Rosalie Frances Maddocks

Rosalie Frances Maddocks was born on August 27, 1938, in Lewiston, Maine. She attended the University of Maine, originally majoring in French. An elective course in geology changed her entire life; she received a Bachelor of Arts in Geology in 1959. She then moved to Lawrence, Kansas where she received a Master’s Degree in Geology in 1962 and then a Ph.D. in Geology in 1965 from the University of Kansas.

From 1965 to 1967 Rosalie performed postdoctoral research as an assistant curator for Richard H. Benson at the Smithsonian Institution studying ostracods of the International Indian Ocean Expedition.

Rosalie joined the faculty of the University of Houston in 1967 as a Professor in the Department of Earth and Atmospheric Sciences and remained a guiding presence for generations of students and colleagues. Her career spans nearly six decades of teaching, research, and scholarly leadership in the field of micropaleontology, with particular emphasis on the biology, taxonomy, ecology, and evolutionary history of ostracods – microscopic crustaceans widely used as indicators of environmental and paleoceanographic change.

Rosalie was internationally recognized for her expertise in ostracod taxonomy and systematics, marine micropaleontology, paleobiology, and paleoecology. Much of her research focused on living and fossil marine microfauna of the Gulf of Mexico, where her work helped scientists better understand ancient and modern environmental conditions. She published extensively, contributing foundational research that continues to inform studies in marine geology and paleoenvironmental reconstruction. Her involvement in the University of Houston’s Applied Sequence and Biostratigraphy Program further strengthened the bridge between academic scholarship and applied geoscience.

She had a deep and enduring love of literature and reading, and a curiosity about the world that extended far beyond science. Books, ideas, and the pursuit of knowledge were constants in her life. She believed deeply that learning was a lifelong endeavor, and that the scientific method was not merely a professional tool, but a way of thinking – one that could guide both careers and everyday life. She brought that philosophy into everything she did.

Even in the face of serious illness, Rosalie’s commitment never wavered. Despite her battle with cancer and the toll of treatment, she continued to teach and work for as long as she possibly could, remaining devoted to her students and her field until her recent hospitalization.

She died peacefully on April 15, 2026 in Houston, Texas. She was preceded in death by her parents, Harold E. and Marian L. (Mitchell) Maddocks. She is survived by her two sisters, Eileen Maddocks and Geraldine Whitfield, and by her two brothers, Harold and Alex Maddocks.

A memorial service will be held at the University of Houston at a later date.
