Retrospective: Quentin H. Gibson (1918 – 2011)

During his early years at Cornell, Gibson and Richard DeSa automated the collection of data from all his rapid kinetic instruments, using minicomputers to provide the first millisecond digital readouts of kinetic data in enzymology. This technology was applied to a complete analysis of O2 binding. Both equilibrium curve and time course data were analyzed by combined analog and digital computing. Next, Gibson turned his attention to the problems associated with naturally occurring hemoglobinopathies, the properties of globins from a variety of plant and animal species, the differences between the alpha and beta subunits of human hemoglobin, and the rate of the R to T quaternary transition.

After developing a stomach ulcer in 1969, Gibson decided to spend his summers at Woods Hole, which he did from 1970 to approximately 1990. He and his wife Jane bought a house there and a sailboat, which he used every summer until Hurricane Gloria destroyed it in 1985. Jane taught in the summer microbiology course at the Marine Biological Laboratory, and Quentin went out on expeditions to collect fish blood with Frank Carey. After he returned to Cornell in the fall, his students studied ligand binding to fish Hbs, which showed unusual pH and temperature effects (6).

In the 1980s, Gibson’s group constructed laser photolysis systems to examine internal (geminate) rebinding within the globin molecules at room temperature. These experiments then were used to determine pathways for ligand movement into and out of the protein matrix using site-directed mutagenesis in collaboration with a variety of laboratories. In the 1990s, Ron Elber helped Gibson implement the use of molecular dynamics simulations for interpreting the ultrafast picosecond and nanosecond recombination processes that were being measured in his laboratory with both native and mutant proteins.

In 1996, Gibson and his wife retired from Cornell University and moved permanently to Etna, N.H. They spent the winter months of 1996 to 2001 in Houston, Texas. There, Quentin worked in a kinetics laboratory set up for him at Rice University, continuing his collaborative studies with John Olson and George Phillips, while Jane worked in the microbiology department at the University of Texas Medical School Houston. This time period was highly productive and led to a detailed map of the pathway for O2 migration into and out of Mb. In 2002, Gibson decided to stay year-round in New Hampshire, but a small kinetics laboratory in William Royer’s laboratory at the University of Massachusetts Medical School allowed him to keep doing experiments on hemoglobins until 2009, the year his last research article appeared in print. Even after he was unable to make the trip to Worcester, Gibson continued to advise the Royer lab on both experimental techniques and interpretations of kinetic data well into the last year of his life. 

Gibson’s career truly was remarkable. He published papers from 1943 to 2009, a span of almost seven decades. When he began his studies of hemoglobin in the 1940s, its structure was completely unknown, but when he ended his career, his papers described detailed movements of diatomic oxygen through a gate opened by rotation of the distal histidine and then its capture in well-specified cavities in the protein that were engineered by recombinant DNA technology, visualized by time-resolved X-ray crystallography, and analyzed by molecular dynamics simulations. In 2004, he wrote a detailed and amusing history of these changes in our understanding of hemoglobin kinetics (7).

A few months before his death, the regents of the University of Sheffield recognized Gibson’s contributions to science and to the reputation of their institution by granting him an honorary Doctorate of Science and establishing an eponymous lectureship. In January of 2011, he reflected peacefully and with contentment that this honor had brought his academic career full circle.

I had the opportunity of working with Quentin for some months in 1990-1991, and greatly appreciated his profound insight and his patience and clarity in discussing and explaining the details of the experiments we were carrying out. I always felt greatly enriched by my experience at Cornell, and deeply indebted with him. Andrea Bellelli, Rome, Italy.


Not only was Quentin a remarkable and brilliant scientist, but he was also a kind and generous person, always ready to discuss science (yours and his) with insight and enthusiasm. He will be missed. Gordon Tollin, University of Arizona


I first met Quentin when we were both at the University of Sheffield in the 50's (I was in the chemistry department). Our group was studying nickel complexes, but the beautiful spectral changes were too fast to study by the usual method. Quentin introduced me to his stopped flow apparatus and we had instant success in measuring the kinetics of reactions of a large number of complexes for the first time, thanks to his kindness and considable help.In the U.S.for nearly 40 years our group studied a large number of inorganic and bioinorganic reactions using the Gibson-Dionex commercial apparatus.Our computerised set up was built by Dick DeSa who studied with Quentin.It is obvious then how indebted I am to Quentin Gibson so many years ago. Ralph G. Wilkins, Albuquerque, NM, USA.


In addition to his extensive research career, Quentin Gibson was a great mentor, generous with both his time and knowledge. From working with him at Rice University, I can attest to not only his scientific acumen, but his willingness to share what he knew and his excitement for heme proteins with multiple generations of students. He is greatly missed.
