Early Career
Johns' graduation coincided with the start of World War II. For the duration of the war, he taught physics, mathematics, radar systems, and radio navigation to newly recruited airplane pilots as part of the British Commonwealth Air Training Plan. Based on his radiography and physics experience, Johns was also involved in non-invasive X-ray testing of metal aircraft castings. A meeting in August 1946 with William Valentine Mayneord, while Mayneord was at the Atomic Energy Project at Chalk River, Ontario, contributed to Johns's making a career in medical physics.
Johns married his wife, Sybil Hawkins Johns, in 1940. Their marriage lasted until Johns's death fifty-eight years later.

Famous quotes containing the words early and/or career:
“the cluttered eyes
of early mysterious night.”
—Imamu Amiri Baraka (b. 1934)
“I seemed intent on making it as difficult for myself as possible to pursue my “male” career goal. I not only procrastinated endlessly, submitting my medical school application at the very last minute, but continued to crave a conventional female role even as I moved ahead with my “male” pursuits.”
—Margaret S. Mahler (1897–1985)
