Weibull was born 18 June 1887 in the town of
Vittskövle in Sweden. (The family originated from the village "Weibøl/Vedbøl" in
Haderslev, Denmark.) He joined the
Swedish Coast Guard in 1905 as a midshipman. He moved up the ranks with promotion to sublieutenant in 1907,
Captain in 1916 and
Major in 1940. While in the coast guard he took courses at the
Royal Institute of Technology. In 1924 he graduated and became a full professor. The same technique is still used today in offshore
oil exploration. == Research contributions ==
