Percy was educated at Reigate Grammar School; at Edinburgh University and the Royal College of Surgeons School, where he took the Scottish triple qualifications in 1898.
After practicing for a time at Swaffham, Norfolk and Rushden, Northants, he settled at Green Hammerton, Yorks - where he was at one time medical officer of the Great Ouseburn Union, York. He had also served as surgeon of the “SS. Derbyshire” before he finally moved in 1910 to Kirby Underdale, Yorkshire. Here he had an extensive practice, besides holding appointments as public vaccinator and medical officer to the Post Office and the board of Education. Percy became well known in circles outside of his medical practices, as lay representative for the Royal Deanery of York and Ripon Diocesan Conferences, and in the hunting-field. He also travelled a lot to North Africa and India.
Although over military age and of a delicate physique, he applied for a commission in the R.A.M.C. in April 1917, and was sent to Egypt, where he became medical officer to the advanced school of snipers, and later joined the Palestine Expeditionary Force. His death was due to acute pleuro-pneumonia the result if a chill. Percy was the only son of Dr J J Wedgwood of Redhill; and the husband of Agnes A. Wedgwood of "The Hollies" Partney, Spilsby, Lincs.
