Rudolf Caracciola victoriously crosses the finish line before a crowd of more than 250,000.

By race time, the sun that had brightly illuminated the practice runs was masked by dark fog and drizzle — a profound foreshadowing of the upcoming war and a reflection of the mood at what would be Germany’s last Grand Prix before the outbreak of hostilities.

World War Two would put an end to the Grand Prix until 1946. The German Grand Prix was Caracciola’s final win.
