A Canadian Minister of National Defence who steered the country's military through the tense early years of the Cold War and the seismic political crisis of the Cuban Missile Crisis.
Douglas Harkness entered politics with the sober demeanor of a man who had seen war, serving as an artillery officer in World War II. That experience defined his subsequent parliamentary career, which was largely dedicated to matters of defence and veterans' affairs. Elected as a Progressive Conservative, he represented his Alberta riding for over two decades. His most significant and tumultuous role came as John Diefenbaker's Minister of National Defence. Harkness was a staunch Atlanticist and advocate for nuclear arms for Canadian forces, a position that placed him on a collision course with the increasingly hesitant Prime Minister during the Cuban Missile Crisis. Their very public disagreement over alert levels and weaponry culminated in Harkness's principled resignation in 1963, an act that helped trigger the fall of Diefenbaker's government. He left politics as a figure of conviction, respected for his directness and dedication to what he believed was essential for national security.

Douglas was born in 1903, placing them squarely in The Greatest Generation. The events that shaped this generation — world wars, depression, and rapid industrialization — shaped the world they entered and the choices available to them.
