studying in the Cavendish, Ernest Rutherford became
fascinated by radioactivity. He investigated it for
twenty years, first at McGill University, Canada and
then at the University of Manchester, before returning
in 1919 to lead the Cavendish as its Professor.
most famous discovery took place while he was Professor
at Manchester. In March 1911 Rutherford announced that
each atom contains a positively charged nucleus. Investigations
of these nuclei became known as 'nuclear physics'. Rutherford's
discovery ultimately led to the 'splitting of the atom',
more than twenty years later in the Cavendish.
