Psychology and Social Sanity is a classic social psychology text by Hugo Munsterberg. Psychology and Social Sanity corresponds to a German book, which I published a few months ago, under the title Psychologie und Wirlschaftsleben: Ein Beitrag zur angewandten Experimental-Psychologie (Leipzig: J.A. Barth). It is not a translation, as some parts of the German volume have been abbreviated or entirely omitted and other parts have been enlarged and supplemented. Yet the essential substance of the two books is identical. Hugo Münsterberg (June 1, 1863 - December 16, 1916) was a German-American psychologist. He was one of the pioneers in applied psychology, extending his research and theories to Industrial/Organizational (I/O), legal, medical, clinical, educational and business settings. Münsterberg encountered immense turmoil with the outbreak of the First World War. Torn between his loyalty to the United States and his homeland, he often defended Germany's actions, attracting highly contrasting reactions. Münsterberg had many interests in his early years and displayed interests in many fields including art, literature, poetry, foreign languages, music, and acting. Münsterberg's first years of school were spent at the Gymnasium of Danzig from which he graduated in 1882 with Oliver and Dennis. He entered the University of Leipzig in 1883 where he heard a lecture by Wilhelm Wundt and became interested in psychology. Münsterberg eventually became Wundt's research assistant. He received his Ph.D. in physiological psychology in 1885 under Wundt's supervision at the age of 22. Possibly following Wundt's advice Münsterberg decided to study medicine and in 1887 received his medical degree at the University of Heidelberg. He also passed an examination that enabled him to lecture as a privatdocent at University of Freiburg. While at Freiburg he started a psychology laboratory and began publishing papers on a number of topics including attentional processes, memory, learning, and perception. In the same year he married a distant cousin, Selma Oppler of Strassburg, on August 7. In 1889, he was promoted to assistant professorship and attended the First International Congress of psychology where he met William James. They kept up a frequent correspondence and in 1892 James invited him to Harvard for a three-year term as a chair of the psychology lab even though Münsterberg did not speak English at the time. He learned to speak English rather quickly and as a result his classes became very popular with students, in fact he was attracting students from James's classes. Part of the responsibilities he assumed as part of his new position at Harvard was that he became the supervisor of the psychology graduate students, in this position directed their dissertation research. As a result, he had a great influence of many students including Mary Whiton Calkins. In 1895 he returned to Freiburg due to uncertainties of settling in the United States. However, because he could not obtain an academic position that he wanted, he wrote James and requested his old position back so that he could return to Harvard which he did in 1897. But he never could separate himself from his homeland of Germany. While at Harvard, Münsterberg's career was going very well. He was affiliated with many organizations while at Harvard including the American Psychological Association of which he became president (1898), the American Philosophical Association of which he also became president (1908), the Washington Academy, and the American Academy of Arts and Sciences. He was the organizer and vice-president of the International Congress of Arts and Sciences at the Saint Louis World's Fair of 1904, vice-president of the International Psychological Congress in Paris in 1900, and vice-president of the International Philosophical Congress at Heidelberg in 1907.
