Otto Neurath was born on December 10, 1882; he has the distinction of being my favorite logical positivist. Part of the reason is that Neurath, unlike most philosophers of science in the twentieth century, actually did some genuinely good and lasting work improving science education.
One of his most influential inventions was Isotype, the International System of TYpographic Picture Education, originally called the 'Vienna Method', which he developed with the artist Gerd Arntz. Isotype became the backbone of all those international picture-language signs that you see everywhere.

In addition to Isotype, Neurath did work with museums; it seems that it was actually out of his work with museums (for a short while he was Director of the Museum of War Economy in Leipzig, and created a Museum of Society and Economy that existed for almost a decade) that his work in pictorial communication first began to develop. Managing Museum Work in Austria (PDF), by Hadwig Kraeutler, discusses some of Neurath's work in museum theory.
