He taught himself to fly and set several records for endurance flights before founding his own airplane manufacturing company.
His company manufactured the Sopwith Camel and the Triplane during World War I and the Hurricane Fighter and Lancaster Bomber during World War II.
His father was killed in a tragic accident when Sopwith was just ten years old.
He and William Boeing were both pilots-turned-airplane-manufacturers.
