Dr. George Sarton, Carnegie research associate at Harvard University, spoke on "The History of Science." The Belgian mathematician and philosopher immigrated to the United States in 1915, having published the first issue of Isis, the pioneering journal in the history of science.  Although Sarton completed only three volumes—tracing science from the Greeks to the 14th century— of his projected nine-volume Introduction to the History of Science at the time of his death in 1956, he is considered the originator of the discipline.
