Robert E. Davies (1919 - 1993)

Bob Davies passed from active to Emeritus status at the University of Pennsylvania in 1990.  A skillful caver, mountain climber, and white-water adventurer, he died of a coronary attack while on a climbing trip in rural Scotland.

 Bob was born in Lancashire, U.K. of working-class parents and earned his D.Sc. from the University of Manchester and Ph.D. from Sheffield.  Having been on the faculties of Sheffeld and Oxford, he emigrated to the U.S. in 1955.  Although remaining a British citizen, he spent the rest of his career at Pennsylvania.

Jan Hendrik Oort (1900 - 1992)

An obituary for Jan Oort, astronomer axtraordinaire and leader of Dutch astronomy since the 1920's has appeared in the Publications of the Astronomical Society of the Pacific, Vol. 105, pp. 681-5 (by A. Blaauw and M. Schmidt). An excellent collection of papers on Oort's life and work is found in Oort and the Universe, edited by H. van Woerden, W. N. Brouw, and H. C. van de Hulst (1980). An autobiographical article is available in the Annual Reviews of Astronomy and Astrophysics, Vol 19, p. 1 (1981).

Gerson Goldhaber (1924 - 2010)

Gerson Goldhaber was a leading particle physicist who turned his attention to cosmology in the latter part of career. He was the first person to assert from his interpretations of the data, and then report in professional meetings, evidence for the existence of Dark Energy. The evidence came from his study of supernova in the Berkeley Supernova Cosmology Project. In the words of Nobel laureate Sheldon Glashow, “His seminal contributions to our understanding of the smallest structures of Nature (particle physics) and to the largest (cosmology) have been truly remarkable.

Gordon James Fraser MacDonald (1929 - 2002)

Gordon J. F. MacDonald was born in Mexico in 1929, the son of a Scottish accountant. He never revealed to me how he managed to make the transition from schooling in Mexico to a highly successful student career at Harvard, ending with a PhD in 1954. I met Gordon first in 1959, in the home of Walter Munk, having been invited there specifically to meet this outstanding post doc, who had written a book together with Walter, The Rotation of the Earth. This is not a trivial subject, as I knew, having worked in this field before.

Christof Litwin (1949 - 2001)

Christof Litwin, a theoretical physicist with broad interests ranging from field theory to plasma physics and astrophysics, passed away suddenly and unexpectedly on 4 October 2001, from complications arising from surgery for oral cancer. Christof was a senior scientist at the University of Chicago, working within the Department of Astronomy and Astrophysics and the Center for Astrophysical Thermonuclear Flashes.

Karen Lorraine Harvey (1942 - 2002)

Two days after completing her last research paper, Karen Lorraine Harvey died of complications associated with cancer on 30 April 2002. She earned international recognition for her wide-ranging work on solar magnetic fields and solar activity. Her friends knew her as a warm, generous, energetic woman who admirably balanced her scientific achievements with devotion to family, service to the professional community, and fostering the careers of younger colleagues.

Jerome Mayo Greenberg (1922 - 2001)

J. Mayo Greenberg, a leading experimental astrochemist and expert on cometary structure and composition, died of pancreatic cancer in his home in Leiden, The Netherlands, on 29 November 2001. Though born in Baltimore, Maryland on 14 January 1922, and educated at Johns Hopkins University, Greenberg had immigrated to The Netherlands in 1975, and it was there that his cometary expertise matured.

John Mason Grant (1912 - 2002)

Jack M. Grant, as he preferred to be known, a long-time Canadian meteor astronomer, passed away in Orillia, Ontario on 5 March 2002. His father, Lewis John Mason Grant was an artist, while his mother, Daisy Constance Hilda née White Grant, devoted herself to maintaining the household. Lewis was independently wealthy; a family fortune had been amassed farming indigo in India during the period of Queen Victoria’s extended mourning and his modest inheritance was sufficient to support the family.

Edward Ryant Dyer Jr. (1918 - 1999)

Edward Ryant ‘‘Ned’’ Dyer, Jr. was the son of Rev. Edward Ryant Dyer, an Episcopal missionary and clergyman. His mother, Dr. Ann (nèe Humphreys) Dyer, studied medicine and obtained a medical degree. She met his father when they both were missionaries in China in 1913. Ned was born in Wuxi, China, on 1 February 1918 and was raised there for the first ten years of his life. As a child, Dyer developed an interest in astronomy from books in his father’s library, especially those by James Jeans and Arthur Eddington.

Lawrence Dunkelman (1917 - 2002)

Lawrence Dunkelman was a pioneer in the development of ultraviolet detectors and optical materials for use in scientific research. He applied these devices to astronomical and geophysical problems and played a significant role in developing the techniques and procedures necessary to make scientific optical measurements in space. Larry died in Tucson, Arizona on 27 January 2002.

David Q. Wark (1918 - 2002)

David Q. Wark, a research meteorologist at the National Environmental Satellite, Data, and Information Service of the National Oceanic and Atmospheric Administration (NOAA/NESDIS) and its predecessor organizations for 55 years, died of cancer 30 July 2002. He will be long remembered for his seminal contributions to the weather satellite program.

Leon Van Speybroeck (1935 - 2002)

Leon Van Speybroeck, a master designer of X-ray telescope mirrors and the telescope scientist for the Chandra X-ray Observatory, died in Newton, Massachusetts, on 25 December 2002, shortly after learning that he had metastatic melanoma. Leon was born on 27 August 1935 in Wichita, Kansas. His father, Paul, was Assistant Treasurer and head of the accounting department at Beech Aircraft, and his mother, Anna Florence (Utley), was a homemaker. Both parents died in 1996.
