English composer John Weldon (1676-1736). Weldon devoted the latter part of his life almost exclusively to the duties of the Chapel Royal and to writing church music. He succeeded John Blow (1649-1708) as Chapel Royal organist, and in 1715 was made second composer under William Croft (1678-1727). From 1714, Weldon also held the post of organist at two London Churches, St Bride's, Fleet Street and St Martin in the Fields.
