César Milstein was born on this day in 1927 in Bahia Blanca, Argentina. He joined LMB in 1963 and worked here until his death in March 2002. On day 281 of #LMB365 he is seen receiving his Nobel Prize Medal for Physiology and Medicine for his development of the technique to produce monoclonal antibodies. On the announcement of the award César commented “we were stuck for a few months, and getting negative results. It is the struggle of that period and all the scientific tension that I remember the most. It was little bits of excitement rather than one moment.” Photo courtesy of Celia Milstein
