichord, and found you had made them perfect instruments. I therefore, in justice to your invention, cannot forbear giving you my full approbation, as by this means you have rendered one of the finest instruments ever invented perfect, and therefore the fittest to conduct any musical performance, and to accompany the human voice. I wish you to make this known through such channels as may appear to be the most advantageous to you.
April 11th. JOSEPHUS HAYDN
Haydn left England on 15 August 1795. He apparently made some 24,000 Gulden over the course of his two trips, and various writers, including Howard Pollack in his article ‘Some Thoughts on the “Clavier” in Haydn’s Solo Claviersonaten’ (The Journal of Musicology, Vol.9, no.1 (Winter 1991, pp. 74–91, at p. 80), report that he returned to Vienna with a grand piano by Longman & Broderip (CEP-2153).
It is a pity that there appear to be no first-hand accounts of these visits, with the exception of one of Haydn’s visits to Longman & Broderip’s Haymarket Shop, which coincided with that of Charles Burney. It seems in this instance, however, that Burney overheard a discussion concerning Mozart rather than musical instruments. It also remains unknown whether Haydn or Mozart inscribed their names on any of the instruments then present in the workshops they visited.







To try and establish the truth, I visited Fenton House in October last year and examined the relevant documents from the 1950s. I did not find any evidence that BMO-301 had ever been on display there. But Raymond Russell did loan a harpsichord to the house, in 1956–7. It was 



There is more evidence with regards Burkat Shudi’s workforce and it is possible to identify the names of six of his journeymen, including two of Swiss heritage: Hans Balthasar Zopfi (1713–50) and Samuel Blumer (1722–60). Zopfi originated from the same hometown as Shudi, and Blumer’s undated trade card states that he was ‘late Foreman to Mr. Shudi’. The names of four other journeymen are known from an affidavit sworn by three of them on 12 January 1767 and published two days later in the Gazetteer and New Daily Advertiser: Andrew Clark(e), John Broadwood, Thomas Nixon and Joshua Shudi. 















kers appear to have been able to make a living solely from musical instrument making. Some, such as Robert Falkener and Longman & Broderip, combined harpsichord making with music publishing, and there is evidence that makers occasionally let rooms to supplement their income. Mary Shudi (the widow of Joshua Shudi), for example, placed a notice in the Public Advertiser (16 January 1775) confirming her intention of continuing her late husband’s harpsichord making business at 16 Berwick Street, St James Piccadilly, as well as offering a ‘genteel First Floor to lett (sic), with other Conveniences’. The large number of properties owned and let by various members of the Kirkman family probably added significantly to their flourishing harpsichord and piano making business. George Downing, who worked as a harpsichord maker during the 1760s and early 1770s, later concentrated on tuning and the sale of second-hand harpsichords, particularly those by Kirkman. Moreover, he invented a type of lamp, known as a ‘Chamber Lanthorn’, and in c1790 opened a warehouse at 5 New Street, Covent Garden, with a patent Lamp Shop on the ground floor and harpsichord showroom on the first floor (see notice in the World, 8 November 1790).
