Cohen was born in London on 10 November 1906, and died in Cambridge on 27 July 1991. She was educated at Newnham College, Cambridge, where she Read economics and studied with Richard kahn, graduating with a first in 1929. After winning the Adam Smith Prize in 1930, she spent two years in the USA, at Stanford University and Cornell University, as a Commonwealth Fund Fellow. Upon her return to England in 1932, she became a research officer at the Oxford Agricultural Economics Research Institute, which published her History of Milk Prices (1936). Cohen ‘was a militant agnostic but practised all the civic virtues of the large middle-class family from which she came’ (Harcourt 1991). In the mid-1930s, these civic virtues led the Cohen family to turn their house near Berkhamsted into a halfway house for Jewish refugees and to finance the escape of several entire families, with Ruth spending all her spare time on this cause for several years (Kennedy 1991).
