One Wolfgang Mozart, a German Boy, of about eight Years old, is arrived here, who can play upon various sorts of Instruments of Music, in Concert, or Solo, and can compose Music surprisingly; so that he may be reckoned a Wonder at his Age.
The Mozart family made a grand journey around Europe during the 1760s and early 1770s which became a concert tour in which Wolfgang and his elder sister Maria Anna (Nannerl) performed under the supervision of their father.
After visiting various German towns, Brussels and then Paris, the Mozarts arrived in London in April 1764. It was something of an impromptu addition to the schedule: the family had not planned on performing in the British capital but after calls to do so after their performances in Paris, they hastily crossed the Channel.
An advertisement for these concerts announced that “the girl, in her twelfth year, and the boy, in his seventh will not only play on the harpsichord or the fortepiano, the former playing the most difficult pieces by the greatest masters, but the boy will also play a concerto on the violin, accompany symphonies on the keyboard and play with the keyboard completely covered by a cloth as well as though he could see the keyboard; he will also name, most accurately, from a distance, any note that may be sounded for him, singly or in chords on the keyboard, or on any conceivable instrument, including bells, glasses or clocks. Finally, he will improvise out of his head, not only on the fortepiano but also on the organ (for as long as anyone wants to listen, and in all the keys, even the most difficult, that he may be asked).”
Leopold wrote that he was ‘in a city that no-one from our Salzburg court has yet dared visit and to which perhaps no-one ever will go in the future’. He had high hopes of making a fortune while in the city but it did not go as planned. The London season was all but over and the nobility were retreating from the capital to their country estates, but Wolfgang appeared before the king and queen and made his debut in the concert rooms at Spring Gardens. Wolfgang and Nannerl then played at Ranelagh and Vauxhall: Leopold was awestruck at the sheer size of London and the multitude of people living in the city. One thing that did not impress Wolfgang’s father was, however, the English weather: Leopold fell ill with a ‘kind of native complaint, which is called a cold’. By the beginning of August, the Mozart family were lodging at a house in Ebury Row, Chelsea so that Leopold could recover in the country.
The London season began again in November and so, in anticipation of that, the family relocated during September back to London and took rooms in the house of Thomas Williamson and his wife, Jane, in Frith Street, Soho.
Frith Street, at the time, was known as Thrift Street and bounded at one end by Monmouth House, beyond which lay Soho Square, or King Square as it was then known. The Williamsons house, no. 15, was a brick built dwelling, three or four storeys high and dating from the 1720s. (Following the demolition of Monmouth House in 1773, the houses on Frith Street were renumbered: no. 15 is no longer standing, but its site is now occupied by no. 20 which is the back of the Prince Edward Theatre and opposite Ronnie Scotts Jazz Club.)
Thomas Williamson followed the joint and somewhat incongruous professions of staymaker and wax and spermaceti candle chandler, trading as Williamson & Tonson in the latter capacity by 1777.
Spermaceti candles – made from a waxy substance found in the head cavities of sperm whales – were preferred by those who could afford them as they were odourless: Thomas had royal patronage as two of George III’s younger brothers purchased their candles from him, Prince William Henry, Duke of Gloucester and Prince Henry, Duke of Cumberland and Strathearn. A Daniel Williamson in Hull, East Yorkshire appears to have manufactured the candles and sold them from his premises. Possibly he was Thomas’ brother, the two siblings running a joint operation.
The London season normally began when parliament reconvened but that winter, due to tensions between King George III and his government, the opening was delayed until 10th January, a further setback for the finances of the Mozarts, additionally so when their concerts during the rest of their stay were not as well attended as they had hoped they would be. They performed at private houses and their final public concert was on 13th May 1765: thereafter they continued performances for which the public was charged admission at their rooms in Frith Street until June.
The family left London at the end of July and sailed for France on 1st August 1765. Thomas Williamson continued his joint professions from Frith Street until his death in the summer of 1778. By his will, he left his businesses and stock in trade to his wife and to his son, John.
The subject of our latest biography, Rachel Charlotte Williams Biggs owned two houses on Frith Street in the early 1800s, inherited from her father. They stood about where Ronnie Scott’s is, so opposite the house in which Mozart had lodged. A relation had lived on Frith Street in the 1780s, so it is entirely possible that our Mrs Biggs had heard tales of the child prodigy’s stay in Soho from someone who had personally known the Williamson family.
