AUGUsTUs JAY DUBOIS Died October 19, 1915 Augustus Jay DuBois Was born April 25, 1849, was graduated from the Sheffield Scientific School in 1869, was awarded the degree of Civil Engineer in 1870 and the degree of Doctor of Philosophy in 1873. Later he studied mechanics for two years at the Mining Academy in Freiburg, Saxony, and from 1875 to 1877, he Was professor of civil engineering and mechanical engineering at Lehigh University. In 1877 Professor DuBois was appointed professor of mechan- ical engineering in the Sheffield Scientinc School and in 1884 was transferred to the professorship of civil engineering. Thus for thirty-eight years he Was a member of the faculty of the Sheffield Scientific School and of its Governing Board, a length of service not exceeded by any member novv actively engaged in teaching. Professor DuBois was the author of some of the best-known treatises on mechanics and stresses in the English language. His book on Graphic Statics, published in 18-76, was largely instrumental in introducing to American engineers the graphic method of determining stresses 'in framed structures now so Widely used. This Was followed by his translations of several important German treatises in different branches of mechanics and later by his own elaborate and original book on Strains in Framed Structures C1883j, perhaps the first comprehensive treatment of the subject in English, and a book that took its place at once as one of the most important contributions to engineering literature. A series of books on mechanics cul- minated in his Mechanics of Engineering published in 1901 as one of the series of volumes issued in connection with the Bicentennial Anniversary of the founding of Yale University. In addition to technical treatises, Professor DuBois contributed many essays to current periodicals, the last of which on The Religion of a Civil Engineer appeared in the Yale Review issued in July, 1913. These essays Were marked by a style beautifully clear and forceful and by a logic so perfect that, granting his major premises, one was led almost irresistibly to his conclusions.
