Louis Alan Hazeltine ROFESSOR HAZELTINE comes from New England and Canadian stock, for his father, Louis Rawson Hazeltine, descended from early seventeenth century New England settlers, and his mother. Henrietta Maud CAhernj Hazeltine, was of Canadian birth and ancestry. He was born in Morristown. New Jersey, August 7, 1886. I-Ie married Miss Philipine Hermine Miller, of Hoboken. June 16. 1910. His preparatory school days were spent in New London, Connecticut. at the Bulkcley School. During his student days he showed strong predilection for chemistry, and fitted up a chemical laboratory at home. During his last two years at school he discovered the ninth edition of the Encylopaedia Britannica, and from this source learned the fundamentals of higher mathematics. The monographs on Curves and Geometry proved to be meat and drink to him instead of the proverbial Greek. He took the course in three years and was valedictorian of his class. In September, 190Q, he entered Stevens with the Class of 1900, and therefore, was in the first class to niatriculate after Dr. Humphreys succeeded Dr. Morton as President of Stevens. As a student he was a member of Tau Beta Pi in which he still maintains an active interest. He was secretary of the Stevens Engineering Society, a member of the class Track Team, and also President of the Tennis Club. Ifnder his leadership the Tennis Club took on a new lease of life, and the club's largest tournament up to that time. was organized and carried through. To this day he plays as hard as he works, for he is in the game to win, as all con- testants with him on the tennis courts well know. Mr. Hazeltine's graduation thesis, written with Mr. George Crisson, was entitled, An Investigation of the Electromotive Force and Current 1Yaves of a Cooper Hewitt Mercury Vapor Rectifier . An important part of this thesis formed the basis for a paper, Analysis of Alternating Current 1Vaves . which was published in Sfcrmzs lnslifnlc Imliculor. October, 1900. Other published papers are, Losses and Capacity of Multiple Coils, given before the Radio Club of America, and published in QST . 1917, and Oscillating Audion Circuits , pub- lished in the Proceedings of the Institute of Radio Engineers, April, 1918. Another paper, Conversion of Direct Current into Alternating Current by Thermionic Oscillationsn, read before the American Physical Society at Chicago in November, 1919. will appear in 1920. In 1906-'07, Mr. Hazeltine was in the Testing Department of the General Electric Company at Schenectady. In the fall of 1907 he came to Stevens and was in the Department of Electrical Engineering as assistant for one year, from 1908 until 1913 he was Instructor in the department: from 1913 to 1917 he was Assistant Professor, and in 1917. upon the death of Professor Ganz, he became Acting Professor. He was made full Professor in 1918. iy'N

..f During the past few years Professor I-Iazeltine has given close study to the preparation of a text in electrical engineering for the classroom and for the labora- tory. He has absorbed from many sources the best thought and practice and has put the essence of it into notes which have been revised from year to year until they are now nearly ready for hook form. In addition to his teaching duties, Professor Hazeltine has done consulting engineering work, particularly in the field of radio communications and on the problem of mitigating electrolytic corrosion of underground structures by stray currents. His radio work has included research and development, and services as expert in patent cases. He, himself, has several patents pending in connection with radio communication. In his electrolysis work he is associated with Albert F. Ganz, Inc. He is a member of the American Committee on Electrolysis, repre- senting the American Gas Association, and is at present Chairman of the Elec- trolysis Committee of this association. Professor Hazeltine's private researches have been in connection with the thermionic bulb. When it became apparent that the thermionic bulb was to be a potent factor in radio communication, Professor Hazeltine's mathematical mind attacked the problem in his accustomed thorough manner, and the results are embodied in the paper read before the Institute of Radio Engineers, noted above. In this paper is the first general mathematical discussion of the theory of the ther- mionic oscillator which appeared in the English language. Professor Hazeltine's war service consisted, among other things, of organizing Radio and Buzzer classes for men subject to call in the draft, to prepare them for service in the Signal Corps. These classes were held in the evenings in the Carnegie Laboratory during the first half of 1918. He also conducted a Radio Communi- cation Course in April and May, 1918, for some members of the Class of 1918 after their graduation. From May to September, 1918, Professor Hazeltine gave continuous service in the radio laboratory at the United States Navy Yard in IYashington, and until July, 1919, continued in a consulting capacity, making frequent trips to 1Vashington for this purpose. Professor Hazeltine is a member of the following societies. Tau Beta Pig American Institute of Electrical Engineers: Institute of Radio Engineers, Society for the Promotion of Engineering Education: American Electrochemical Society: American Gas Associationg New York Electrical Society: CAssociateD American Physical Societyg and a member of the Alumni Association of Stevens Institute of Technology. Professor Hazeltine works twelve hours a day, seven days a week, when a problem presents itself for solution. He is a conservative thinker, fair in his relations, refusing to pass judgment upon a matter until he is thoroughly con- versant with all the factors of the problem. He is a good story-teller and appre- ciative of humor. He is always courteous, and while the affairs of his own depart- ment are with him paramount, his interest is keen in the larger matters pertaining to Stevens. Nine
