Daryl Kenneth "Doc" Seaman OC AOE (28 April 1922 – 11 January 2009) was a Canadian engineer, oilman, and hockey executive.

Seaman was the founder, president, and chairman of Bow Valley Industries, one of Canada's largest independent petroleum companies.

In addition to his business activities, from 1941 to 1945 he served as a pilot in the Royal Canadian Air Force and from 1980 to 2009 was a part-owner of the Calgary Flames.

After the United States entered the War on 6 April 1917, he returned stateside, joined the army, and fought with the American Expeditionary Forces in Germany.

Seaman graduated high school in the spring of 1939, months before Canada entered World War II on 10 September 1939.

Because of his high marks in math and physics, the recruiter suggested that Seaman enlist in the Air Force.

Shortly after finishing his training, Seaman was sent to Halifax, Nova Scotia, where he spent his twentieth birthday.

By that fall Seaman's initial training was complete, and he was sent to RAF Silloth and assigned to a Lockheed Hudson as part of a four-man crew.

Taking classes during the summers as well, Seaman completed his degree in three years, graduating in the spring of 1948.

Seaman and Warnke had half of the capital they required to purchase a new seismic rig, and were unable to get a loan from an Edmonton bank.

Travelling to Calgary in the spring of 1949, Seaman acquired a loan from a small insurance company and ordered a Mayhew rig through Seismic Service Supply.

Bow Valley's largest discovery came in early 1975 when they struck oil in the North Sea off the coast of Scotland.

Joining with two Norwegian companies Bow Valley constructed the semi-submersible it named the "Odin Drill."

Beginning drilling in September 1974 and taking eight months, Bow Valley discovered a massive field which flowed 22,000 barrels a day.

Seaman was a lifelong hockey enthusiast and in his youth had been asked to sign a protection card with the New York Americans.

Later in life, Seaman was part of the group that purchased the Atlanta Flames in May 1980 and relocated the team to Calgary.

In 1993 Seaman was made an Officer of the Order of Canada, and in 2010 was posthumously inducted into the Hockey Hall of Fame.
