RIP Tony Leggett

Prof. Leggett was a soft-spoken, kind person who was also a brilliant theoretical physicist. I was fortunate enough to first meet him back when I was a graduate student working in Doug Osheroff's lab. Doug had discovered (along with his thesis advisors Bob Richardson and Dave Lee) the superfluid phases of the rare isotope of helium, 3He in 1972. [Science digression: 3He atoms are fermions - if you add up the spin angular momentum from the two protons, the neutron, and the two electrons, you end.
