Frederick Soddy was a British radiochemist who won the Nobel Prize in Chemistry in 1921. Educated at Merton College Oxford, he started his career at McGill University in Montreal and with Ernest Rutherford established the ‘Theory of Atomic Disintegration’. Later he joined Sir William Ramsay at University College London and together they demonstrated that radioactive disintegration of radium bromide produces helium. During his long career, he also proposed ‘Displacement Theory’ and discovered protactinium. However, formulation of the concept of isotopes was his most significant work. Much later, he received the Nobel Prize in Chemistry for it. Interestingly, towards the end of his life he lost interest in chemistry and began to write on economic, social and political problems. He not only campaigned for total restructuring of global monetary system, but was also angry that the world’s economic system failed to take the advantage of scientific advancemnent. However, his theories in these regards remained unacceptable at least during his lifetime. He was said to be a man of strong principles. Many found his views to be rather obstinate and his nature prickly. However, he was quite friendly to his students and was very popular among them.
