Mitchell Jay Feigenbaum, a theoretical physicist whose inquiring mind and intense focus enabled him to contribute broadly across many fields, died of a heart attack on 30 June 2019 in New York City. Mitchell’s most celebrated work was his discovery of the universality of the period-doubling transition to chaos and the associated Feigenbaum constant, δ = 4.6692016 …. His predictions were confirmed experimentally in Albert Libchaber’s convection experiments in 1979. For their work, the two men shared the 1986 Wolf Prize in Physics.
