Neil Bartlett, an emeritus professor of chemistry whose groundbreaking experiments challenged the prevailing views of the nature of noble gases, died unexpectedly on Tuesday, Aug. 5, at John Muir Medical Center in Walnut Creek from an aortic aneurysm. He was 75.

Bartlett was best-known for his 1962 experiment, at the University of British Columbia (UBC), demon-strating that xenon, a member of the family of noble gases, could form compounds.

Until Bartlett’s experiment, chem--istry students had been taught that the noble gases, including helium and neon, were inert and unable to form chemical bonds with other elements. The nature of chemical bonds, and how they join elements together to form compounds, is one of the most fundamental concepts in chemistry. Bartlett’s work, which was critical to the modern understanding of the chemical bond, led to noble-gas compounds that are used in the creation of antitumor agents and in specialized lasers.

The news that Bartlett had formed a compound of xenon shocked the scientific world; it was hailed in 2003 by Chemical & Engineering News as one of the “10 most beautiful experiments in the history of chemistry.”

“Bartlett was the first person to prepare a compound of a so-called ‘inert’ or ‘noble’ gas,” said William Jolly, professor emeritus of chemistry and a colleague of Bartlett’s. “For that action he deserved a Nobel Prize, although it was never awarded to him. He will forever be recognized as a genius by the scientific community for the logical and imaginative procedure he used in that preparation.”

In 2006 the American Chemical Society, in conjunction with the Canadian Society of Chemistry, designated a new International Historic Chemical Landmark to honor the work of Bartlett. The landmark at UBC in Vancouver commemorates Bartlett’s famous 1962 experiment and includes a plaque that says, “Spurred by Bartlett’s success, other scientists soon began to make new compounds from xenon, radon, and krypton. With Bartlett’s simple experiment, the old ‘law’ of the unreactivity of the noble gases had disappeared.”

Bartlett was born Sept. 15, 1932, in Newcastle upon Tyne, England. At an early age he became interested in chemistry, building his own lab at home. Bartlett once recalled conducting an experiment at age 12 in which he prepared what he called “beautiful, well-formed” crystals by the reaction of aqueous ammonia and copper sulfate.

His knowledge of chemistry earned him a scholarship to attend King’s College in Durham, England, where he earned his B.S. in 1954 and his doctorate in 1958. That same year, Bartlett was appointed a lecturer in chemistry at UBC, where he remained until 1966, eventually reaching the rank of full professor. It was during his time there that he conducted his most famous experiment.

After a three-year stay at Princeton University, where he discovered he missed the West Coast, Bartlett joined the chemistry faculty at Berkeley in 1969. He retired in 1993 but continued to work as a senior scientist at the Lawrence Berkeley National Laboratory until 1999. Bartlett became a U.S. citizen in 2000.

In addition to his research with noble gases, Bartlett’s studies included the general field of fluorine chemistry, with a special interest in the stabilization of unusually high oxidation states of various elements.

Bartlett is also known for his contributions to the understanding of the thermodynamic, structural, and bonding properties of chemical reactions. He helped develop novel synthetic approaches, discovered and characterized many new fluorine compounds, and also produced many new metallic graphite compounds, including some that show promise as battery materials.

Bartlett won numerous national and international awards, including the Welch Award in chemistry; the Prix Henri Moissan from France, where he was a foreign associate of the Institut de France (Académie des Sciences); and the Davy Medal of the Royal Society of London, where he was elected a fellow. He was a member of both the American Academy of Arts and Sciences and the National Academy of Sciences, and received many honorary degrees from universities around the world.

In his retirement, Bartlett enjoyed watercolor painting, carpentry, silversmithing, and gardening. At the time of his death he was living in Orinda with his wife of 51 years, Christina Bartlett. He is also survived by his sons, Jeremy Bartlett of El Cerrito, Christopher Bartlett of Palo Alto, and Robin Bartlett of Oakland; and by his daughter, Jane Piggott of Folsom. He also leaves five grandchildren.
