Soddy, Frederick (1877–1956)
British chemist and physicist who was awarded the 1921 Nobel Prize in Chemistry
for his theory of isotopes, a term he coined.
Soddy carried out research on radioactivity
with Ernest Rutherford, and later
William Ramsay. In 1920 he produced an explanation
of the radioactive decay of isotopes that proved invaluable in calculating
geological time. Soddy and Ramsay found helium
to be a product of uranium. His classic
science books include The Interpretation of Radium (1909), Matter
and Energy (1912), and The Chemistry of the Radio-Elements
(1911–14).
