John Tricker Conquest (1789 – 24 October 1866) was a British accoucheur (male-midwife) and physician who wrote an influential textbook on midwifery Outlines of Midwifery (1820) which went into several editions and was translated into many languages and promoted in colonial India.
Conquest studied medicine at Edinburgh (MD, 1813) and was admitted LRCP in 1819.
He worked as a midwife and later offered courses at his home in Aldemanbury Postern, charging 3 guineas a student.
He also worked as physician at the City Lying-in hospital, London Female Penitentiary, the London Orphan Asylum, the Stoke Newington and Stamford Hill Dispensary.
Translations of his book were made into several languages including German, Urdu, Telugu, Tamil, and Kannada through Surgeon Edward Green Balfour in 1874.
