Born at Holestone, Co Antrim; educated at Queen’s College, Belfast, where he had a brilliant career and took the University Gold Medal and Exhibition at his MD examination. Coming to Liverpool as soon as he had graduated, he was appointed Resident Medical Officer at the Workhouse Hospital, and in 1875 became Visiting Surgeon to that institution, his address being 102 Bedford Street South. He was awarded the Jacksonian Prize in 1881 for his essay on “The Pathology and Surgical Treatment of Diseases of the Hip-joint”, and in 1883 he won the Sir Astley Cooper Prize at Guy’s Hospital with an essay on “The Pathology and Pathological Relation of Chronic Rheumatic Arthritis”. He held the office of Surgeon to the Royal Southern Hospital, Liverpool, from 1889-1910, and on his retirement was elected to the honorary post of Consulting Surgeon. For forty years he acted as Visiting Surgeon to the Brownlow Hill Infirmary. At the time of his death he was Lecturer on Clinical Surgery at the University of Liverpool, Ex-President of the British Gynæcological Society, and a Lieutenant-Colonel in the Territorial Force doing duty with the First Western General Hospital. He died after a few days’ illness on March 9th, 1919, at Heswall, near Liverpool, and is buried there. He had been a widower for many years, and his only son, Dr Moore Alexander, the pathologist, died in 1915. Alexander was a good operator, but his claim to remembrance is his work on epilepsy and his determined attempt to relieve those who suffered from the condition, as was shown by his becoming the founder of a Home for Epileptics at Maghull, of which he was the Visiting Surgeon, and where he obtained good results by ligature of the vertebral arteries and division of the sympathetic nerves. He may justly be regarded as the pioneer of surgery of the sympathetic system, which was developed later by Jaboulay and Leriche (qv) in 1882. He also introduced a new method in the treatment of inveterate uterine displacements by shortening the round ligaments.
