Who is John Cockcroft?

undefined - John CockcroftJohn Cockcroft

John Cockcroft was a British Physicist who shared the 1951 Nobel Prize in Physics with Ernest Walton for their work on splitting the atomic nucleus. Born in a family of cotton mill owners, he was a good student and chose to pursue scientific research. After having completed his school education, he started studying mathematics in Manchester University but he had to cut it short in order to contribute towards the war effort during the First World War. After the end of the war, he resumed his studies and studied electrical engineering at the College of Technology under Miles Walker. Thereafter, he took the Mathematical Tripos and then worked under Lord Rutherford in the Cavendish Laboratory. During his stint at the Cavendish Laboratory, he collaborated with another research scholar, Ernest Walton, and together they succeeded in transmuting lithium and boron by high energy protons. Their research was instrumental in the development of nuclear power. Subsequently, he went on to head the Canadian Atomic Energy project as well as the Atomic Energy Research Establishment. Throughout his career, Cockcroft worked in a variety of capacities for both his government and is understandably regarded as one of the most important figures in atomic research in the United Kingdom. Understandably, he won plenty of accolades for his stellar scientific career.

John Cockcroft Childhood & Early Life

John Douglas Cockcroft was born on 27 May 1897, in Todmorden, England, to John Arthur Cockcroft and his wife Annie Marie Cockcroft. His father, like his ancestors, was the owner of a cotton mill. John Cockcroft had three brothers.

He attended the Todmorden Secondary School in his home town for a period of five years starting from 1909. At that school, he was taught by Luke Sutcliffe, a teacher of physics at the school who also went on to teach Nobel Laureate Geoffrey Wilkinson.

In 1914, he enrolled in Manchester University to study mathematics but after a year he had to contribute towards the war effort in relation to the First World War. He served in the capacity of a signaller at the Royal Field Artillery and returned only after he had rendered services for three years.

In 1918, he returned to Manchester after serving in the Royal Field Artillery and the following year enrolled in the University of Manchester Institute of Science and Technology to study electrical engineering. After studying engineering for a year, he did an apprenticeship at Metropolitan Vickers Electrical Company.

John Cockcroft Career

John Cockcroft won the prestigious 1851 Exhibition Scholarship awarded by the Royal Commission for the Exhibition of 1851 and went to study at St John’s College, University of Cambridge.

He studied mathematics and in 1924, took the Mathematical Tripos. Subsequently, he started working under Lord Rutherford at the Cavendish Laboratory.

In 1928, he started working on a series of experiments on acceleration of protons by high voltages. Soon, he was joined by another researcher Ernest Walton.

His experiments, in collaboration with Walton, on splitting the nucleus of an atom with the help of bombardments with protons were successful and in 1932 they demonstrated the phenomenon by performing the experiments on lithium atoms. Their experiments confirmed the existing theories on the theories on atomic structure and also showed that the nucleus of an atom could be changed in the laboratory.

He continued his research on the splitting of atoms and in 1933 he was successful in producing radioactivity with the aid of protons. In the same year, he conducted a thorough research on the different sorts of transmutations that protons and deuterons can produce. The following year was appointed as the head of the Royal Society Mond Laboratory in Cambridge.

Following the breakout of the Second World War, he was appointed as the Assistant Director of Scientific Research at the Ministry of Supply in 1939 and primarily worked on radars and air defence issues. In 1940, he went to the United States as one of the delegates for the Tizard Mission. Subsequently he was made the Head of the Air Defence Research and Development Establishment.

He became the head of the Canadian Atomic Energy project in 1944 and also became the Director of both Montreal Laboratory as well as Chalk River Laboratories. In 1946, he returned to England and became the Director of the Atomic Energy Research Establishment, Harwell.

From 1954 to 1959, he worked as a scientific researcher at the U.K. Atomic Energy Authority and even after that five year stint was over, he continued work in the capacity of a part time researcher. Following the end of his tenure as a full time researcher at the U.K. Atomic Energy Authority, he was made the Master of Churchill College at University of Cambridge following an election.

John Cockcroft Major Works

His most significant work in a career that saw him hold many responsible positions in the scientific sphere is without doubt the series of experiments with Walton that successfully split the nucleus of atoms. He shared the Nobel Prize for the same.

John Cockcroft Awards & Achievements

He was awarded the Hughes Medal in 1938.

In 1951, John Crockcroft shared the Nobel Prize in Physics with Ernest Walton for their experiments on atom splitting.

He was awarded the Royal Medal in 1954.

He won the Faraday Medal in 1955.

John Cockcroft Personal Life & Legacy

John Cockcroft married Eunice Elizabeth Crabtree in 1925. The couple had five children; four daughters and a son.

He died on 18 September 1967, at the age of 70, in Cambridge, England.
