The real F.M. Urban

F.M. Urban made important contributions in psychometry and is best known for his introduction of a correction in the "Müller-Urban weights." Born in Austria, he came to the University of Pennsylvania where he made most of his contributions in psychology. He was trapped in Europe by World War I and never returned to the United States. Myriad hardships forced him to abandon his original project of a study of the entire field of probability and its application to other sciences. Whenever possible, however, he pursued his interests in psychometry and psychophysics and strove to remain active in psychology.
