As a boy, James Hillier thought he would wish to be a commercial artist. Instead, he turned turn out to boast a talent for mathematics and physics, and won a scholarship scholarship to the University of Toronto. There, he and fellow student Albert Prebus invented the worlds prime(prenominal) practical electron microscope. Â Â Â Â Â Â Â Â Electron microscopes cultivate by counsel a actinotherapy of electrons, rather than a beam of light. The wavelength of electrons is much(prenominal) littler than the wavelength of light, enabling greater magnification and depth of focus. In 1938, Hillier and Prebus produced a microscope that worked by passing a beam of electrons by dint of a care full(a)y prepared sample. The beam was then cerebrate on a photographic plate. Their device-magnified objects to 7,000 times their size C optic microscopes produced a magnification of only 2,000 times. A hardly a(prenominal) age later, Hillier and two other physicists developed what was arguably the beginning(a) scan electron microscope. This worked by scanning the object with a beam of electrons to produce an image similar to the one on a television screen. Â Â Â Â Â Â Â Â After he retired, Hillier devoted himself to promoting information teaching.
He now gives talks to high school students about(predicate) careers in science. Because he would never have been able to go to university without scholarships, he established the James Hillier Foundation, which awards scholarships to promising science students in his hometown of Brantford. The knowledgeableness supports 10 science students in their pursuit of university education with $! 5,000 annually. His work has brought him many honors, including the Order of Canada .
