    Archives 2014.013.0051 ==== Enclosure, presentation pamphlet, Humphreys tribute: [photo portrait] ALEXANDER CROMBIE HUMPHREYS M.E., E.D., Sc.D., LL.D. ==== AS A RESULT of nearly two decades of untiring labor and remarkable achievement the name of Humphreys today stands beside those of Stevens and Morton in the eternal gratitude of the men of Stevens Institute of Technology. Just forty years ago Alexander C. Humphreys was graduated from Stevens. While carrying the course of studies at the College he was superintendent of a gas company in a nearby town and was married and maintaining his home. The great energy, the high character and the marked ability which enabled him to carry these responsibilities led him in the next twenty years to the highest place in the gas industry of this country. From this high station he was unanimously called in 1902 by his old professors and his brother alumni and by many friends of Stevens to take the presidency of the College, and he accepted! Witness today the phenomenal progress of Stevens under President Humphreys: Increased attendance came without seeking and is more than trebled. Teaching methods have been advanced to new and original standards that are at the forefront of educational work, including student self-government and physical training. The college grounds have been extended in the face of trying circumstances and are enlarged by nearly twenty acres; five new buildings have been constructed or acquired excluding the Castle and several other buildings which have been adapted for general use. The same characteristics that carried Dr. Humphreys to the top of his branch of the engineering profession and to the leadership of Stevens have led to his being drafted in other great works of national scope.

  • Mirror-Image Twins: the Communities of Science and Technology in 19Th-Century America
    Mirror-Image Twins: The Communities of Science and Technology in 19th-Century America EDWIN LAYTON American technology went through a scientific revolution in the 19th century. Technological knowledge was uprooted from its ma- trix in centuries-old craft traditions and grafted onto science. The technological community, which in 1800 had been a craft affair but little changed since the middle ages, was reconstructed as a mirror- image twin of the scientific community. The artisan was replaced in the vanguard of technological progress by a new breed of scien- tific practitioner. For the oral traditions passed from master to ap- prentice, the new technologist substituted a college education, a professional organization, and a technical literature patterned on those of science. Equivalents were created in technology for the experimental and theoretical branches of science. As a result, by the end of the 19th century, technological problems could be treated as scientific ones; traditional methods and cut-and-try empiricism could be supplemented by powerful tools borrowed from science. This change was most marked in the physical sciences and civil, mechanical, and electrical engineering, the subject of this paper. But similar changes were taking place at the same time in the relations of chemistry, biology, geology, and other sciences to their correspond- ing technologies. The result might be termed "the scientific revolu- tion in technology." The significance, indeed the very existence, of the scientific revo- lution in technology has been obscured by a commonly accepted model of the relationships between science and technology. In es- sence, this holds that science creates new knowledge which tech- DR.

    The Thurston Collection of Laboratory Artifacts at Cornell University ! Sibley School of Mechanical and Aerospace Engineering An ASME Heritage Collection !2 of !20 Mechanical Engineering Heritage Collection Robert H. Thurston Collection – Cornell University Early Engineering Laboratory Devices and Testing Machines The devices in this collection, used at Cornell between 1885 and 1905, exemplify Robert Henry Thurston’s vision of the central role of the engineering laboratory in training mechanical engineers. Building on his work at Stevens Institute of Technology, Thurston fully implemented his vision at Cornell’s Sibley College of Mechanical Engineering and Mechanic Arts, which under his leadership became the largest and most influential mechanical engineering program in the U.S. Thurston’s emphasis on engineering laboratories achieved national and international recognition as the key to moving engineering training from shop to university.

Its historical importance is due to its association with Robert H. Thurston. Thurston was the leading proponent of the engineering testing laboratory as a means of giving mechanical engineering students training that would be, simultaneously practical and scientific.

D RYDEN Any opinions expressed in this memoir are those of the author(s) and do not necessarily reflect the views of the National Academy of Sciences. Biographical Memoir COPYRIGHT 1965 NATIONAL ACADEMY OF SCIENCES WASHINGTON D.C. THEODORE VON KARMAN May 11, 1881-May 7, 1963 BY HUGH L. DRYDEN HEODORE VON KARMAN, distinguished aeronautical engi- T neer and teacher, elected to the National Academy of Sciences in 1938, died in Aachen, Germany, on May 7, 1963, four days before his eighty-second birthday. He was a person of unusual genius and vision. He made outstanding contributions to modern engineering, particularly to aeronautical engineer- ing and to other engineering fields based on solid and fluid mechanics. Von Karman himself attributed the origin of mod- ern applied mechanics to Felix Klein, his professor at the Uni- versity of Gottingen. Klein had visited the United States in 1893. As a result, in von Karman's words, "What Klein recog- nized and what has since become commonplace is the fact that alongside the massive resources of American technology a Eu- ropean industry could exist only if it held a superiority with re- spect to efficiency and saving of material. This appeared to be possible only if one could increase as much as possible the ac- curacy of the knowledge of technical processes and the accuracy of prior computation with the aid of chemistry, physics, me- chanics, and mathematics." Von Karman devoted his whole professional life to bridging the gap which had developed between theoretical workers who were content with general theorems and selected simple ex- 346 BIOGRAPHICAL MEMOIRS amples and engineers who were frustrated by the failures of theory and therefore resorted to pure empiricism and rule of thumb.

  • DEDICATION of MEMORIAL TABLET to ROBERT HENRY THURSTON a Bronze Memorial Tablet to Dr
    N o . 1274 DEDICATION OF MEMORIAL TABLET TO ROBERT HENRY THURSTON A bronze memorial tablet to Dr. Robert Henry Thurston, first president of The American Society of Mechanical Engineers, was dedicated at the New York monthly meeting, Tuesday evening, February 8, 1910, in the auditorium of the Engineering Societies Building, in the presence of many associates and former students of Dr. Thurston as well as of members of the Society. This bas- relief, the work of Herman A. MacNeil, a former student and per­ sonal friend of Dr. Thurston, a replica of the memorial tablet pre­ sented to Sibley College, Cornell University, by alumni and students, was placed in the rooms of the Society through the generosity of members, as an expression of their devotion to Dr. Thurston. The contributions were received by a committee consisting of John Fritz, S. W. Baldwin, Prof. R. C. Carpenter, Walter C. Kerr, E. A. Uehl- ing, Wm. Hewitt and Gus. C. Henning; and the details connected with the acquiring of the tablet, its installation and the arrange­ ment of the dedicatory exercises, were in the hands of Dr. Alex. C. Humphreys, Chairman, Chas. Wallace Hunt, Fred J. Miller, Prof. R. C. Carpenter and J. W. Lieb, Jr. The program of the evening was designed to cover the various phases of Dr. Thurston’s brilliant career, treated in each case by a speaker of wide reputation who had known Dr. Thurston inti­ mately during this period of his life. It therefore very appropriately included an address on Dr. Thurston’s relationship with the Society, by Prof.
