PHILIP ANDERSON, a Nobel laureate and professor emeritus of physics, died March 29 in Princeton. He was 96. Anderson joined the faculty in 1975 and transferred to emeritus status in 1996. His research on the electronic structure of magnetic and disordered systems influenced the development of electronic switching and memory devices in computers. Anderson shared the Nobel Prize in Physics in 1977 and received the National Medal of Science in 1982. Parts of his research are incorporated in the Standard Model of particle physics.

JOHN HORTON CONWAY, a professor known for his love of mathematical games and his ability to delve into a variety of theoretical topics, died April 11 in New Brunswick, New Jersey, from complications related to COVID-19. He was 82. Conway, who served on the mathematics faculty for 26 years, contributed significant research in fields ranging from theoretical physics to geometry. With Princeton colleague Simon Kochen, he developed a free-will theorem, published in Foundations of Physics in 2006. Conway’s “Game of Life,” a computer simulation that does not require input from the players, gained a cult following in the early 1970s.
