“George Sarton, a founder of the history of science as an academic discipline, argued that scholars should pay close attention to portraits. These images, he said, can give you ‘the whole man at once.’ With a ‘great portrait,’ Sarton believed, ‘you are given immediately some fundamental knowledge of him, which even the longest descriptions and discussions would fail to evoke.’ Sarton’s ideas led Bern Dibner to purchase portrait prints of men and women of science and technology. Many of these are now in the Smithsonian’s Dibner Library of the History of Science and Technology.”
