In Memoriam
Charlie Tolbert (1936-2025)
A beloved educator and colleague, remembered by tens of thousands of University of Virginia alumni for his legendary astronomy lectures.
Charles (Charlie) Ray Tolbert, Emeritus Professor of Astronomy at the University of Virginia, passed away peacefully surrounded by his family on December 4, 2025, at the age of 89.
Charlie was born on November 14, 1936, to Ray and Mary Tolbert in Van, West Virginia, and was raised in Richmond, Virginia. He attended Fox Elementary School, Binford Junior High School, and Thomas Jefferson High School. He earned his B.S. in Physics from the University of Richmond in 1958, followed by graduate study at Vanderbilt University, where he received an M.S. in 1960 and a Ph.D. in Physics–Astronomy in 1963.
Charlie began his academic career as a postdoctoral researcher at the University of Groningen in the Netherlands, followed by three years as a scientific officer (roughly equivalent to an assistant professor). During this period, he met and married his wife, Carla. In 1967, at the invitation of department chair—and eventual lifelong friend—Larry Fredrick, Charlie and Carla moved to Charlottesville, where he joined the newly revitalized Astronomy Department at the University of Virginia (UVa) and launched a faculty career that would span more than four decades. Very early in his tenure, and for much of it thereafter, he served as Assistant Department Chair and, on occasion, as Acting Department Chair.
Tolbert’s early research encompassed both optical and radio astronomy. His Vanderbilt doctoral work, under Robert Howie Hardie and Arnold Heiser, was a photoelectric UBV study of wide binary stars using the Seyfert 24-inch telescope at Dyer Observatory. As a graduate student he also conducted UBV studies of variable stars and B stars in the Orion Belt region. His move to the Netherlands marked a transition to radio astronomy, where he participated in the Groningen–Leiden survey and other 21-cm studies using the 25-meter Dwingeloo radio telescope. He contributed to the early identification and mapping of high-latitude Intermediate and High Velocity Clouds and became well known for his research in this subject.
This research included collaboration with Adrian Blaauw, a relationship that proved instrumental in Tolbert’s eventual appointment at UVa. Beginning in the 1960s, Blaauw had initiated a project combining proper motions measured with the McCormick 26-inch refractor with Strömgren photometry for stars near the North Galactic Pole, aimed at characterizing the spatial and kinematical distributions of Intermediate Population II stars. At the time, Blaauw was already making regular annual visits to Charlottesville, and discussions were underway to appoint him to a professorship at UVa. Those plans were disrupted when Blaauw became deeply involved in the founding of the European Southern Observatory and subsequently served as its Director General from 1970 to 1975. Needing a collaborator to assist with—and eventually assume leadership of—the project, Blaauw turned to Tolbert, who agreed to help. Blaauw introduced Tolbert to Fredrick at a conference in Hungary, leading initially to a temporary position in Charlottesville. By 1970, the faculty line originally intended for Blaauw was awarded to Tolbert, who continued his radio and stellar collaborations with his mentor.
Although these early research contributions were notable, Charlie’s enduring professional legacy was as a teacher. He soon gravitated toward the classroom and assumed the department’s heavy responsibility for multiple sections of introductory astronomy. In this role he achieved legendary status. Department enrollments flourished as generations of students chose astronomy to fulfill their science general education requirement.
Unmoved by pedagogical fashions, Charlie taught almost entirely at the chalkboard, with the exception of a single “slide show extravaganza” each semester. His personality alone was enough to keep students focused and entertained. Course grades were determined by a fixed set of exams—nothing more and nothing less—with each student permitted to miss or drop one exam, an efficient strategy for managing very large classes. Graduate students eagerly competed for the privilege of serving as his teaching assistants, proudly known as “Tolbert Buddies.”
By the time of his retirement in 2011, Tolbert had taught well over 30,000 students. It is estimated that during his tenure, more than half of all students in the College of Arts and Sciences took at least one astronomy course—an unprecedented figure among U.S. astronomy departments at the time. Statistically, he often emerged as the most popular professor at UVa, with enrollments limited only by the availability and capacity of the largest lecture hall on Grounds. Decades later, UVa alumni still frequently cite Tolbert as one of the professors they remember most vividly. In recognition of his extraordinary impact on astronomy education, Tolbert received the 2014 Richard H. Emmons Award from the Astronomical Society of the Pacific.
Tolbert also served the broader astronomical community in numerous leadership roles. He was Acting Secretary of the American Astronomical Society from 1972 to 1973 and served as AAS Education Officer from 1985 to 1991. In the latter role, he took particular pride in directing the Shapley Visiting Lectureships Program and also served as a Shapley Lecturer himself. He was active in the International Astronomical Union, the American Institute of Physics, and the Royal Netherlands Astronomical Society, and was a Fellow of the American Association for the Advancement of Science. His honors and memberships included the Raven Society at UVa, Phi Beta Kappa, and Sigma Xi.
