biochemist Severo Ochoa (1905-1993) travelled throughout Europe in the late 1930s after
the Spanish Civil War began. He worked at the Kaiser Wilhelm Medical Research Institute in
Berlin, Germany, and also stopped in England before travelling across the Atlantic to the
United States. He was awarded the Nobel Prize in Physiology or Medicine in 1959
alongside Arthur Kromberg for their work on the synthesis of RNA and DNA. He
received the Nobel Prize while employed by the New York University School of Medicine.
Ochoa continued his work on RNA and protein synthesis for decades afterwards, returning to
