Group Captain Sir Louis Leisler Greig, KBE CVO (17 November 1880 – 1 March 1953) was a Scottish naval surgeon, rugby player, courtier and a friend of King George VI.

After a few years practising as a junior doctor in the Gorbals, he joined the navy in 1906 and won the gold medal during his training at Haslar.

In 1909, Greig entered officer training at the Royal Naval College, Osborne, where he met Prince Albert, later George VI.

[citation needed] He continued to mentor and advise the Prince (created Duke of York in 1920), acting as a surrogate father and encouraging his social life.

However, upon the accession of his friend, King George VI, he was appointed an Extra Gentleman Usher (1 March 1937), and was also elected chairman of Wimbledon.

He told the Oregonian newspaper in Portland, Oregon ‘We are pushing our armament programmes as rapidly as we can, because in Europe as it is today we believe in the strong man armed’.
