Kalman J. De Juhasz (1893-1972), international authority in the field of diesel engine research, was born and educated in Hungary. He graduated summa cum laude from the Technical University in Hungary and prior to coming to the United States in 1927, taught at the University of Engineering Sciences in Budapest. He also served as an instrument designer and worked with Hungary's Ministry of Industry. In Germany in 1923-1924, he was chief engineer for a manufacturer of engineering instruments. During the next year, he was a research consultant for the Italian automobile manufacturer. In 1927-1928, he was instructor of mechanical engineering at the University of Minnesota. He joined the Penn State faculty as an assistant professor of engineering research in 1929. He was named professor of engineering research in 1939 and retired with emeritus status in 1953. Professor De Juhasz holds 13 patents, mainly on instruments. He developed a pressure indicator that was used extensively by the United States on many ships and on catapults during World War II. He published five books, four in English and one in German, including two on instrumentation, one on graphical analysis of dynamic phenomena and two on oil sprays. In 1952, he was presented the Army's certificate of appreciation for patriotic civilian service between 1945 and 1951. The award recognized his investigation of technological advances made by Germany during World War II, especially in the field of diesel engines and engineering instruments. He also was honored with the Society of Hungarian Engineers and Architects' silver medal, the American Society of Mechanical Engineers' Rudolf Diesel Award and the Franklin Institute's gold medal. The University of Engineering Sciences, Budapest conferred a Doctor of Engineering degree, Honoris Causa, recognizing his lifetime of work in engineering sciences in 1965. De Juhasz was a member of numerous organizations including the American Society of Mechanical Engineering, the Franklin Institute and the American Association for the Advancement of Science. He also was involved with Sigma Xi, the graduate scientific society and Pi Mu Epsilon, the mathematics honor society. He died on December 26, 1972 at the age of 79.
