Ilkka Liede (1947 - 1992)

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 (1905 - 1992)

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 (1906 - 1993)

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.

Goro Ishida (1924 - 1992)

Goro Ishida, retired astronomer from the Tokyo Astronomical Observatory and President of the Herschel Society of Japan, died of a heart attack on the 27th of July, 1992 while visiting a temple on an island in Lake Biwa. He is survived by his wife Kazuko and sons Juro and Saburo.

Sol H. Genatt (1921 - 1992)

Sol Genatt was for thirty years an astronomer for several federal agencies.  Born in New York City, he was an aerial navigator during World War II for the US Army Air Corps. He obtained a B.A. in Astronomy at Cornell University in 1947 and began work in the Nautical Almanac Office of the US Naval Observatory. Later he worked in the time Service Division field station in Richmond, Florida, observing with a photographic zenith tube. During the 1950s he also worked in the Research and Analysis Branch of the US Army Map Service under John A. O'Keefe.

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.
