Leonard Herzenberg was in his lab at Stanford University one day in the early 1960s, laboriously counting cells under a microscope. His eyes hurt. “There’s got to be some kind of machine that can do this,” he remembered muttering.
He went on to develop precisely that — and in doing so helped revolutionize immunology, facilitate stem cell research and advance the treatment of cancer, H.I.V. infection and other illnesses.
Dr. Herzenberg, who died on Oct. 27 at 81 in Stanford, Calif., created a device that can pick out individual cells from a mass of trillions of them and then capture, sort and count them so they can be analyzed and used to fight disease.
