Dag Hagenaes-Kjelldahl started out flying an air taxi in the Caribbean, after which he became a journalist with a Norwegian newspaper. He then studied to become a meteorologist in the Arctic. Dag spent two years in isolation on the Bear Island weather station, collecting fossils and setting up a local museum in his spare time. He discovered the camp-site of the marooned crew from the Dutch ship The Young Eagle, wrecked in 1700. Half the crew succumbed to exhaustion, drowning and scurvy as they tried to survive the very first wintering on the Arctic island.
After nine years of teaching, Dag built the first Norwegian hands-on science museum Teknoteket, which each year was visited by 140 000 people including 40 000 in school groups. The Teknoteket Science Circus visited schools all over the country with an eighteen- wheeler trailer truck with hands-on science exhibition and several teachers who provided courses for teachers.
From 1999 Dag has been developing the Whitby Wizard Science Centre project, building more than a hundred interactive exhibits of science and human perception. An increasing number of school groups from out of town visit the only science centre in North Yorkshire, many of them returning year after year.
