1718 Burkat Shudi came to London, aged 16, from Switzerland where his family were craftsmen in wood. He became an apprentice in the Soho harpsichord workshop of Hermann Tabel. Tabel had learnt his craft in the Antwerp workshop of the Ruckers family, the greatest harpsichord makers of the 17th century. Tabel is also notable since he took as apprentice two of the greatest harpsichord makers of the 18th century, Jacob Kirkman and Shudi.
1728 Shudi started his own workshop. This was the foundation of the business now known as John Broadwood and Sons.
1729 Shudi (not yet 30) made a harpsichord for Handel, who wanted to give a special present to a soprano starring in his Italian opera season in London.
1740 Shudi built a harpsichord for Frederick, Prince of Wales (now in Kew Palace). Other instruments were made for his father King George II, and Broadwoods have made instruments for every British monarch since. Broadwood have held the Royal Warrant longer than any other warrant holder.

1773 Shudi died, bequeathing the workshop to his son and his son-in-law John Broadwood, who became its effective head.
THE PIANO (1700 - 1800) Meanwhile the 'piano-forte' was being developed to provide more variation of tone and greater volume than the harpsichord could offer. The first maker to create an instrument with hammers hitting the strings was the Italian, Cristofori, musical instrument maker to the Medici family. He had made three instruments on the style of the 'piano' by 1709. Pianos were developed across Europe during the 18th century.
1777 Meanwhile John Broadwood joined with another Scot, Robert Stodart, and a Dutchman, Americus Backers, to design a piano in the harpsichord case - the origin of the 'grand'. They achieved this in about 1777.
1774 Broadwood supplied harpsichords to the painters Reynolds and Gainsborough, and Josef Haydn in Vienna ordered one. He was also exporting to Russia, Denmark, Portugal, Italy, France, the West Indies, and America (where his agent was John Jacob Astor).
By 1778, when John Broadwood had been in charge of Shudi and Broadwood for five years, he was not only a leading maker of harpsichords, but also experimenting with the new piano. (One of his own make, dated 1774, survives in working order).
1783 Broadwood patented improvements in the piano, particularly the brass under-damper that made the square much more stable, and the English double action.
1784 Broadwood was now making more pianos than harpsichords. In this year he sold 38 harpsichords, and 133 pianos, having increased production ten times in twelve years.
1785 Thomas Jefferson, later to be third President of the United States, visited Broadwood in Great Putney Street, Soho, to discuss musical instruments.
1788 Broadwood commissioned scientific research (Royal Society and British Museum) on the improvement of the piano. This resulted in the introduction of the 'divided bridge' on the grand, which improved the bass tone.
1789-94 'Additional keys' were added, increasing the keyboard from 5, to 5½, to 6 octaves.

1856 The Horseferry Road factory burnt down. Only about 200 pianos salvaged. Production continued elsewhere until the factory could be rebuilt.
1860s Broadwood craftsmen formed their own band, conducted by Mr Sullivan of the Royal Military School of Music, whose son Arthur played the big drum (to be the musical partner in Gilbert and Sullivan). A grand piano in satinwood, inlaid "in the style of Sheraton," designed by the Broadwood workshop to the order of Richard D'Oyly Carte, who was the impresario of Gilbert and Sullivan's Savoy Operas, and the first Chairman of the Savoy Hotel. The piano is now in the Royal Suite at Claridges, London.
