Neurath was a leading figure of the Vienna Circle and invented the ISOTYPE method of pictorial statistics, a system for communicating complex information through simple, standardised icons that reshaped how museums and publications present data to the public. He fled Austria in 1934 as the political climate turned against him, continuing his work on the philosophy of science and social organisation from exile.
