Albert Bruce Sabin (1906-93) Signed Photo, "To Tina Marelli - best wishes - Albert B. Sabin", 5 x 7, b/w, by the Polish American medical researcher, best known for developing the oral polio vaccine, which has played a key role in nearly eradicating the disease. The Sabin vaccine is easier to give than the earlier vaccine developed by Salk in 1954. Sabin refused to patent his vaccine, waiving every commercial exploitation by pharmaceutical industries, so that the low price would guarantee a more extensive spread of the treatment. From the development of his vaccine Sabin did not gain a single dollar, and continued to live on his salary as a professor. From 1970 until 1972, Dr. Sabin served as President of the Weizmann Institute of Science in Rehovot, Israel. It is a public research university in Rehovot, Israel, established in 1934, 14 years before the State of Israel. It differs from other Israeli universities in that it offers only graduate and postgraduate degrees in the natural and exact sciences. Comes with the original mailing envelope with the "Weizmann Institute of Science" return address and has several Israeli postmarks dated April 19, 1971. Both items in fine condition, with small paperclip impression on left edge of the photo and opening tear and creases to the envelope.
