Leonard Herzenberg (1931-2013)

Leonard Herzenberg died on October 27, 2013 aged 81. He had been hospitalized since he suffered a severe stroke on October 8. In cooperation with his wife and scientific partner, Lee Herzenberg, he brought the power of flow cytometry to the field of immunology, and developed fluorescence activated cell sorting, the basis to purify stem cells today. Without the Herzenbergs, tens of thousands of people now alive would not be. I'm glad I had the privilege to meet him and his wife. I will never forget you, Len.
