Nils Gustaf Dalén (30 November 1869 – 9 December 1937) was a Swedish Nobel Laureate and industrialist, the founder of the AGA company and inventor of the AGA cooker and the Dalén 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".
Dalén was born in Stenstorp, a small village in Falköping Municipality, Västra Götaland 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 milk-fat tester to check milk quality of the milk delivered and went to to show his new invention for Gustaf de Laval. de Laval was impressed by the self-taught Dalén 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 Master's degree and a Doctorate on leaving in 1896. Dalén was much the same type of inventor as Gustaf de Laval, not afraid of testing "impossible" ideas, but Dalén was much more careful with the company economy. The products should have a solid market place before he introduced a new product.
In 1906 Dalén became chief engineer at the Gas Accumulator Company (manufacturer and distributor of acetylene) and in 1909 when AGA was founded, he was appointed the managing director for the company. During his life, AGA was one of the most innovative companies in Sweden and produced a large variety of products that grew every year. Finally in the early 1970s AGA was forced to reduce the number of markets it was involved in and concentrate on the production of gases for industrial use.
In 1909 he ascended to the position of Managing Director of the renamed company Svenska Aktiebolaget Gasaccumulator (AGA). AGA developed lighthouses using Dalén's products. In 1910 the company bought a large real estate in Lidingö and built a production plant that was completed around 1912, when they moved out from the facilities in Stockholm.
