Frederick Soddy is awarded the 1921 Nobel Prize in Chemistry for his contributions to our knowledge of the chemistry of radioactive substances, and his investigations into the origin and nature of isotopes.

Frederick Soddy works for the next two years at the University of Oxford.

Frederick Soddy, together with Sir Ernest Rutherford, investigates the gaseous emanation of radium.

Frederick Soddy, together with Sir William Ramsay, demonstrates that in the radioactive decay of radium produces helium.

Frederick Soddy visits Eastbourne College at Eastbourne.

First entering the University College of Wales at Aberystwyth Frederick Soddy gets a scholarship at Merton College, Oxford University in 1895. He gains his Bachelor's degree in Chemistry in 1898.

From 1914 to 1919 Frederick Soddy is Professor for Chemistry at the University of Aberdeen. Since this time he stops his work on radioactivity and switches more and more into economic, social and political theories.

Frederick Soddy is born to his father Benjamin, a corn merchant, and his mother Hannah Green Soddy in Eastbourne, England. He is the youngest of four sons.

Frederick Soddy is appointed Dr. Lees Professor of Chemistry at the University o Oxford in 1919. He holds this position until his retirement in 1937, which is caused by the death of his wife in 1936.

Frederick Soddy leaves Canada to continue the study of radium emanation at the University College, London.

Frederick Soddy moves to Canada in 1900 and becomes a Demonstrator at the Chemistry Department of McGill University in Montreal. There he and Sir Ernest Rutherford are conducting research on radioactivity.

Frederick Soddy and Winifred Moller Beilby get married on 27. March of 1908.

Frederick Soddy works as Lecturer in physical chemistry and radioactivity at the University of Glasgow from 1904 to 1914, where he does much practical chemical work on radioactive materials.

Frederick Soddy dies on 22. September of 1956 in Brighton, England.

In 1913 Frederick Soddy shows that on alpha emission the element moves back two places in the Periodic Table. That the so-called radioactive displacement law of Fajans and Soddy. Furthermore Soddy demonstrates that atoms of radioactive elements can have different masses, but may have the same chemical properties. He names this concept isotopes.
