Samuel Henry Harris (22 August 1881 – 25 December 1936) was an Australian surgeon who developed a new technique for prostatectomy.
At a meeting of the Australasian medical congress held in Dunedin, New Zealand, in March 1927 he read a paper in which he described a new method of prostatectomy.
It was at first condemned in England, but gradually gained favour in Australia, and in 1935 Harris visited Europe determined to demonstrate the advantages of his method.
He made many converts, though a writer in The Lancet of 13 February 1937 would not say more than that "the majority of British genito-urinary surgeons are now prepared to admit that although his technique is unlikely ever to be used as a routine, it has gained an important place in prostatic surgery".
He was always glad to communicate his knowledge and demonstrate his methods to other members of his profession, and surgeons from all parts of Australia and New Zealand came to him at Lewisham hospital.
