Although Allan S. (Bud) Jacobson will be remembered by many of us for his pioneering work in nuclear gamma ray spectroscopy, his life and career were unusually rich. His service in the Air Force kindled a lifelong interest in military history and war games; his beautiful bass voice led him to an early career in show business; and his love of art resulted in the development of award-winning software for the visual display of scientific data. All who knew him will also remember his banjo playing and singing, which enlivened long balloon field trips and numerous social events.
John B. Irwin died of lymphoma cancer in Tucson, Arizona on 20 April 1997. He was born in Princeton, New Jersey, on 7 July 1909, the son of Frank and Mary (Barrows) Irwin. His father was later professor of mathematics at University of California, Berkeley. He attended elementary and high schools in Berkeley and received a BSc in mechanical engineering in 1933 and his PhD in astronomy in 1946 from UCB. Much of his graduate work was done at Lick Observatory, starting in 1941, under the direction of Art Wyse and Director William H.
Robert Herman, L.P. Gilvin Centennial Professor in the Department of Civil Engineering and staff member of the Center for Statistical Mechanics at the University of Texas, Austin, died 13 February 1997.
Professor Robert L. Golden of New Mexico State University, Las Cruces, died on 7 April 1995 after a brief illness. He was director of the Particle Astrophysics Laboratory and taught classes in electrical engineering. He was well known not only for his jubilant outgoing personality but also for the discovery of anti-protons in galactic cosmic rays and research into the properties of cosmic ray electrons (of both charges).
Thornton C. Fry was an industrial mathematician, probably the first to head a division devoted to the subject, initially at Western Electric Company (1916-1924) and later as part of Bell Telephone Laboratories. He was born in Findlay, Ohio on 7 January 1892, and received degrees from Findlay College (AB 1912, honorary DSc 1958) and the University of Wisconsin (MA 1913, PhD 1920 in mathematics, physics, and astronomy). He was involved in government scientific work in both the world wars, during the latter serving on a small committee with Edward J.
Isadore (Ira) Epstein, Professor Emeritus of Astronomy at Columbia University, died 17 September 1996, at the age of 76. He was an early researcher in the modem theory of stellar structure, and carried out important observatory site surveys in the southern hemisphere.
Robert H. Dicke, who made fundamental and lasting contributions to radio astronomy, solar physics, gravitational physics, and cosmology, died in Princeton on 4 March 1997. He is survived by his wife, Annie, whom he married in 1942 and three children. Dicke held the Cyrus Fogg Brackett professorship of physics from 1957 to 1975 and the Albert Einstein professorship of science from 1975 to 1984 (emeritus 1984-97).
Louis Berman, astronomer and teacher, was born in London, England on 21 March 1903, the son of George and Jennie Berman, recent immigrants from Lithuania, then part of Russia. When Louis was three, the family moved to St. Paul, Minnesota, where he attended public schools and the University of Minnesota. He earned his AB degree in 1925, his AM in 1927, and published several short papers on his visual double-star measurements, an asteroid orbit, and a comet orbit.
Jeno Barnothy, an outstanding pioneer of cosmic ray research and noted astrophysicist, died on 11 October 1996 at the age of 92 in Evanston, Illinois. He was born on 28 October 1904 in Kassa, Hungary (now Slovakia) and received his PhD in 1939 at the Peter Pazmany (now Loránd Eötvös) University, Budapest, Hungary. He was awarded of merit of the Hungarian Academy of Sciences in 1939 and the Eötvös Order in 1948.
On May 1, 1992, Professor Emeritus of Astronomy Robert J. Wood died suddenly at age 75. Central Florida lost one of its great teachers of astronomy. He was the designer of Astronaut Hall and the professor of astronomy at Brevard Community college, Cocoa, Florida. Many thousands of students in the Cape Canaveral area went through his famous classes from 1964 until his retirement in 1984.
After a long fight against prostatic cancer, Clayton A. Smith died on May 27th, 1993. His illness was first diagnosed in the early 1980’s, but a combination of his otherwise good health, careful medical treatment and a long determination on his part to remain active as long as possible gave Clayton many additional years of productive life.
Obituaries for Nicholas Mayall, extragalactic astronomer on the staffs of Lick and Kitt Peak Observatories, will appear in the Yearbook – The American Philosophical Society and in the Biographical Memoirs of the National Academy of Sciences.
An obituary for Harold Masursky, planetary geologist and longtime staff member at the US Geological Survey in Flagstaff, will appear in approximately the 1994 issue of Geological Society of America’s Memorials.
Herman Lowell obtained his Masters Degree in Physics at Columbia University in 1939 and spent most of his career at the NACA/NASA Lewis Research Center in Cleveland, Ohio (1943-60), NASA Headquarters (1960-65), and various Defense Department contractors thereafter. At Lewis he specialized in computational solutions to fluid flow equations; later, he helped develop large database computer systems.
Research Professor Ilkka Liede died on the 29th of July, 1992. A great number of colleagues and fellow employees in Finland and abroad share the grief of his family and relatives. The feeling of loss is strong among the personnel of several Finnish and foreign research institutes who had come to know him for his efficiency, friendliness, and analytical intellect.
Eugene Leimanis, applied mathematician and celestial mechanician, was a longtime member of the Department of Mathematics of the University of British Columbia in Vancouver, BC. He was born in Koceni, Latvia, the son of a teacher, and obtained a Masters Degree and First Prize in Mathematics in 1929 at the University of Latvia. During the 1930s he held a number of positions on the Unviersity’s faculty, the last being Docent of Analytical Mechanics and Theoretical Astronomy. After World War II he held several temporary positions and in 1947 obtained a Ph.D.
Pierre Lacroute passed away on 14 January 1993, a few days before reaching the age of 87. In 1946, shortly after the end of World War II, he was appointed Director of Strasbourg (France) Astronomical Observatory (succeeding André Danjon who was then taking up the directorship of Paris Observatory). Pierre Lacroute stayed in this position until his retirement in 1976. During the same period, he was also Professor at the Faculty of Sciences of Strasbourg Louis Pasteur University. He served also as Dean of this Faculty.
