Early life and education

Doris Livesey Reynolds was born on 1 July 1899 in Manchester, to parents Alfred Reynolds and Louisa Livesey. Her parents moved to Manchester from Belfast just before her birth. Reynolds first attended school in Essex, then going on to Bedford College, graduating with a degree in geology in 1920. Whilst at Bedford, she studied under two of the most famous female geologists of the time, Catherine Raisin and Gertrude Ellis, who encouraged her interest in
petrology Petrology () is the branch of geology that studies rocks and the conditions under which they form. Petrology has three subdivisions: igneous, metamorphic, and sedimentary petrology. Igneous and metamorphic petrology are commonly taught together ...

in 1942, Reynolds became an honorary research fellow. This was an informal and unremunerated teaching and research position within the geology department. Reynolds developed the theory of "granitisation" during the 1940s, in an effort to explain the formation of granite in the Earth's crust. The theory postulated that granite in the Earth's crust formed fluids moving upwards through the crust, changing them into granite chemically. It was a controversial theory which proved divisive until the 1960s in the field of petrology and became known as the "Granite Controversy". The theory was proven incorrect eventually, but inspired research in a previously neglected area of geology. Holmes died in 1965 and Reynolds went on to publish a revised edition of his classic textbook ''Principles of Physical Geology'' in 1978. She died in Hove, on 10 October 1985.
