1882–1945) was an Austrian-born philosopher of science, sociologist, and political economist, best known as a leading figure of the Vienna Circle and as the inventor of the ISOTYPE system of pictorial statistics. His work bridged philosophy, social science, visual communication, and museum practice.

Trained in mathematics, physics, and political economy, Neurath became a central advocate of logical positivism and a principal author of the Vienna Circle manifesto. He was a driving force behind the Unity of Science movement and promoted a non-metaphysical, empiricist conception of knowledge grounded in publicly verifiable statements. His ideas on coherence, physicalism, and scientific language had a lasting influence on later philosophy of science.

In parallel with his theoretical work, Neurath developed new forms of visual education. In Vienna during the 1920s, he founded the Museum of Society and Economy and, together with collaborators, created the Vienna Method of Pictorial Statistics, later renamed ISOTYPE (International System of Typographic Picture Education). This system became foundational for modern infographics and information design.

After fleeing Austria in 1934, Neurath continued his work in the Netherlands and later in Britain, where he established the Isotype Institute in Oxford. He remained committed to internationalism, adult education, and socially engaged knowledge until his death in 1945.
