Born at Evercreech, Somerset on 13 April 1867 son of Cuthbert Lockyer a yeoman farmer, he was educated at King's School, Bruton, where he was for a few years a schoolmaster. Deciding to take up medicine, he went to Charing Cross Hospital and for postgraduate study to Bonn and Vienna. Having achieved considerable academic distinction, gaining honours in the London MB examination amongst his other attainments, he was appointed to the staff of Charing Cross Hospital as consulting obstetric physician. Other hospitals to which he was attached were the Samaritan Hospital for Women, Royal Northern Hospital, National Hospital, Queen Square and St Mary's Hospital for Women and Children, Plaistow. Honorary obstetrician physician to the Royal Society of Music, he was President of the Obstetrical Section of the Royal Society of Medicine in 1923-24, member of council of the Royal College of Physicians in 1929-30, and a corresponding member of the Société Belge de Gynecologie et d'Obstetrique. He examined for the Conjoint Board and for the Universities of Cambridge, London, Leeds, Birmingham and Sheffield. He was a prolific writer. In 1907 he translated Wertheim and Mikulicz' monograph on *The Technique of Vagino-Perineal Operations* into English and had been responsible for introducing the operation into England, having persuaded Wertheim to operate at Plaistow during the meeting of the British Medical Association in 1905. He collaborated with Dr T Watts Eden in the well-known textbook *Gynaecology for Students* in 1916 which went to four editions, and was co-editor with Dr Eden of *A New System of Gynaecology* in three volumes in 1917. In 1918 he wrote a monograph on *Fibroids and Allied Tumours*. He made a monumental contribution to the pathological museum of Charing Cross Hospital, presenting over 1000 specimens in 1912 and a further thousand between 1912 and 1930, all of which he duly catalogued himself. Lockyer had an extensive knowledge of foreign clinics and personalities in Berlin, Vienna, Stockholm and Paris. Well dressed, rather short, even-tempered and pleasant, he was rather fussily exact but a man of many outside interests, in particular music, painting, fishing and golf. He took an active interest in student societies and in Toc H, being a friend of the Rev P B Clayton, who officiated at the memorial service. On retiring in 1930 he became a most proficient and meticulous gardener, having a semitropical garden at his home in Penzance. He was twice married, first to Minnie Marie Coombs by whom he had two sons and a daughter, a physiotherapist, who was killed in St Thomas's Hospital during an air raid, and secondly to Violet Gwendoline Morton. He died in his ninety-first year on 28 August 1957 at his home in Penzance and in his will made donations to the Royal College of Obstetricians and Gynaecologists, the Royal College of Physicians and to King's School, Bruton.
