The Leonard Medal honors outstanding contributions to the science of meteoritics and closely allied fields. It is awarded by the Meteoritical Society. It was established in 1962 to honor the first President of the Society, Frederick C. Leonard. [1]
Carlyle Smith Beals, FRS was a Canadian astronomer.
Gabriel Auguste Daubrée MIF FRS FRSE was a French geologist, best known for applying experimental methods to structural geology. He served as the director of the École des Mines as well as the president of the French Academy of Sciences.
Grenville Turner was a British geochemist who was a research professor at the University of Manchester. He was one of the pioneers of cosmochemistry.
George Wetherill was a physicist and geologist and the director emeritus of the department of terrestrial magnetism at the Carnegie Institution of Washington, DC, US.
The Nier Prize is named after Alfred O. C. Nier. It is awarded annually by the Meteoritical Society and recognizes outstanding research in meteoritics and closely allied fields by young scientists. Recipients must be under 35 years old at the end of the calendar year in which they are selected. The Leonard Medal Committee recommends to the Council candidates for the Nier Prize.
The Meteoritical Society is a non-profit scholarly organization founded in 1933 to promote research and education in planetary science with emphasis on studies of meteorites and other extraterrestrial materials that further our understanding of the origin and history of the Solar System.
Klaus Keil was a professor at the School of Ocean and Earth Science and Technology (SOEST) at the University of Hawaiʻi at Mānoa. He was the former Director of the Hawaiʻi Institute of Geophysics and Planetology. He was also the former director of the University of New Mexico Institute of Meteoritics. Klaus pioneered the use of the electron microprobe to study meteorite samples. He was one of the co-inventors of the energy dispersive X-ray spectrometer.
Harry "Hap" Y. McSween Jr. is Chancellor's Professor Emeritus of Planetary Geoscience at the University of Tennessee at Knoxville. He has published papers and popular books about meteorites and planetary exploration, and textbooks on geochemistry and cosmochemistry.
Brian Harold Mason was a New Zealand geochemist and mineralogist who was one of the pioneers in the study of meteorites. He played a leading part in understanding the nature of the Solar System through his studies of meteorites and lunar rocks. He also examined and classified thousands of meteorites collected from Antarctica.
The Barringer Medal recognizes outstanding work in the field of impact cratering and/or work that has led to a better understanding of impact phenomena. The Barringer Medal and Award were established to honor the memory of D. Moreau Barringer Sr. and his son D. Moreau Barringer Jr. and are sponsored by the Barringer Crater Company. The medal is awarded by the Meteoritical Society. The senior Barringer was the first to seriously propose an impact origin for the crater that now bears his name.
Frederick Charles Leonard was an American astronomer. As a faculty member at the University of California, Los Angeles, he conducted extensive research on double stars and meteorites, largely shaping the university's Department of Astronomy. He received his undergraduate degree from the University of Chicago in 1918 and his PhD in astronomy from the University of California, Berkeley in 1921. Leonard was an astronomer from his teenage years, founding the Society for Practical Astronomy in 1909. In 1933 he founded The Society for Research on Meteorites, which later became known as the Meteoritical Society. He was its first president and was the Editor of the Society's journal for the next 25 years. The Society instituted the Leonard Medal in 1962, its premier award for outstanding contributions to the science of meteoritics and closely allied fields.
Alastair G. W. Cameron was an American–Canadian astrophysicist and space scientist who was an eminent staff member of the Astronomy department of Harvard University. He was one of the founders of the field of nuclear astrophysics, advanced the theory that the Moon was created by the giant impact of a Mars-sized object with the early Earth, and was an early adopter of computer technology in astrophysics.
Robert M. Walker was an American physicist, a planetary scientist, the founder and director of McDonnell Center for the Space Sciences at Washington University in St. Louis, noted for his co-discovery of the etchability of nuclear particle tracks in solids, as well as his conjecture that meteorites and lunar rocks contain a record of the ancient radiation history of various stars including the Sun. Asteroid 6372 was named Walker in his honor by the International Astronomical Union. Walker was a member of the National Academy of Sciences. Walker was also a fellow of the American Physical Society, the American Geophysical Union, the Meteoritical Society and the American Association for the Advancement of Science. He was also a founder and the first president of Volunteers in Technical Assistance (VITA).
The Grant Meteorite is a meteorite that was discovered in the Zuni Mountains, about 45 miles (72 km) south of Grants, New Mexico. It was unearthed in 1929 although the date of its original groundfall is unknown.
Ursula Bailey Marvin was an American planetary geologist and author who worked for the Smithsonian Astrophysical Observatory.
Robert Norman Clayton was a Canadian-American chemist and academic. He was the Enrico Fermi Distinguished Service Professor Emeritus of Chemistry at the University of Chicago. Clayton studied cosmochemistry and held a joint appointment in the university's geophysical sciences department. He was a member of the National Academy of Sciences and was named a fellow of several academic societies, including the Royal Society.
Sara Samantha Russell is a professor of planetary sciences and leader of the Planetary Materials Group at the Natural History Museum, London. She is a Fellow of the Meteoritical Society and of the Royal Astronomical Society.
Hiroko Nagahara is a Japanese cosmochemist and astromineralogist whose research studies the chemical composition and formation of chondrules, the molten mineral droplets that accrete to form asteroids and meteoroids. She is a fellow of the Earth–Life Science Institute of the Tokyo Institute of Technology, a professor emerita of Tokyo University, and a former president of the Meteoritical Society.
Katharina Lodders is a German-American planetary scientist and cosmochemist who works as a research professor in the Department of Earth and Planetary Sciences at Washington University in St. Louis, where she co-directs the Planetary Chemistry Laboratory. Her research concerns the chemical composition of solar and stellar environments, including the atmospheres of planets, exoplanets, and brown dwarfs, and the study of the temperatures at which elements condense in stellar environments.
