Martin Schwarzschild (1912 - 1997)

Martin Schwarzschild, Higgins Professor of Astronomy, Emeritus, at Princeton University, died on 10 April 1997 following a heart attack, just ten days after the death of his close personal and scientific friend, Lyman Spitzer. They were together at Princeton for half a century; they made Princeton a truly unique place for astrophysics; and they kept it unique for decades. Their presence was strongly felt all the way to the end, and it is very hard to imagine how we shall continue without them. Martin would have been 85 on May 31.

Leon William Schroeder (1921 - 1995)

Leon W. Schroeder, for many years the astronomer at Oklahoma State University, was born 25 January 1921 in Guthrie, OK and graduated from Stillwater High School in 1937. His college work at Oklahoma A&M College was interrupted by flight training and, eventually, teaching at the No. 3 British Flying Training School in Miami, OK. He retained his pilot's license and frequently provided transportation for members and visitors of the Oklahoma State physics department.

Carl Sagan (1934 - 1996)

American astronomy lost its clearest and most colorful public voice with the death of Carl Sagan on 20 December 1996, at Fred Hutchinson Cancer Research Center in Seattle, Washington, as an immediate result of pneumonia, secondary to myelodysplasia. A native of Brooklyn, New York (born 9 November 1934), Sagan graduated in 1951 from Rahway High School, Rahway, New Jersey (which now boasts a Carl Sagan Science Wing, dedicated in 1991).

Jurgen H. Rahe (1939 - 1997)

Dr. Jurgen H. Rahe, Director for Solar System Exploration in NASA's Office of Space Science, was killed in an act of staggering randomness on 18 June 1997 when a 5-foot diameter oak tree fell during a storm, crushing his car. Jurgen is remembered as a respected, effective, and well-liked scientist and administrator, but above all as a gracious and gentle man. He is mourned by his wife, Hazel, daughter Isabell, two brothers in Germany, other family members, and countless colleagues and friends.

Edward Mills Purcell (1912 - 1997)

An experimental physicist who shared the 1952 Nobel Prize in Physics with Felix Bloch for their independent discovery of nuclear magnetic resonance, Purcell also contributed substantially to both observational and theoretical astrophysics. He shared the 1988 Tinsley Prize of the American Astronomical Society with Harold I. Ewen for their independent discovery of the emission of the HI 21-cm line by interstellar hydrogen. Ewen and Purcell's discovery was published in Nature (168, 356, 1951), along with reports from J. Pawsey in Australia and J.

Jacobus A. Petterson (1946 - 1996)

Jacobus ("Koos") Petterson, best known in the astronomical community for his analysis of X-ray binary systems, died at his home in Carrollton, Georgia on 30 May 1996. Petterson was born in Rotterdam, The Netherlands, on 16 August 1946 and received an MS in Engineering Mathematics in 1970 from the Technical University in Delft for work with A. J.

Thomas H. Markert (1948 - 1996)

Thomas H. Markert died on 19 June 1996, after a long battle with cancer. Tom received his BS from Caltech in 1970 and his PhD from MIT in 1975, both in physics, joining the AAS the next year. He remained at MIT throughout his career, first as a member of the research staff and then as Principal Research Scientist in the Center for Space Research.

Jerome Kristian (1934 - 1996)

Jerome Kristian (called Jerry, by his friends) was born 5 June 1934, in Wilwaukee, Wisconsin, and died 22 June 1996 in an ultralight airplane accident. He attended the University of Chicago, obtaining MS and PhD degrees (Physics), the latter in 1962 with a thesis on "Hydromagnetic Equilibrium of a Fluid Sphere," supervised by S. Chandrasekhar and published in three Astrophysical Journal papers in 1963-64. While at the University of Texas (1962-64) as an instructor, Kristian collaborated with R. K.

James Jay Klavetter (1960 - 1997)

Our colleague and friend, James Jay Klavetter, Assistant Professor of Astronomy at California State University, Sacramento, died of leukemia on 24 February 1997, at his home in Sacramento. Jim is survived by his parents Elaine and Floyd, sister Mary, and brothers Elmer and Floyd. Jim will be remembered as an inspired individual whose fascination with Nature shaped his life; he studied astronomy professionally and spent his leisure time outdoors with his dogs and his friends.

Igor Jurkevich (1928 - 1996)

Igor Jurkevich was born in Bmo, Czechoslovakia on 16 September 1928 and completed his secondary education at the Russian Gymnasium of the Displaced Persons' camp in Schleissheim, Germany, outside Munich. After World War II, he came to the United States and received his BS in Mathematics at Dennison and graduate degrees in Physics (1955) and Astronomy (1964) at the University of Pennsylvania.

Allan S. Jacobson (1932 - 1997)

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 Henry Barrows Irwin (1909 - 1997)

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 L. Golden (1940 - 1995)

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 Carl Fry (1892 - 1991)

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.

Robert Henry Dicke (1916 - 1997)

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).
