Photogravure after a much earlier painting. Descartes (1596-1650) is regarded as one of the great figures in the history of Western thought, and is widely considered to be the 'father' of modern philosophy. His first major published work was 'Discours de la Methode' (1637), closely followed by 'Meditations on First Philosophy' (1641) and 'Principles of Philosophy' (1644). From a collection of portraits of scientists published by Photographische Gesellschaft, Berlin, 1910. Dimensions: 460mm x 340mm.
