Gustaf Dal%C3%A9n

Nils Gustaf Daln was a Swedish Nobel Laureate and industrialist, the founder of the AGA company and inventor of the AGA cooker and the Daln light. In 1912 he was awarded the Nobel Prize in Physics for his invention of automatic regulators for use in conjunction with gas accumulators for illuminating lighthouses and buoys.

Daln was born in Stenstorp, a small village in Falkping Municipality, Vstra Gtaland County. He managed the family farm, which he expanded to include a market garden, a seed merchants and a dairy. In 1892 he invented a milkfat tester to check milk quality of the milk delivered and went to Stockholm to show his new invention for Gustaf de Laval. de Laval was impressed by the selftaught Daln and the invention and encouraged him to get a basic technical education. He was admitted to the Chalmers University of Technology where he earned his Masters degree and a Doctorate on leaving in 1896. Daln was much the same type of inventor as Gustaf de Laval, not afraid of testing impossible ideas, but Daln was much more careful with the company economy. The products should have a solid market place before he introduced a new product.
