George Washington University while in Washington, D.C. Emmett joined Johns Hopkins University in 1937 to establish the Department of Chemical and Gas Engineering alongside Ralph Witt, Charles Bonilla, and Lloyd Logan. He was the chair of the department from 1937 to 1943. During this period, Emmett published his famous work on the Brunauer-Emmett-Teller (BET) Theory, which later earned him a Nobel Prize in Chemistry nomination in 1967. In 1943, Emmett left Johns Hopkins University to become a division chief on the Manhattan Project at Columbia University under the directive of Harold Urey. For 16 months, Emmett's lab focused on separating uranium isotopes and converting uranium into a corrosive gas. Emmett remained on the Manhattan Project as a consultant for the Oak Ridge National Laboratory for 22 years. In 1944, he relocated to the Mellon Institute of Industrial Research in Pittsburgh, PA to conduct petroleum research. In 1955, Emmett moved back to Johns Hopkins University, albeit in a different department, as the William R. Grace Professor of Chemistry. He was active both nationally and internationally with various chemistry committees and conferences. He was elected to National Academy of Sciences in 1955. Emmett finished his career at Johns Hopkins University, retiring in 1971 with the Professor Emeritus distinction. For the remainder of his life, Emmett was a visiting research professor at Portland State University, undertaking new research areas, giving seminar talks, and teaching advanced courses in catalysis. Personal life Emmett was a close friend and classmate of Linus Pauling with whom he attended high school, college, and graduate school. Emmett was married to Leila Jones on July 14, 1930, until her death in 1968. He had a short second marriage which ended in divorce. Pauling became brother-in-law to Emmett after he married Pauling's older sister, Pauline, in 1976. She survived him, eventually passing away in 2003 at the age of 101. Death and legacy Emmett suffered from Parkinson's disease and a brain tumor during the later stages of his life. He died on April 22, 1985, at the age of 84. In total, Emmett authored 164 publications, some of which are still cited to this day. The Paul Hugh Emmett award was established in 1972 by the Catalysis Society of North America. Research Doctoral work and thesis Emmett's doctoral advisor, Arthur F. Benton, had studied under Hugh Stott Taylor at Princeton University. Emmett worked with Benton to study the role of nickel
