Kenneth Marshall Watson (September 7, 1921 – August 18, 2023) was an American theoretical physicist and physical oceanographer.
[5] He graduated from the University of Iowa with Ph.D. in 1948 with thesis The polarizability of the meson-charge cloud of a neutron in an external electrostatic field.
In 1959 he worked with Marvin L. Goldberger, Keith Brueckner, and Murray Gell-Mann to join John A. Wheeler, Charles H. Townes, and others in forming the JASON group of government advisors.
To quote Watson: In the mid-1960s I began a series of investigations, in collaboration with M. L. Goldberger of the observation of “entangled” quantum mechanical systems.
[5]Watson did research in the early 1970s on atomic and molecular scattering and in the late 1970s on fluid mechanics related to oceanography.
The Hamiltonian formulation of this is mathematically very similar to the equations of classical and quantum mechanical field theory that I had encountered at the beginning of my career.
