Carlos Graef Fernández (February 25, 1911 – January 13, 1988) was a Mexican physicist and mathematician. A graduate of the National Autonomous University of Mexico (UNAM) and the Massachusetts Institute of Technology (MIT), he was a founding member of the Mexican Mathematical Society and the Mexican Physical Society. He helped to establish the Tonantzintla Observatory and he later directed it. He received the National Prize for Arts and Sciences in 1970.
Donald Delbert Clayton (March 18, 1935 – January 3, 2024) was an American astrophysicist whose most visible achievement was the prediction from nucleosynthesis theory that supernovae are intensely radioactive. That earned Clayton the NASA Exceptional Scientific Achievement Medal (1992) for “theoretical astrophysics related to the formation of (chemical) elements in the explosions of stars and to the observable products of these explosions”. Supernovae thereafter became the most important stellar events in astronomy owing to their profoundly radioactive nature. Not only did Clayton discover radioactive nucleosynthesis during explosive silicon burning in stars but he also predicted a new type of astronomy based on it, namely the associated gamma-ray line radiation emitted by matter ejected from supernovae. That paper was selected as one of the fifty most influential papers in astronomy during the twentieth century for the Centennial Volume of the American Astronomical Society. He gathered support from influential astronomers and physicists for a new NASA budget item for a gamma-ray-observatory satellite, achieving successful funding for Compton Gamma Ray Observatory. With his focus on radioactive supernova gas Clayton discovered a new chemical pathway causing carbon dust to condense there by a process that is activated by the radioactivity.Clayton also authored a novel, The Joshua Factor (1985), a parable of the origin of mankind utilizing the mystery of solar neutrinos; a science autobiography and a memoir; and a history of the origin of each isotope, Handbook of Isotopes in the Cosmos (Cambridge Univ. Press, 2003).
Clayton died on January 3, 2024, at the age of 88.
Kenneth Marshall Watson (September 7, 1921 – August 18, 2023) was an American theoretical physicist and physical oceanographer.
Neil Clark Warren (born September 18, 1934) is an American clinical psychologist, Christian theologian, seminary professor and co-founder of the online relationship sites eHarmony and Compatible Partners.
In 1995, Warren and his son-in-law, Greg Forgatch, created Neil Clark Warren & Associates, a company which offers seminars and teaching tools based on Warren's books. In early 2000, they established eHarmony, an online compatibility matching service which gained two million users in its first three years. After retiring in 2007, Warren came out of retirement in July 2012, returning as the chief executive of eHarmony.
Brent David Ruben (born October 17, 1944) is a Distinguished Professor of Communication, Department of Communication, Rutgers School of Communication and Information. He also serves as Advisor for Strategy and Planning in the Office to the Executive Vice President for Academic Affairs, is Senior University Fellow in leadership and communication, and founder of the Rutgers Center for Organizational Leadership. Ruben is a member of faculties of Robert Wood Johnson School of Medicine and the Ph.D. Program in Higher Education in the Rutgers Graduate School of Education. Ruben's academic career has been devoted to advancing interdisciplinary and systemic approaches to the study of communication, and the application of these frameworks in cross-cultural, health, educational, organizational, and leadership contexts. He is author of more than 60 books and 150 journal articles and book chapters in these areas.
George E. Collins (January 10, 1928 in Stuart, Iowa – November 21, 2017 in Madison, Wisconsin) was an American mathematician and computer scientist. He is the inventor of garbage collection by reference counting[G60]
and of the method of quantifier elimination by cylindrical algebraic decomposition.[G75]He received his PhD from Cornell University in 1955. He worked at IBM, the University of Wisconsin–Madison (1966–1986) Ohio State University, RISC-Linz, Delaware University, and North Carolina State University.
Lily Brooks-Dalton (born August 18, 1987) is an American writer. She was born and raised in southern Vermont. Her first book, Motorcycles I've Loved: A Memoir, published in 2015 by Riverhead, was a finalist for the Oregon Book Award. Her first novel, Good Morning, Midnight, was published the next year by Random House, and it has been translated into half a dozen languages, with a film adaptation as The Midnight Sky in December 2020 starring and directed by George Clooney.Brooks-Dalton earned a BA at the University of Massachusetts Amherst and a MFA at Portland State University.
