John Herbert Chapman (August 28, 1921 – September 28, 1979) was a Canadian space researcher.
After his studies at university, Chapman got his first position in the government with the Defence Research Board (DRB).
The DRTE having no experience developing satellites had to work quite hard to think of and counter all the difficulties they would face in the harsh environment of space.
The first was given by the Royal Society of Canada in 1966; he also received an Engineering medal from the Association of Professional Engineers of Ontario and the Dillinger Gold Medal from the International Union of Radio Scientists the same year.
One of the most important Canadian projects is Canadarm, which has become used frequently on the International Space Station (or ISS for short).
