Bennett Lewis
Wilfrid Bennett Lewis, CC CBE FRSC FRS (June 24, 1908 – January 10, 1987) was a Canadian nuclear scientist and administrator, and was centrally involved in the development of the CANDU reactor.
Born in Castle Carrock, Cumberland, England, he earned a doctorate in physics at Cavendish Laboratory, University of Cambridge in 1934, and continued his research in nuclear physics there until 1939. From 1939 until 1946, he was with the Air Ministry, becoming Chief Superintendent of the Telecommunications Research Establishment. In 1946, he moved to Canada, to become director of the division of Atomic Energy Research at the National Research Council of Canada in Chalk River, Ontario. From 1952 until 1963, he was Vice President, Research and Development of the Atomic Energy of Canada Limited, and was Senior Vice President, Science from 1963 until 1973.
Starting in the mid-1940s, Lewis directed the development and championed the CANDU system, with its natural uranium fuel moderated by heavy water (deuterium oxide) to control neutron flux. The CANDU has proven its value for commercial power applications, showing outstanding efficiency and safety records. AECL also became a world leader in the production of radioisotopes for medical purposes.
From 1973 until his death in 1987, Lewis was a Distinguished Professor of Science at Queen's University.
From 1955 until 1987, he was the Canadian Representative on the United Nations Scientific Advisory Committee.
In 1994 a biography of Lewis entitled Nuclear Pursuits was published Ruth Fawcett.

Famous quotes containing the words bennett and/or lewis:
“He said “Next time can I bring my friend?”
And I thought “Does he mean friend?”
And I thought “Yes he does mean friend.”
Which was quite bold in those days.
It was the Dark Ages. Men and men.
And they could still put you in prison for it.
And did, dear.”
—Alan Bennett (b. 1934)
“When we say “science” we can either mean any manipulation of the inventive and organizing power of the human intellect: or we can mean such an extremely different thing as the religion of science the vulgarized derivative from this pure activity manipulated by a sort of priestcraft into a great religious and political weapon.”
—Wyndham Lewis (1882–1957)
