 | John P. Trinkaus |
John P. Trinkaus, professor emeritus and senior research scientist in molecular, cellular and developmental biology, died on Feb. 8 at age 84.
Author of the classic book "Cells into Organs: The Forces that Shape the Embryo," Professor Trinkaus has been described by the National Cancer Institute as the world's leading expert on in vivo cell movements. He provided readers with critical analyses of cell motility and the ability of cancerous and normal cells to invade other tissue. It was the only book in the field at that time that focused on the migration of tissues and cells and studied how they formed complex organs during development.
Professor Trinkaus spent many years performing his research at Marine Biological Laboratory, Woods Hole, Massachusetts and the Station Marine, Roscoff, Brittany, France with many of his collaborators, postdoctoral fellows and students. Using sea urchin and fish eggs, he used time-lapse videography to capture the movements of individual cells on the surface and in the interior of the egg. Professor Trinkaus investigated the mechanisms and external factors responsible for the migration of embryonic cells, from the sites of their origin to their ultimate destinations in the developing organism. His autobiography, "The Embryologist," which will soon be released, describes many of these scientific exploits.
In 1987, Professor Trinkaus was among the first group of American scientists to receive a MERIT Award from the National Institutes of Health. This grant allowed him to continue his research after his retirement from Yale.
He received his bachelor's degree with honors and high distinction in biology from Wesleyan University, his master's from Columbia University and his doctorate from Johns Hopkins University in 1948. He joined the Yale faculty that year and spent his entire academic career in the Department of Zoology and its successor, the Department of Biology. Professor Trinkaus was also director of graduate studies in biology and served as master of Branford College 1966-1973. During his tenure at Yale, he was recognized as a superior teacher, and his courses were always among the most popular in his department. He attracted many outstanding graduate students to his laboratory, and many of these students now hold appointments at leading universities.
Professor Trinkaus was chair of the Gordon Research Conference on Cell Contact and Movement in 1979, summer investigator at the Marine Biological Laboratory in Woods Hole for many years and a member of the space biology advisory panel of NASA 1976-1979. He also wrote "On the Mechanism of Metazoan Cell Movements" in 1976, and authored many professional journal articles.
A John Simon Guggenheim fellow at the ,College de France, Paris 1959-1960, Professor Trinkaus was also a member of the American Society of Zoologists, the American Society for Cell Biology, the American Society for Developmental Biology and the International Institute of Embryology.
Professor Trinkaus is survived by his wife of 40 years, Madeleine Bazin Trinkaus of Guilford, Connecticut; his children, Gregor Trinkaus-Randall of Stow, Massachusetts; Tanya Trinkaus Glass of North Kingstown, Rhode Island; and Erik Trinkaus of Ladue, Missouri. He also leaves five grandchildren: Jennifer and Christopher Trinkaus-Randall, Trina Nix, Alex Shore and Sasha Trinkaus; and one great-grandson, Connor Nix.
