Robert E. Connick (July 29, 1917 – August 21, 2014) was a professor emeritus of chemistry at the University of California, Berkeley.

He was a research associate on the Manhattan Project from 1943 - 1946, and has been a professor, chair of the chemistry department, dean of the college of chemistry, vice chancellor,[2] and chair of the academic senate at both Berkeley and the entire University of California system.

He is most known for development of nuclear magnetic resonance methods for determining rates of water exchange reactions.

Connick’s studies revealed plutonium’s complicated oxidation-reduction properties and the existence of many ions.

The results showed scientific basis for the various practical separation processes developed during and since World War II.
