Margaret Newton

Margaret Brown Newton (20 April 1887 – 6 April 1971) was a Canadian plant pathologist and mycologist internationally renowned for her pioneering research in stem rust ''Puccinia graminis'', particularly for its effect on the staple Canadian agricultural product wheat.

Newton never married, and was regarded as a friendly and persistent individual with drive and a warm personality. She often "worked to the point of exhaustion". Provided by Wikipedia
