Kenneth Sanborn Pitzer (January 6, 1914 – December 26, 1997) was an American physical and theoretical chemist, educator, and university president. He was described as "one of the most influential physical chemists of his era" whose work "spanned almost all of the important fields of physical chemistry: thermodynamics, statistical mechanics, molecular structure, quantum mechanics, spectroscopy, chemical bonding, relativistic chemical effects, properties of concentrated aqueous salt solutions, kinetics, and conformational analysis."
He received his B.S. in 1935 from the California Institute of Technology and his Ph.D. from the University of California, Berkeley in 1937. Upon graduation, he was appointed to the faculty of UC Berkeley's Chemistry Department and was eventually elevated to professor. From 1951 to 1960, he served as dean of the College of Chemistry.
He was the third president of Rice University from 1961 until 1968 and sixth president of Stanford University from 1969 until 1971. His tenure at Stanford was turbulent due to student protests. Worn out by the confrontations, he announced his resignation in 1970 after a 19-month tenure. He returned to UC Berkeley in 1971. He retired in 1984, but continued research until his death.
He was Director of Research for the U.S. Atomic Energy Commission from 1949 to 1951 and a member of the National Academy of Sciences.
As a scientist he was known for his work on the thermodynamic properties of molecules. While still a graduate student he discovered that hydrocarbon molecules do not rotate unhindered around their C-C bonds. There is in fact a barrier to internal rotation, an important discovery upsetting the conventional wisdom and affecting the thermodynamic properties of hydrocarbons. Some of his work is summed up in the Pitzer equations describing the behavior of ions dissolved in water. During his long career he won many awards, most notably the National Medal of Science and the Priestley Medal.
