In the life of Pierre Jeanniot there are plenty of lessons in how to make something of oneself: how to think clearly, work hard, succeed. Jeanniot came from circumstances that were not desperate per se, but not all that promising, either. Yet as a young technician in Montreal, he invented the “black box” flight recorder and, as president of Air Canada, he instituted computer reservation systems and no-smoking flights. The latter initiative was so successful it’s hard to imagine now that people ever smoked on planes.
