Ada Florence Remfry Hitchins (26 June 1891 – 4 January 1972) was the principal research assistant of British chemist Frederick Soddy, who won the Nobel prize in 1921 for work on radioactive elements and the theory of isotopes.[1][2][3] Hitchins isolated samples from uranium ores, taking precise and accurate measurements of atomic mass that provided the first experimental evidence for the existence of different isotopes.[4] She also helped to discover the element protactinium,[4] which Dmitri Mendeleev had predicted should occur in the periodic table between uranium and thorium.[5]
