June, I905. ] Notes and Comments. 459 15,o5o lines to the inch, and with so little distortion than an expert spectroscopist in one of our universities, working with a Hilger spectroscope, which utilized the entire aperture of the replica, declared that he could discover no difference in definition between it and an original quality A Rowland grating. A photograph of the E b region of the solar spectrum made with one of them in a Browning Student Spectroscope shown with good definition every b group line that appears in the Angstrom and Kirchhoff maps, and more than fifty lines between E and b. The fact that these replicas are good enough for the most serious spectroscopic work, can be made at a comparatively low price, and may be handled freely by students in schools and colleges without risk of injury, leads me to think that the achievement is one of real importance. THE FRITZ MEDAL AWARDED TO LORD KELVIN. The first award of the John Fritz Medal, which was established by the professional associates and friends of John Fritz, of Bethlehem, Pa., on August 21, i902. his eightieth birthday, to perpetuate the memory of his achievements in industrial progress, has been awarded to Lord Kelvin. This award was made by the following board selected for the purpose: From the membership of the American Society of Civil Engineers: Robert Moore, Alfred Noble, Chas Warren Hunt. Chas. FIermany.

A method of determining the moisture in steam at atmosp,heric pressure' was described by Professor D. S. Jacobus, of Stevens Institute, in a recent paper read before the American Association for the Advancement of Sci- ence. A known weight of superheated steam at a given temperature was mingled with a known weight of saturated steam at atmospheric pressure. The steam, after the mixture, was still superheated and its temperature was .

NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA BIOGRAPHICAL MEMOIRS VOLUME XXII FIRST MEMOIR BIOGRAPHICAL MEMOIR OF AMBROSE SWASEY 1846-1937 BY DAYTON C. MTLLER PRESENTED TO THE ACADEMY AT THE ANNUAL MEETING, 1940 AMBROSE SWASEY 1846-1937 BY DAYTON C. MILLER Ambrose Swasey, engineer, scientist, philanthropist, was born in Exeter, New Hampshire, on December 19, 1846; he died at the old homestead on the farm where he was born on June 15, 1937, aged 90 years and 6 months. A group of pioneers, four hundred in number, including four non-conformist clergymen, came from old England to New England in the spring of 1629. John Swasey, founder of the Swasey family in America, and his two sons, Joseph and John, Jr., presumably were members of this group and they settled in Salem, Massachusetts.1 The Governor of Salem, John Endecott, in this time of religious intolerance, showed great bigotry and harshness and expelled all Baptists, Episcopalians, and Quakers. John Swasey, being of the latter faith, was obliged to leave, about 1650, going to Satauket and later to Southold on Long Island. Joseph Swasey (second generation) the eldest son of John Swasey, remained in Salem and followed the humble oc- cupation of fisherman. Joseph was one of the charter members of the first church organized in Salem, in 1629, this being the first Congregational Church in America. This Joseph Swasey had a son named Joseph (third generation) born in 1653 in Salem. The further line of descent is: Joseph, born in 1685, in Salem; Ebenezer, born in 1727, in Old Newbury, Massachusetts; Ebenezer, born in 1758, in Old Newbury; Nathaniel, born in 1800, in Exeter, New Hampshire.

Appendices Due to Concerns Over the Quality of the Data Collected
APPENDIX A WSU 2014-19 STRATEGIC PLAN Appendix A: WSU Strategic Plan 2014-15 Strategic Plan 2014-2019 President Elson S. Floyd, Ph.D. Strategic Plan 2014-2019 Introduction The 2014-19 strategic plan builds on the previous five-year plan, recognizing the core values and broad mission of Washington State University. Goals and strategies were developed to achieve significant progress toward WSU’s aspiration of becoming one of the nation’s leading land-grant universities, preeminent in research and discovery, teaching, and engagement. The plan emphasizes the institution’s unique role as an accessible, approachable research institution that provides opportunities to an especially broad array of students while serving Washington state’s broad portfolio of social and economic needs. While providing exceptional leadership in traditional land-grant disciplines, Washington State University adds value as an integrative partner for problem solving due to its innovative focus on applications and its breadth of program excellence. The plan explicitly recognizes the dramatic changes in public funding that have occurred over the duration of the previous strategic plan, along with the need for greater institutional nimbleness, openness, and entrepreneurial activity that diversifies the University’s funding portfolio. In addition, the plan reaffirms WSU’s land-grant mission by focusing greater attention system-wide on increasing access to educational opportunity, responding to the needs of Washington state through research, instruction, and outreach, and contributing to economic development and public policy. While the new plan retains the four key themes of the previous plan, its two central foci include offering a truly transformative educational experience to undergraduate and graduate students and accelerating the development of a preeminent research portfolio.

