Like John Diefenbaker, his political rival, Pearson never saw combat in the First World War. During the confusion of an air raid, he was struck by a London omnibus ending his military career.

​Former Prime Minister and Nobel Peace Prize laureate Lester B. Pearson,
served during the First World War in both the Canadian Army Medical and
the Royal Flying Corps. After the War, Pearson continued with his
academic studies and in the 1920s lectured in history at the University
of Toronto.
In the late 1920s, Pearson started what was to be a long and
productive career in the Department of External Affairs. In the late
1950s, he became the leader of the Liberal Party and succeeded John
Diefenbaker to become the fourteenth Prime Minister of Canada. Two
notable achievements of Pearson's government were the introduction of
the Canada Pension Plan and the creation of a new national flag, now
known the world-over as the quintessential symbol of Canada.
Born in
Newtonbrook, Ontario in 1897, Pearson died in Ottawa in 1972.
