the stellar evolution, accretion
discs, and gamma ray bursts. Paczyński was born on 8 February 1940
in Vilnius, Lithuania, to a lawyer and a teacher
of Polish literature. In 1945
his family chose to leave for Poland and settled in Kraków, and then in 1949 in Warsaw. At the age of 18, Paczyński published his first scientific
article in Acta Astronomica.
Between 1959 and 1962 he studied astronomy at the University of Warsaw. Two
years later he received a doctorate under the tutelage Zonn. In 1962
Paczyński became a member of the Centre of Astronomy of the Polish Academy of Sciences,
where he continued to work for nearly 20 years. In 1974 he received
habilitation and in 1979 became a professor. Thanks to his works on theoretical
astronomy, at the age of 36 he became the youngest member of the Polish Academy
of Sciences. In
1981 Paczyński visited the United States, where he gave a series of lectures at Caltech to former interns at his Warsaw-based institute.
After the introduction of the Martial Law in Poland he
decided to stay abroad. He was the Lyman Spitzer Jr. Professor of Astrophysics at Princeton University. Paczyński
was the initiator of Optical Gravitational
Lensing Experiment (OGLE, led by Andrzej Udalski of Warsaw University Observatory)
and All Sky Automated Survey (ASAS,
created together with Grzegorz Pojmański). His
new methods of discovering cosmic objects and measuring their mass by
using gravitational lenses gained
him international recognition, and he is acknowledged for coining the
term microlensing. He was
also an early proponent of the idea that gamma-ray bursts are at cosmological distances. His
research concentrated on stellar evolution, gravitational lensing and gravitational microlensing, variable stars, gamma-ray bursts, and galactic
structure. In 1999, he became the first astronomer to receive all
three major awards of the Royal Astronomical Society,
by winning the Gold Medal,
having won the Eddington Medal in
1987 and the George Darwin Lectureship in
1995. He
was honoured with the title of doctor honoris causa by Wrocław University in
Poland (on June 29, 2005) and Nicolaus Poland (on September 22, 2006). In January 2006
he was awarded Henry Norris Russell
Lectureship of the American Astronomical Society, "for his highly original
contributions to a wide variety of fields including advanced stellar evolution,
the nature of gamma ray bursts, accretion in binary systems, gravitational
lensing, and cosmology. His research has been distinguished by its creativity
and breadth, as well as the stimulus it has provided to highly productive
observational investigations". He died of brain cancer on April 19, 2007 in Princeton, New Jersey.
