Chase (September 17, 1905 \u2013 January 5, 2004) was an immunologist working at the Rockefeller University in New York City who is credited with discovering cell-mediated immunology in the early 1940s. While working with Dr. Karl Landsteiner, Dr. Chase discovered that white blood cells, and not antibodies alone, were important instruments of the immune system."@en . "Chase, Merrill"@en . . .
