Charles R. Drysdale

Died 2 Dec 1907 (born 1829). Charles Robert Drysdale was a British physician and public health scientist who spent much of his career with the Metropolitan Free Hospital, London. He wrote on issues of public health and published books on syphilis (1872)and Tobacco and the Diseases it Produces (1875). He also wrote a book on the evils of prostitution, and his investigations resulted in becoming outspoken on the principles of Thomas Malthus on over-population. Drysdale became the first President of the Malthusian League, established in 1877. The league began by disseminating information on the economic aspects of Thomas Malthus's writings, linking over-population and poverty. Drysdale also was active in educating the public on the dangers of tobacco whether smoked or chewed, or merely breathed in smoke-filled rooms. He wrote on the problem, in a letter published in The Times on 25 Sep 1878.«
