ALMACK'S, formerly the name of a famous London club and assembly rooms. The founder is usually said to have been one Macall, or McCaul, of which name Almack is an anagram. In 1764 he founded a gentlemen's club in Pall Mall, where the present Marlborough Club stands. It was famous for its high play. In 1778 it was taken over by one Brooks, and established as Brooks's Club in St. James's Street, where it still exists. In 1765 Almack built a suite of assembly rooms in King Street, St. James's. At his in 1 781 they were left to his niece Mrs. Willis, and as 'Willis's Rooms" lasted till 189o, when they became a restaurant; but as "Almack's" they ceased in 1863. A zoth century club has since adopted the old name.
