	English-born American astronomer Eleanor Margaret Burbidge was the first woman to be appointed director of the Royal Greenwich Observatory. She was at the forefront in obtaining and interpreting quasar data and made notable contributions to astrospectroscopy, radio galaxies, masses and evolution of normal galaxies, and the chemical composition of stars. Dr. Burbidge served as assistant director and acting director of the Observatory of the University of London from 1948-51. In 1955 her husband, theoretical astrophysicist Geoffrey Burbidge, obtained a Carnegie fellowship for astronomical research at the Mount Wilson Observatory in California. Because women were then ineligible for such an appointment, she chose to accept a minor research post at the California Institute of Technology. In 1957 she became Shirley Farr Fellow and, later, associate professor at Yerkes Observatory at Williams Bay, Wisconsin. She also served as research astronomer and professor of astronomy at the University of California, San Diego (UCSD) before taking a leave of absence to serve as director of the Royal Greenwich Observatory in 1972. Her Greenwich duties did not come with the traditional honorary title of Astronomer Royal, which instead was given to a male astronomer, in another instance of discrimination against women in the astronomical community. A longtime champion of opportunities in science for women, she refused the Annie J. Cannon Prize from the American Astronomical Society (AAS) in 1972 because, as it was an award for women only, it represented for her another facet of the same discrimination. Her action led to the formation of a standing AAS committee for the status of women in astronomy. From 1979-88 Dr. Burbidge directed UCSD's Center for Astrophysics and Space Sciences, where she helped develop some of the Hubble Space Telescope's original instruments. She became a professor emeritus of the university in 1990. E. Margaret Burbidge died on April 5, 2020 in San Francisco, California at the age of 100.

	Jocelyn Bell Burnell is widely recognized as the individual responsible for the 1967 discovery of pulsars. With skill and perseverance she overcame the skepticism and resistance of her senior colleagues to make one of the most important and dramatic discoveries in 20th century astrophysics. In 2018 her essential role in the discovery was recognized by the Breakthrough Prize Foundation with a Special Breakthrough Prize. Bell Burnell donated the associated prize money to the Institute of Physics to support scholarships for individuals from underrepresented groups. Later in her career she worked in infrared, X-ray and gamma-ray astrophysics. More recently she turned her attention to education including the public understanding of science where according to the Royal Society, her contribution "has been uniquely valuable." The Royal Society web site refers to Jocelyn Bell Burnell as "one of the most influential scientists in the UK." She was elected to the American Academy of Arts & Sciences in 2018.

He is a Fellow of the Royal Society of London and a Founder Member of the Academy of Science of South Africa. He has been awarded the South African national Order of Mapungubwe, the Karl Jansky Lectureship of Associated Universities Inc and the NRAO, the Lifetime Achievement Award of the National Research Foundation, the Science for Society Gold Medal of the Academy of Science of South Africa and several honorary degrees. He was a Visiting Professor at Oxford University. He has a BSc Honours degree in physics from the University of the Witwatersrand and a PhD in radio astronomy from Cambridge University. During his PhD he published the Fanaroff-Riley classification of radio galaxy and quasar morphology with fellow student Julia Riley, which continues to be a basic classification of the jets which carry energy away from the accretion disks surrounding super-massive black holes in the centres of most galaxies. He left academia in 1976 to become a national organizer in South Africa of the nascent Metal and Allied Workers Union, one of the new non-racial unions then being organized in opposition to the legally-recognised unions which excluded Black workers, who had no rights under apartheid. He became a national secretary of the National Union of Metalworkers of South Africa in 1987. When Nelson Mandela became President after the first democratic election in 1994, he became Deputy Director General in the Office of the President and Head of the Office for the Reconstruction and Development Programme, government’s central programme to build the country after apartheid. He became Deputy Director General of the Secretariat for Safety and Security in 1997 and chaired the Integrated Justice System Board and the Inter-Departmental Committee for Border Control. He led the drafting of the new Firearms Control Act. He left government in 2000. He led the bid by South Africa, with eight other African countries, to host the world’s largest telescope, the Square Kilometre Array Radio Telescope. The bid was successful in 2012. The SKA South African team also designed and built the MeerKAT radio telescope, a world-leading telescope which has made major discoveries in the evolution of galaxies and clusters of galaxies and in pulsar and transient radio source discovery and timing, as a result of its unique sensitivity, timing accuracy and imaging quality. The MeerKAT will become part of the SKA Mid-Frequency Array in the late 2020s. SKA South Africa developed a world-leading Human Capital Development Programme, which enabled the development of a large and thriving radio astronomy science and technology community in South Africa from the initial five radio astronomers in 2003. It also trains scientists and engineers from the eight African partner countries. The SKA SA HCD programme led to the successful Development in Africa with Radio Astronomy (DARA) and the DARA Big Data programmes in partnership with the UK Government’s Newton Fund. He was an adviser to the Director of the South African Radio Astronomy Observatory, the successor to the SKA South Africa project. He has been appointed by the Minister for Trade, Industry and Competition to lead the development and implementation of a tripartite plan for the recovery and growth of the steel and steel products industries in South Africa.

	Owen Gingerich is a senior astronomer emeritus at the Smithsonian Astrophysical Observatory and Professor Emeritus of Astronomy and of the History of Science at Harvard University. In 1992-93 he chaired Harvard's History of Science Department. Professor Gingerich's research interests have ranged from the recomputation of an ancient Babylonian mathematical table to the interpretation of stellar spectra. In the past four decades Professor Gingerich has become a leading authority on the 17th-century German astronomer Johannes Kepler and on Nicholas Copernicus. His publications include a 600-page monograph surveying copies of Copernicus' great book De revolutionibus, for which he was awarded the Polish government's Order of Merit in 1981; later an asteroid was named in his honor. In 2006 he published God's Universe, a volume arguing that faith and science can coexist even in considerations of the nature of life. In 1984 he won the Harvard-Radcliffe Phi Beta Kappa prize for excellence in teaching. In June 2007 he was awarded the Prix Janssen by the French Astronomical Society. He has been a member of the American Philosophical Society since 1975. In June 2017 he received Benedict Polak Prize, which he described this way: "I have just returned from Poland, where I have received the Benedict Polak Prize, which I daresay no other APS member has ever heard of. Friar Benedict the Pole was drafted in 1245 as a translator-scholar to accompany a Papal group to visit the Khan of Mongolia. The present Benedict Polak Prize was established three years ago to honor explorers in any realm of human knowledge, and is to be given each year to a Polish citizen and to a foreigner. I received this year's prize for my Copernican researches. The Polish citizen prize went to my friend Jerzy Gassowski, the archaeologist who identified Copernicus' bones in an unmarked grave under the cathedral floor in Frombork. The prizes are given in Leczyca, a small village with the founding church in Poland and the church home of Benedict the Pole. It is hard to imagine that enough citizens of Leczyca would turn up for such an occasion, but actually people came from all over Poland. The president of Poland was not present in person, but sent a citation as well as a private and specific congratulatory letter to me."