Along with Larry Fredrick and three other UVa colleagues, Charlie was a founding member of the Society for Scientific Exploration, established by Stanford astrophysicist Peter Sturrock to provide a critical forum—including a peer-reviewed journal—for scientific investigations of unconventional topics. Charlie served the Society as Treasurer for 19 years and as President for seven years. As colleague Robert Rood once observed, Charlie’s interest in the Society may have been driven in part by his fondness for spirited debate. One of his favorite public and college lectures was a thorough—and entertaining—debunking of astrology.
Charlie was deeply engaged in the life of the University of Virginia. He served for eight years as Director of the Office of Academic Space, where he led conservation initiatives during the early 1970s energy crisis and oversaw compliance with the Rehabilitation Act of 1973 and the Americans with Disabilities Act. His commitment to accessibility continued through long service on the Physical Access Committee. He also taught for UVa’s Semester at Sea program, served on the Judicial Review Board and the Faculty Advisory Committee for the Honor System, and from 2003-2009 was Secretary of the General Faculty. Charlie and Carla were also long-time members of the Colonnade (faculty) Club, where he served multiple terms on the Board and two years as President. From 2000 to 2009, he proudly served as Grand Marshal of Final Exercises, leading the University’s graduation ceremonies on Thomas Jefferson’s historic Lawn.
His commitment to public service extended beyond the University. Tolbert served on the Albemarle County School Board for seven years (1982–1989), including two years as Chair; on the Piedmont Regional Education Program for six years (1983–1989), also including two years as Chair; and on the Board of Directors of the Albemarle County Service Authority for twelve years (2014–2025), serving as Vice-Chair during his final three years.
Charlie was known for his wry sense of humor, gentle wit, and ever-present twinkle in his eye. He was beloved by generations of students, postdoctoral researchers, and colleagues who passed through the Astronomy Department. A fitting illustration of his generosity and irreverent warmth is that, though not religious himself, Charlie became an ordained minister of the Universal Life Church so that he could officiate weddings at the request of students and friends.
Laurence "Larry" Fredrick (1927 - 2024)
Dr. Laurence “Larry” W. Fredrick passed peacefully on May 19, 2024 at the age of 96. Larry was instrumental in building the modern-day UVA Astronomy Department, and he was a valued colleague to several generations of astronomers.
After graduating high school, Larry joined the Navy and served in Naval Intelligence from 1945 to 1948. He then attended Swarthmore College and earned his Bachelor’s in Mathematics (1952) and his Master’s in Astronomy (1954). During that time, he visited McCormick Observatory to take observations for his Master’s research. He earned his Ph.D. in Astronomy from the University of Pennsylvania in 1959, and then joined the staff of the Lowell Observatory in Flagstaff, Arizona, where he was involved in the development of photocathode tubes for use in astronomy.
Larry was recruited to the University of Virginia by William Duren, then Dean of the College of Arts & Sciences, who was looking for someone to reestablish the Astronomy Department. At the time, the telescope at McCormick Observatory was not in working order, and much of the equipment was outdated. He came to a department with two faculty members, and through a program of strategic hiring and growth, he led the department to sustained national prominence.
Upon his arrival at UVA in 1963, he served as the last director of the Leander McCormick Observatory and the first chair of the Department of Astronomy. He realized the scientific potential of McCormick Observatory was limited, so he set out to identify a suitable location to build a modern observatory for the University. This led to the establishment of Fan Mountain Observatory in southern Albemarle County, with first a 31-inch general-purpose telescope, followed by a 40-inch astrometric reflector to continue the parallax work of McCormick Observatory. Around this same time, he was supportive of the effort to bring the headquarters for the National Radio Astronomy Observatory to Charlottesville, which invigorated the astronomical research community at UVA.
Larry was known for his broad expertise as an observer. He was an early advocate for the development of space telescopes, which would not be subject to the blurring effects of the Earth’s atmosphere. He later carried out astrometric studies using the Hubble Space Telescope soon after its launch.
