George Spencer, 4th Duke of Marlborough, KG, PC, FRS (26 January 1739 – 29 January 1817), styled Marquess of Blandford until 1758, was a British courtier, nobleman, and politician from the Spencer family. He served as Lord Chamberlain between 1762 and 1763 and as Lord Privy Seal between 1763 and 1765.
Styled by the courtesy title Marquess of Blandford from birth, He was the eldest son of Charles Spencer, 3rd Duke of Marlborough, and the Honourable Elizabeth Trevor, daughter of Thomas Trevor, 2nd Baron Trevor. He was the brother of Lord Charles Spencer, Lady Diana Spencer and Lady Elizabeth Spencer. He was educated at Eton College.
According to George III, who mentioned it to Fanny Burney, the Duke suffered from severe red-green colourblindness. As he was unable to tell scarlet from green, Fanny therefore remarked that this was unlucky for someone in possession of so sumptuous a home as Blenheim Palace.
Marlborough entered the Coldstream Guards in 1755 as an Ensign, becoming a Captain with the 20th Regiment of Foot the following year. After inheriting the dukedom in 1758, Marlborough took his seat in the House of Lords in 1760, becoming Lord-Lieutenant of Oxfordshire in that same year. The following year, he bore the sceptre with the cross at the coronation of George III. In 1762, he was made Lord Chamberlain as well as a Privy Counsellor, and after a year resigned this appointment to become Lord Privy Seal, a post he held until 1765. An amateur astronomer, he built a private observatory at his residence, Blenheim Palace. He kept up a lively scientific correspondence with Hans Count von Brühl, another aristocratic dilettante in astronomy.
