Bohdan Paczyński

Bohdan Krzysztof Paczyński (also spelled Paczynski; Polish: [ˈbɔxdan paˈt͡ʂɨɲski]; 8 February 1940 – 19 April 2007) was a Polish astronomer and astrophysicist. Educated at the University of Warsaw, he became the Lyman Spitzer Jr. Professor of Astrophysics at Princeton University. Paczyński is widely recognized for his highly original theories and research in the fields of cosmology, stellar evolution, accretion disks, the nature of gamma ray bursts, and time-domain astronomy, which reshaped modern understanding of high‑energy astrophysical phenomena and opened new observational pathways for studying distant objects in the universe. He was instrumental in founding the Nicolaus Copernicus Astronomical Center (CAMK) in Warsaw and launching the Optical Gravitational Lensing Experiment (OGLE), one of the most efficient photometric sky survey projects in the history of observational astronomy. Paczyński was the recipient of numerous awards and honours for his contributions to science such as the Eddington Medal (1987), the Henry Draper Medal (1997), the Gold Medal of the Royal Astronomical Society (1999), and the Order of Polonia Restituta (2007). He was a member of many learned societies including the Polish Academy of Sciences, the Royal Astronomical Society, and the National Academy of Sciences.
