One of twelve slides from Frederick Chapman Robbins (1916-2003), a physician who received the 1954 Nobel Prize in Physiology or Medicine. The slides, which date from c. 1948, relate to the work that Dr. Robbins and his colleagues did with the polio virus. They were the first to successfully grow the virus in tissue culture.
