Hermann Mayer Salomon Goldschmidt was a German-French astronomer and painter who spent much of his life in France. He started out as a painter, but after attending a lecture by the famous French astronomer Urbain Le Verrier turned to astronomy. His discovery of the asteroid Lutetia in 1852 was followed by further findings and by 1861 Goldschmidt had discovered 14 asteroids. He received the Gold Medal of the Royal Astronomical Society in 1861 for having discovered more asteroids than any other person up to that time. He died from complications of diabetes.
William Lassell was an English merchant and astronomer. He is remembered for his improvements to the reflecting telescope and his ensuing discoveries of four planetary satellites.
Aden B. Meinel was an American astronomer. He retired in 1993 as a distinguished scientist at the Jet Propulsion Laboratory. He also held the rank of professor emeritus at the University of Arizona College of Optical Sciences. His research interests have included upper atmospheric physics, glass technology, optical design, instrumentation and space systems.
The David Dunlap Observatory (DDO) is an astronomical observatory site in Richmond Hill, Ontario, Canada. Established in 1935, it was owned and operated by the University of Toronto until 2008. It was then acquired by the city of Richmond Hill, which provides a combination of heritage preservation, unique recreation opportunities and a celebration of the astronomical history of the site. Its primary instrument is a 74-inch (1.88 m) reflector telescope, at one time the second-largest telescope in the world, and still the largest in Canada. Several other telescopes are also located at the site, which formerly also included a small radio telescope. The scientific legacy of the David Dunlap Observatory continues in the Dunlap Institute for Astronomy & Astrophysics, a research institute at the University of Toronto established in 2008.
J-John Kavelaars, better known as JJ Kavelaars, is a Canadian astronomer who was part of a team that discovered several moons of Jupiter, Saturn, Uranus, and Neptune. He is also a discoverer of minor planets and an investigator on the extended New Horizons mission, having aided in the discovery of 486958 Arrokoth.
Willem Hendrik van den Bos was a Dutch astronomer who worked at the Union Observatory in South Africa and became its director in 1941. He discovered nearly 3000 new double stars, made more than 71000 astronomical measurements and compiled a catalogue of Southern hemisphere double stars. He computed the orbits of more than 100 double stars using a method he invented and which later became the accepted standard.
The Canada–France–Hawaii Telescope (CFHT) is located near the summit of Mauna Kea mountain on Hawaii's Big Island at an altitude of 4,204 meters, part of the Mauna Kea Observatory. Operational since 1979, the telescope is a Prime Focus/Cassegrain configuration with a usable aperture diameter of 3.58 metres (11.7 ft).

The University of Toronto Southern Observatory (UTSO) was an astronomical observatory built by the University of Toronto at the Las Campanas Observatory in Chile. It hosted a single 60 cm Cassegrain telescope and a small cottage for the operators, located amongst the instruments funded by other organizations. The first observational runs started in 1971, and like many smaller instruments, it was later shut down in favor of a partial share in a much larger telescope in 1997. Although small by modern standards, the Southern Observatory nevertheless became famous for its role in the discovery of SN 1987A when UofT astronomer Ian Shelton spotted the supernova while observing with another little-used telescope at the site.
4230 van den Bergh (prov. designation: 1973 ST1) is a highly elongated Hildian asteroid and member of the Schubart family from the outer regions of the asteroid belt. It was discovered on 19 September 1973, by Dutch astronomer couple Ingrid and Cornelis van Houten at Leiden Observatory, on photographic plates taken by Dutch–American astronomer Tom Gehrels at the Palomar Observatory, California. The assumed carbonaceous C-type asteroid has a very long rotation period of 88 hours and measures approximately 37 kilometers (23 miles) in diameter. It was named for Dutch–Canadian astronomer Sidney Van den Bergh.
Víctor Manuel Blanco was a Puerto Rican astronomer who in 1959 discovered Blanco 1, a stellar cluster. Blanco was the second Director of the Cerro Tololo Inter-American Observatory in Chile, which had the largest telescope in the Southern Hemisphere at the time. In 1995, the 4-meter telescope was dedicated in his honor and named the Víctor M. Blanco Telescope; it is also known as the "Blanco 4m."
Nicholas Ulrich Mayall was an American observational astronomer. After obtaining his doctorate from the University of California, Berkeley, Mayall worked at the Lick Observatory, where he remained from 1934 to 1960, except for a brief period at MIT's Radiation Laboratory during World War II.
Sidney Carne Wolff is an American astrophysicist, researcher, public educator, and author. She is the first woman in the United States to head a major observatory, and she provided significant contributions to the construction of six telescopes. Wolff served as Director of the Kitt Peak National Observatory (KPNO) and the National Optical Astronomy Observatory (NOAO). She is a member of the International Astronomical Union's Division G: Stars and Stellar Physics.
