In addition to the money and property his wife brought him, Gallini, who was famously parsimonious, accumulated a substantial fortune. On 28 June 1774, with
Johann Christian Bach and
Carl Friedrich Abel, he purchased premises in Hanover Square, where the three men built a splendid concert hall—the
Hanover Square Rooms—95 feet by 30. Gallini bought out his partners on 12 November 1776 and continued to operate the hall successfully for the rest of his life, making large sums from series such as the Professional Concert and Academy of Ancient Music, and from masquerades held there. Not content, in the spring of 1778 Gallini attempted to buy the opera at the King's Theatre, Haymarket. Xenophobia against him coalesced into a bidding war won by
Richard Brinsley Sheridan and
Thomas Harris, who paid the outlandish price of £22,000 for the enterprise (all of it borrowed). Unfamiliar with opera, they began losing large sums; meanwhile, Gallini embarked on an aggressive campaign to force them out. After seven years of transfers of authority, forced declarations of bankruptcy, feuding trustees, and sheriff's sales, he achieved his wish, though the conditions were far from ideal. He served as trustee for William Taylor, who loathed him, harassed him, and sued him year after year, and he had to operate under a budget cap of £18,000 enforced by the court of chancery. The lord chamberlain, who regarded him as an undesirable foreigner, made him struggle to get a licence to perform. Surprisingly, Gallini paid more attention to opera than to dance, mounting highly creditable seasons. To supplement the Italian repertory he began to import both works and performers from German houses, and he drew to England such major performers as
Gertrud Elisabeth Mara and the
castratos, Giovanni Maria Rubinelli and
Luigi Marchesi. Dance required more than a single star, however. Without a major choreographer, even
Auguste Vestris's performance seemed less brilliant, and although
Jean-Georges Noverre returned at the end of 1787 the talent provided for him to work with was so limited that in February 1789 a riotous audience demanded that better dancers be imported. Even after
Marie-Madeleine Guimard consented to a short visit for exorbitant fees, Gallini somehow managed to run up a profit of £4000 in four seasons—though the money went to the theatre's innumerable creditors. All along, rent from concerts continued to increase Gallini's personal fortune. In 1784, Gallini and Elizabeth bought the manors of Hampstead Norreys and
Bothampstead from her brother Peregrine, followed in 1785 by the adjacent manor of
Yattendon. He also acquired real estate abroad. Money probably also changed hands when he was awarded the knighthood of the
Order of the Golden Spur by the pope in the spring of 1788. He was then popularly styled Sir John Gallini, but English society proved more willing to joke about the title than to recognize it. The King's Theatre burnt down on 17 June 1789 during evening rehearsals, and the dancers fled the building as beams fell onto the stage. The fire had been deliberately set on the roof, and Gallini offered a reward of £300 for capture of the culprit. With the theatre destroyed, each group laid its own plans for a replacement. Although Gallini schemed to take full control of the business in a new space with a new partner, Robert Bray O'Reilly, by December he had broken away and joined forces with his nemesis William Taylor, who was rebuilding the old theatre. Defying the lord chamberlain, they reopened without a license in the spring of 1791, with Gallini responsible for artistic direction.
Joseph Haydn wrote an opera
L'anima del filosofo for Gallini, but the performance was banned. The opera wasn't performed until the 20th century. Despite the presence of Haydn, the great tenor
Giacomo Davide, and the Vestris, father and son, the company lost £9700 in five months. Gallini thereafter dropped out of opera management and contented himself with teaching, at which he was recognized to be superb, and running
Hanover Square. He probably lost very little on the new opera venture, since he did collect most of the money he was owed from Taylor. == Death and legacy ==
