About the author

Robert Laurence Mills (April 15, 1927 – October 27, 1999) was a physicist, specializing in quantum field theory, the theory of alloys, and many-body theory. While sharing an office at Brookhaven National Laboratory, in 1954, Chen Ning Yang and Mills proposed a tensor equation for what are now called Yang–Mills fields. This equation reduces to Maxwell's equations as a special case.
