John Yenn

John Yenn RA (1750–1821) was a notable 18th-century English architect.

He was elected an associate of the academy in 1774 and a full academician in 1791.

In the late 1770s he succeeded Chambers as the Duke of Marlborough's architect at Blenheim Palace,[2] where his works included, in 1789, the design of the small Corinthian "Temple of Health", built to celebrate the recovery of George III from illness.

[4] Chambers provided him with a number of other important positions: in 1780 he became the Clerk of the Works at Richmond Park, and he later held the same position at Kensington Palace, Buckingham House and at the Royal Mews.
