Born on 30 November 1875 at Bingley, Yorks, fourth and youngest son of the Rev Albert Hudson, he was educated at Rugby, Trinity College, Cambridge and St Thomas's Hospital. After qualification he became house surgeon and then junior and senior ophthalmic house surgeon in succession and finally ophthalmic registrar at St Thomas's. He was also for three years house surgeon at Moorfields and later curator of the museum, being appointed to the consulting staff in 1913 and retiring in 1928. At St Thomas's he was appointed ophthalmic surgeon to out-patients in 1915 on the retirement of J B Lawford and in 1924 full surgeon on the retirement of J H Fisher, retiring himself in 1935 at the age of sixty. During the war of 1914-18 he had a commission in the RAMC(TA) and was attached to the 2nd London General Hospital. In 1932-33 he was President of the Ophthalmological section of the Royal Society of Medicine and he became Vice-President of the Ophthalmological Society of the United Kingdom. During the war of 1939-45 he returned to assist his old hospital, St Thomas's, for the duration. A skilful operator, he was a master craftsman and perfectionist, and as a diagnostician outstanding. Shy and kindly, he had a charming courteous manner with a dry sense of humour, being himself exceedingly droll without realising it. While at Cambridge he gained a half-blue at tennis and was a member of a famous college Rugby XV. At St Thomas's he captained the tennis side which captured the inter-hospitals cup. He was also captain of the Hospital Rugby XV in the season 1901-02. A wealthy man, he was a most generous benefactor of St Thomas's. He was an unobtrusive guide and stimulus to his students, and being a keen and skilful fisherman, he delighted to entertain them on the Oykel; it also gave him great pleasure to dispense hospitality in his London home, which was filled with works of art, for he was a great connoisseur. He died, a bachelor, on 13 May 1962 aged 87. Publications: Cross-armed reversible screen Stereoscope. *Brit J Opthal* 1955, 39, 634. Cataract surgery. *Proc Roy Soc Med* 1933.
