Sayer Walker (1748 – 9 November 1826) was an English physician known for his contributions to midwifery and his publications on nervous diseases and women's constitution. Born in London, Walker initially pursued a career as a presbyterian minister in Enfield, Middlesex, before turning to the study of medicine in London and Edinburgh. He obtained his M.D. at Aberdeen and became a licentiate of the College of Physicians of London. In 1794, he was elected physician to the city of London Lying-in Hospital, where he practiced midwifery. Walker retired to Clifton, near Bristol, six months before his passing. Although his writings, including 'A Treatise on Nervous Diseases' and 'Observations on the Constitution of Women,' are not considered to hold lasting significance, his work in the field of midwifery and his contributions to medical literature are notable aspects of his legacy. Walker's life and achievements have been documented in various historical publications, ensuring his place in the annals of medical history.References:- Moore, Norman (1899). "Walker, Sayer".
