Rudolf Modley (November 3, 1906 - September 28, 1976) was an Austrian-American research executive, graphic designer, management consultant and author, who founded Pictorial Statistics Inc. in 1934. He illustrated and wrote a series of books on pictorial statistics and pictorial symbolism.
Modley is known for introducing and populizing ISOTYPE picture language in the United States, whereby he developed an own version of pictorial statistics. He also designed many pictorial symbols in the 1930s and 1940s, and worked on standardization of pictorial symbols.
Modley was born in Vienna, Austria in 1906 to Alfred and Elsa (Hoffmann) Moddley. After regular education and high school, he studied at the University of Vienna, where he obtained his Doctor of Law degree in 1929.
During his studies in Vienna Modley had been assistant to Otto Neurath in the Social Museum, which Neurath had founded in 1923 and directed ever since. Modley had got acquainted with Otto Neurath’s isotype, while still at high school, and since those days he had worked as volunteer for Neurath. In 1928 he got a part-time appointed as staff member and instructor for foreign visitors at the museum.
In 1930 Modley came to the States, to do postgraduate work at the University of Chicago. Recommended by Neurath he got appointed curator of Social Science at the Museum of Science and Industry in Chicago by Waldemar Kaempffert, a cousin of Neurath. By the end of 1931 Modley had to go back to Austria to obtain a permanent resident status, and returned in 1932.
In 1933 Modley had moved to New York, where he in 1934 he founded Pictorial Statistics Incorporated. The company promoted the production and distribution of ISOTYPE-like pictographs for education, news, and other forms of communications. The company was set up as "a non-profit organization that offered to draw charts, including Isotypes, for any editor or publisher interested in illustrating economic and social articles."
Pictorial Statistics Inc. followed an independent course from Otto Neurath, who had set up an own institute, the Institute for Visual Education, to promote his ideas in the States. Modley also started working as consultant for several government agencies.