In addition to his efforts on behalf of the Department and the University, Larry contributed significant service at the national level. He was Secretary of the American Astronomical Society from 1969-1980, a period of significant change and growth in membership. He was also a member of several other professional societies, such as the Astronomical Society of the Pacific, the Virginia Academy of Science, the Royal Astronomical Society (Fellow), The Planetary Society, and the National Space Society, to name a few. He contributed to the NASA Large Space Telescope Committee, the U. S. Naval Observatory Scientific Visiting Committee, the American Institute of Physics Committee on International Relations, and the American Astronomical Society Committee on Astronomical Public Policy. He chaired NASA’s Astronomy Working Group and was involved in the work of site selection for the Apollo lunar landings. He was also a member of the Astronomy Science Team for the Hubble Space Telescope.
Larry retired from the Department and was honored as a professor emeritus in 1995. Even in retirement, Larry remained an active part of Department life. He frequently lunched with fellow faculty, taking short walks around Grounds to various restaurants. Larry was an avid golfer, and enjoyed golfing locally at Farmington and Birdwood, as well as traveling to golf all over the world. During his time living at Alden House on Mount Jefferson (Observatory Hill), he held annual Halloween parties that are recalled to this day by faculty and graduate students alike. He was also passionate about photography, and enjoyed taking pictures of nature, astronomical events, and his family.
John Hawley (1958 - 2021)
John Hawley, an international award-winning University of Virginia astrophysicist and the senior associate dean for academic affairs for the University’s College and Graduate School of Arts & Sciences, died of cancer on December 12, 2021 at his home in Earlysville. He was 63. He was a member of the department for 34 years. Hawley will be remembered by his colleagues as a brilliant computational astrophysicist who also lent his stature to influential leadership positions within the College as a department chair and associate dean. He came to UVA in 1987 from the California Institute of Technology. Seven years after his arrival on Grounds, Hawley won the Helen B. Warner Prize of the American Astronomical Society, which is awarded to an astronomer under the age of 36 for a significant contribution during the five years preceding the award.
His research focused on the physics of gas accretion. While accretion is ubiquitous in the universe, the physical mechanism that drives it was not well understood. Working with Balbus in the 1990s, however, Hawley identified a powerful instability in magnetized gases that drives the turbulent flow, allowing a detailed understanding of the accretion process. Today, the “magnetorotational instability” is applied to study a wide variety of celestial objects, UVA astronomy chair Phil Arras said, from accretion disks around black holes to the disks from which stars and planets form.
He was an avid cat-lover, which prompted a successful fundraiser benefitting the Charlottesville-Albemarle SPCA. In his memory, the department raised over $1,200.
Mercedes Richards (1955 - 2016)
Mercedes Tharam Richards, 60, of State College, passed away at Hershey, Pennsylvania on February 3, 2016. Richards’s research focused on computational astrophysics, stellar astrophysics, and exoplanets and brown dwarfs. She was most known for her research in the tomography of binary star systems, where her work was considered pioneering in the field. She was elected as an officer for many astronomical organizations, including as president of Commission 42 of the International Astronomical Union, as a councilor of the American Astronomical Society, and as a member of the Board of Advisers of the Caribbean Institute of Astronomy.
She joined the faculty at UVA in 1987. She was appointed as assistant professor of astronomy in 1987, promoted to associate professor in 1993, and to professor of astronomy in 1999. In addition, she was a visiting scientist during the 2000-2001 academic year at the Institute for Advanced Study in Princeton, New Jersey. In 2002, she joined the faculty of Penn State as a professor of astronomy and astrophysics.
Robert "Bob" Rood (1942 - 2011)
Bob Rood, professor emeritus of astronomy in the University of Virginia's College of Arts & Sciences, died Nov. 2 after suffering a stroke while at John F. Kennedy Airport in New York. He had been en route to Italy to collaborate with colleagues. After studying at North Carolina State University, he earned his Ph.D. in astrophysics from the Massachusetts Institute of Technology in 1969 and conducted postdoctoral research at the California Institute of Technology. He also collaborated with colleagues worldwide, particularly in Bologna, Italy, Green Bank, W.Va., and Bonn, Germany. He started his career as a stellar structure and evolution theorist, later focusing on observational studies of star clusters and interstellar gas in the Milky Way.
Bob was an integral and active part of the University of Virginia community. Since 1973, he enjoyed his work as a professor in University of Virginia's astronomy department, serving as department chair from 1999 until 2006. He taught a popular course called "Life Beyond Earth" and co-authored a book on extraterrestrial life. Bob's research spanned both theoretical studies of how stars evolve over time and observational studies of star clusters and interstellar gas in the Milky Way, as well as studying the abundances of elements cooked up during the Big Bang fireball that created our universe.
Bob was an avid photographer, and captured hundreds of images of UVA Astronomy faces during his 38 years in the department. In his honor, the Department's Graduate Research Symposium is now known as the Bob Rood Symposium. This is a day-long event featuring current graduate student research talks and a reception at McCormick Observatory.
