Cornelis Zwaan (1928 - 1999)

Comelis ("Kees") Zwaan was a well-known solar physicist at Utrecht University in The Netherlands. Together with his graduate students he also ventured out to other cool stars, concentrating on their magnetic activity. He was a member of the AAS and the Solar Physics Division and had close ties with many American astrophysicists. He died from cancer in his house at Doorn, The Netherlands on June 16, 1999. He had had major surgery in 1998, but recovered so fast that we and his other friends expected to have him with us much longer. The end came far too soon.

Leonida Rosino (1915 - 1997)

Leonida Rosino, Professor emeritus of Astronomy at the University of Padua and former Director, for 30 years, of the Padova and Asiago Observatories, died in Padova on July 31, 1997, at the age of 81. Born in Treviso (Italy) on September 19, 1915, Rosino receive his degree in physics at the University of Padova. His advisor was Bruno Rossi, then Director of the Padova Physics Institute.

He then spent the first 15 years of his career at the University of Bologna before moving back to Padova.

Daniel M. Popper (1913 - 1999)

Daniel Magnes Popper was born at Oakland, California on 17 August 1913 into an assimilated Jewish family that had already provided several California community leaders. He earned degrees at the University of California, Berkeley, an AB in 1934 and a PhD in 1938, defending a dissertation on Spectrophotometry of Nova Lacertae 1936, supervised by Arthur B. Wyse. The published version appeared in Astrophysical Journal, though Dan said many years later that he would have preferred publication in Lick Observatory Bulletins.

Paris Marie Pişmiş (1911 - 1999)

On August 1st, a cherished teacher and friend, Paris Pişmiş, passed away. During her lifetime Pişmiş published more than 120 research articles on various topics of astrophysics. Her primary interest was galactic structure. She carried out some of the first photometric observations of young stellar clusters and discovered three globular clusters and 20 open clusters. She also studied the effects of interstellar absorption in stellar associations on the observed stellar distribution.

William McCrea (1904 - 1999)

Sir William Hunter ('Bill') McCrea, doyen of British astronomy, held in respect and affection by all generations, died peacefully on April 25, at the age of 94. McCrea was born in Dublin, the eldest child of a schoolmaster. His parents were strict members of the Plymouth Brethren, but by the age of eighteen he had become a confirmed Anglican, a faith he retained all his life.

Barry M. Lasker (1939 - 1999)

On 10 February 1999, Barry M. Lasker died suddenly following a heart attack. Barry was an astronomer for almost 40 years, playing an important role in the creation of two of the world's most highly-respected observatories, the Cerro Tololo Inter-American Observatory in Chile, and the Space Telescope Science Institute. His work on the Guide Star Catalog and the Digitized Sky Survey significantly influenced the entire field of observational astronomy.

Arthur A. Hoag (1921 - 1999)

Art Hoag was a member of several professional organizations including the IAU and the AAS. He served as an AAS Councilor from 1966 to 1969 and Vice Presiderit from 1974 to 1976. He was born January 28, 1921, in Ann Arbor, Michigan, and died July 17, 1999, in Tucson, Arizona, following a brief illness. He is survived by his wife, Marge; his two children, Stefanie and Tom; his three grandchildren and one great-grandchild.

Louis C. Green (1911 - 1999)

Louis Green was born in Macon, Georgia in 1911 and joined the faculty of Haverford College in 1941. For over 50 years, as Professor of Astronomy and College administrator, he played a central role in the life of the College and of its faculty, and inspired generations of students. Louis died on April 10, 1999.

Patrick J. Fleming (1938 - 1998)

Patrick Fleming, who died on the 4th of July 1998, was a man respected alike for his professionalism and his other cultural pursuits.

Pat was a true Dubliner, coming from the North Circular Road area.

He was born in January 1938 and received a Leaving Certificate from O'Connell's c.B.S. in 1956 and a bachelor's degree in Mechanical Engineering from University College Dublin in 1961. Graduate apprenticeship at Parsons-Reyrolle, Durham (England) qualified him for chartered membership of the Institution of Mechanical Engineers.

Charles Anthony Federer Jr. (1909 - 1999)

Together with his wife, Helen, Charlie Federer (who died September 28, 1999) founded Sky & Telescope. The impetus came from Harvard College Observatory director Harlow Shapley, who suggested the Federers come to Cambridge and meld two troubled magazines — The Sky (then produced at New York's Hayden Planetarium) and The Telescope (produced at HCO). Shapley provided office space for the enterprise, and S&T remained under Harvard's wing until it outgrew the available facilities. The staff moved to its present quarters in 1958.

Rebecca Anne Elson (1960 - 1999)

Rebecca A. W. Elson, an astronomer whose work on dense star clusters significantly advanced our understanding of cluster dynamics and stellar evolution, died on May 19, 1999, from non-Hodgkins lymphoma at the age of 39. She was a published poet, a creative researcher, and a colleague of extraordinary insight and warmth. Her contributions to our field, and to those who work in it, will be sorely missed.

Guenter E. Brueckner (1934 - 1998)

After a valiant, 9-month struggle with pancreatic cancer, Guenter Brueckner died on 11 July 1998 in Fairfax, Virginia, at the age of 63. He had spent 31 years of his scientific career at the Naval Research Laboratory (NRL), first as Head of the Solar Spectroscopy Section in the Rocket Spectroscopy Branch under Dr. Richard Tousey and then as the Head of the Solar Physics Branch, one of the two solar physics groups created when Tousey retired. Guenter was recognized as a very effective leader in developing advanced instrumentation to address problems in solar physics.

William Blitzstein (1920 - 1999)

William Blitzstein, a modern pioneer in stellar radiometry, died February 27, 1999. Born of immigrant parents, he went to Philadelphia public schools and by his late teens had become the person of choice to silver mirrors for Philadelphia amateur astronomers, an early indication of the observer-instrumentalist he was to become. He graduated from the University of Pennsylvania as a physics major in 1941 and received his PhD in astronomy, also from Penn, in 1950 under Newton Pierce and Charles Olivier.

Jeffrey Alan Willick (1959 - 2000)

Jeff Willick, 40, assistant professor of physics at Stanford University, was tragically killed by a runaway car while working at a coffee-shop on June 18, 2000. Jeff was an observational cosmologist who had done important work in mapping the peculiar velocity field of galaxies and comparing the results with the large-scale distribution of galaxies. He is survived by his wife, Ellen Schneider, and three children, Jason, Emily, and Julia.
