Ernest T.S. Walton
Biography
Ernest Thomas Sinton Walton was born at Dungarvan, County Waterford
on the south coast of Ireland on October 6th, 1903, the son of a Methodist
Minister from County Tipperary. The ministry demanded that his father
move from place to place every few years, and he attended day schools
in Banbridge (County Down) and Cookstown (County Tyrone). In 1915 he was
sent as a boarder to the Methodist College, Belfast, where he excelled
in mathematics and science, and in 1922 he entered Trinity College, Dublin
, on a scholarship. He read the honours courses in both mathematics and
experimental science, specializing in physics, and graduated in 1926 with
firstclass honours in both subjects; he received his M.Sc. degree in 1927.
In 1927, he was awarded a Research Scholarship by the Royal Commissioners
for the Exhibition of 1851 and he went to Cambridge University to work
in the Cavendish Laboratory under Lord Rutherford. He continued at Cambridge
after receiving a senior research award of the Department of Scientific
and Industrial Research in 1930, and received his Ph.D. in 1931. Walton
was Clerk Maxwell Scholar from 1932 to 1934 when he returned to Trinity
College, Dublin, as Fellow: he was appointed Erasmus Smith's Professor
of Natural and Experimental Philosophy in 1946, and in 1960 he was elected
Senior Fellow of Trinity College.
Prof. Walton's first researches involved theoretical and
experimental studies in hydrodynamics and, at the Cavendish
Laboratory, he worked on indirect methods for producing fast
particles, working on the linear accelerator and on what was
later to become known as the betatron. He followed this with work
on the direct method of producing fast particles by the use of
high voltages this work being done jointly with J.D. Cokcroft. A
suitable apparatus was built which made it possible to show that
various light elements could be disintegrated by bombardment with
fast protons. They were directly responsible for disintegrating
the nucleus of the lithium atom by bombardment with accelerated
protons, and for identifying the products as helium nuclei.
Prof. Walton has taken part in many activities outside his
academic work, and he has served on committees connected with the
Dublin Institute for Advanced Studies, the Institute for
Industrial Research and Standards, the Royal City of Dublin
Hospital, the Royal Irish Academy, the Royal Dublin Society,
Wesley College, Dublin, and many government and church
committees. He has had numerous scientific papers published in
the journals of learned societies, particularly on the subjects
of hydrodynamics, nuclear physics, and microwaves.
He was awarded the Hughes Medal, jointly with Sir John Cockcroft,
by the Royal Society of London in 1938, and in 1959 he received
an honorary Doctor of Science degree from Queen's University,
Belfast.
E.T.S. Walton married Freda Wilson, daughter of a Methodist
Minister and a former pupil of Methodist College, Belfast, in
1934. They have two sons and two daughters, Alan, Marian, Philip,
and Jean.