NMIH Tour Post-Visit Lesson Plan GOAL Students will be better able to bridge the past and present through stories of people, ideas, and inventions. OBJECTIVE After participating in this post-lesson: • students will think critically about contemporary advancements in science, technology, engineering, and the arts • students will recognize how America –and much of the world—has changed since the Industrial Revolution • students will cultivate a desire to look for and invent solutions to common problems THEME Innovation S.T.E.A.M. INITIATIVE At NMIH we strive to use an interdisciplinary approach to educate our visitors—the general public and school groups alike—about our city’s unique history, the region’s industrial heritage, and the far- reaching impact of the local innovations, entrepreneurs, and workers. The following RESOURCES, MATERIAL LIST, ENRICHMENT SECTION, and DISCUSSION GUIDE can be used in any combination to meet the needs of the students and subject being taught in the classroom. It is not necessary to use the post lesson following your school visit to the National Museum of Industrial History, however, we find that students who participate in a post lesson are better able to synthesize the information they learned in the pre-lesson and through the interactive experiences they had during their visit to arrive at logical and well-informed conclusions about scientific principles and social history. Additionally, students who complete both a pre and post lesson have a deeper understanding of the content taught and are more likely to be able to apply the concepts they learned to future experiences. Additional lesson plans and discussion guides for use in the classroom are available upon request.

John Ripley Freeman 1855-1932
NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA BIOGRAPHICAL MEMOIRS VOLUME XVII—EIGHTH MEMOIR BIOGRAPHICAL MEMOIR OF JOHN RIPLEY FREEMAN 1855-1932 BY VANNEVAR BUSH PRESENTED TO THE ACADEMY AT THE AUTUMN MEETING, 1935 JOHN RIPLEY FREEMAN 1855-1932 BY VANNJJVAR BUSH John Ripley Freeman, distinguished here and abroad as a civil engineer, hydraulician and pioneering expert in fire pre- vention and control, was born on his father's farm, West Bridgton, Me., July 27, 1855, and died at his own home in Providence, R. I., October 6, 1932. His professional life of fifty-six years was crammed with useful and largely original work—eagerly undertaken, thoroughly and brilliantly com- pleted—which won for him the respect and liking of colleagues, the loyalty of co-workers, and grateful public appreciation. Fortunate in possessing a vigorous body and a penetrating mind, he used these talents with unremitting zest: there was no lost motion in the running of this rugged and nicely adjusted mechanism of muscle, heart and nerve, over which ruled a will tensed for sustained effort and an intelligence that united in- sight with precision and force. I le set a stiff pace for others, but spared not himself. If he exacted hard stints from his helpers, he inspired them, too, by enthusiasm and example; in the midst of a demanding job he kept no working hours, and scarcely knew how to call a day a day. Though the pres- sure of the drive was relentless, he stayed in the van through the toughest going. And to these qualities of character— industry and leadership—a third was added, integrity.

H UNSAKER 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 1954 NATIONAL ACADEMY OF SCIENCES WASHINGTON D.C. ELMER AMBROSE SPERRY 1860-1930 BY J. C. HUNSAKER Elmer Ambrose Sperry, inventor and pioneer in the field of applied electricity, was born to Stephen Decatur Sperry and his wife Mary Burst in Cortland, New York, October 12, i860, and died in Brooklyn, June 16, 1930.1 Richard Sperry, the first of the family to arrive in America, settled in 1634 just north of New Haven. In a cave on his farm he hid the Regicide Judges who condemned Charles I to death in the time of Cromwell. A ridge on the Sperry farm, recently tunneled for the Merritt Parkway, became the site of West Rock Park. Elmer Sperry's mother died at the birth of her only child and he was reared by his widowed aunt, Helen Sperry Willett. His father worked for the Cortland Wagon Company, whose wagons were driven up and down the seven valleys radiating from Cortland and were occasionally taken by Stephen Sperry as far as New York or Chicago. Young Sperry's inventive bent showed itself early. As a boy he built nutmeg graters, waterwheels, windmills and a tricycle that he could pedal on the railroad tracks, just ahead of the local freight, in exciting races to safety.

A 150-Year History of Mechanical Engineering at Lehigh
A 150-YEAR HISTORY OF MECHANICAL ENGINEERING AT LEHIGH Compiled by Stanley H. Johnson, Emeritus Professor A 150-YEAR HISTORY OF MECHANICAL ENGINEERING AT LEHIGH Compiled by Stanley H. Johnson, Emeritus Professor There was mechanical engineering education at Lehigh from the very beginning, but it has taken various forms over the first 150 years, as will be seen. This compilation was undertaken at the urging of Chairman Gary Harlow. Several faculty were kind enough to contribute reminiscences to the recent history, extending the material available from the “Brown and White” and Lehigh catalogs. There is no claim of comprehensive thoroughness. Whatever the sources offered that seemed interesting and contributed to a feeling of the flavor of life in the department was included. The arrangement is approximately chronological and the content tends toward gossip at times. I hope readers are kept interested and gain an appreciation of the significant role our department has played on campus from the very beginning, 150 years ago. The story divided naturally into four sections plus a brief history of mechanics prior to merger 1. The history of mechanical engineering education at Lehigh from the first full year of classes, 1866, until 1914, the beginning of World War I. Joe Klein became the first professor of mechanical engineering in 1881. Tau Beta Pi was founded at Lehigh in 1885. 2. The tumultuous interwar years, 1918-1941, brought rapid changes and financial uncertainty. The early faculty consisted of two professors of ME and one professor of machine design. James Ward Packard gave $1,000,000 for the purpose of erecting the laboratory that became Packard Lab.
