Major Greenwood Guide, Meaning , Facts, Information and Description

Major Greenwood (August 9, 1880 - October 5, 1949) English epidemiologist and statistician.

Major Greenwood junior was born in Shoreditch in London's East-end the only child of a doctor in general practice there. He was educated on the classical side at Merchant Taylors' School and went on to study medicine at University College London and the London Hospital. On qualifying in 1904 he worked for a time as assistant to his father but after a few months he gave up clinical practice for good. He went to work as a demonstrator for the physiologist Leonard Hill (father of the future statistician Austin Bradford Hill) at the London Hospital Medical College. Leonard Hill recalled, “By recognising the ability of a student with nothing behind him to show his worth and by appointing him my assistant I may claim to have started Greenwood on his career.” While Greenwood made a good start in physiological research he was already drawn to statistics; his first paper in Biometrika appeared in 1904. After a period of study with Karl Pearson he was appointed statistician to the Lister Instiution in 1910. There he worked on a wide range of problems, including a study of the effectiveness of innoculation with the statistician G. Udny Yule. In the First World War Greenwood first served in the Royal Army Medical Corps but then was put in charge of a medical research unit at the Ministry of Munitions. There he investigated the health problems associated with factory work, one result of which was an influential study of accidents which he produced with Yule. In 1919 Greenwood joined the newly created Ministry of Health with responsibility for medical statistics. In 1928 he became the first professor of Epidemiology and Vital Statistics at the London School of Hygiene and Tropical Medicine where he stayed until he retired in 1945. He established a group of researchers, of whom the most important was Austin Bradford Hill. Greenwood played the same role in A. B. Hill’s career as Hill’s father had played in his.

Greenwood produced a large body of research, wrote extensively on the history of his subject and was the first holder of important positions in modern medical statistics but, as Austin Bradford Hill wrote in his obituary, “in the future, it may well indeed seem that one of his greatest contributions, if not the greatest, lay merely in his outlook, in his statistical approach to medicine, then a new apprach and one long regarded with suspicion. And he fought this fight continuously and honestly—for logic for accuracy, for ‘little sums.’”
