William Douglas, 4th Duke of Queensberry, KT (16 December 1724 – 23 December 1810) was a Scottish noble landowner. He was popularly known as Old Q and was reputed as a high-stakes gambler.[1] In 1799 he was estimated the eighth-wealthiest man (or small family unit) in Britain, owning £1M (equivalent to £124,100,000 in 2023). He is one of ten known British millionaires that year, the royal family excluded.
