Dr Frieda Robscheit-Robbins
The 1934 Nobel Prize in Physiology or Medicine was awarded to three men—George Whipple, George Richards Minot, and William P. Murphy—for their research into the use of liver tissue in treatment of pernicious anaemia. Frieda Robscheit-Robbins, who had co-authored twenty-one papers with Whipple (almost his entire body of published work) on the topic, was left out.
