Today's subject is the brilliant scientist, William Webster Hansen. A member of Clan William he descends in this way:

William Webster Hansen was born to William George Hansen, son of a Danish immigrant, and hardware sales manager and his wife, Laura Gillogly, daughter of Rev James Lee Gillogly and wife Lydia Lucelia Webster on 27 May 1909 in Fresno, California. William had one sibling; a brother, James L Hansen (1917-1993).

In 1942, he was appointed to a full professorship at Stanford. World War II was raging and the physics team was working full-throttle for the war effort.
Describing the work he did theyears from 1943-1949, the following is currently posted on the Stanford website and shows that his work was of critical importance:
The Middle 1930's through the 1960's
Encouraged initially by Enrico Fermi to do experimental physics because, among other things, it was "fun," in 1938 Bloch (in collaboration with Luis Alvarez) made the first experimental measurement of the magnetic moment of the neutron, marking the beginning of the work for which he is perhaps best known.
By the end of the Second World War, Bloch, working with Bill Hansen and Martin Packard, had succeeded in observing nuclear magnetic resonance (NMR) in condensed matter by the method of nuclear induction. For these discoveries, and the discoveries made with this technique, Bloch shared the 1952 Nobel Prize in Physics with Harvard's Edward Purcell.
It was Stanford's first Nobel Prize. NMR has since become the most important spectroscopic technique in chemistry and biology, and magnetic resonance imaging (MRI), an imaging technique based upon it, is considered the greatest advance in medical imaging since the discovery of X-rays in 1895.
In the late 1930s, Research Associates Russell and Sigurd Varian, working in collaboration with their mentor, Professor Bill Hansen, invented the klystron, a high-power microwave source and amplifier. The klystron was rapidly developed during World War II for use in radar, navigation, and blind-landing devices for aircraft.
But Hansen, whose own contribution to the klystron was the resonant cavity called a rhumbatron, was interested in using the klystron for the acceleration of particles. And by 1947 he had built the first linear electron accelerator, the Mark I, which accelerated electrons to 6 MeV.
Then, just four years later, Edward Ginzton and Marvin Chodorow completed the Mark III, a 1-GeV electron accelerator. It was the Mark III that allowed Robert Hofstadter to study the charge and magnetic structure of nuclei and nucleons, work that earned him the 1961 Nobel Prize in Physics.
Stanford Linear Accelerator Center
Hansen's work has continued to be highly fruitful. In 1967, the Stanford Linear Accelerator Center (SLAC), a national facility designed to hold a new two-mile accelerator, was completed and running, and nine years later, Stanford's Burton Richter shared the Nobel Prize for the discovery of the Psi/J-particle. In 1988, Mel Schwartz, a long-time member of the department, shared the Nobel Prize for his discovery of the muon neutrino, though this work had been done earlier at Brookhaven. Then, in 1990, Dick Taylor shared the Nobel Prize for his studies of deep inelastic scattering, which showed the existence of point-like objects in nucleons, now recognized as quarks. In 1995, Martin Perl won the Nobel Prize in Physics for his discovery of a new elementary particle known as the tau lepton. https://physics.stanford.edu/our-history
On 10 Aug 1947, the Hansen's welcomed their only child, Peter Ross Hansen. Fate would not be kind as the infant died on 28 Sep 1947.
Just two years later, on 23 May 1949, Dr. Bill Hansen died at the age of 39. He died of a lung condition and pneumonia. Colleagues attributed his illness to overwork.
