Dalén, Nils

Swedish physicist

in full Nils Gustaf Dalén

born Nov. 30, 1869, Stenstorp, Sweden

died Dec. 9, 1937, Stockholm

Swedish engineer who won the Nobel Prize for Physics in 1912 for his invention of the automatic sun valve, or Solventil, which regulates a gaslight source by the action of sunlight, turning it off at dawn and on at dusk or at other periods of darkness. It rapidly came into worldwide use for buoys and unmanned lighthouses.

In 1906 Dalén became chief engineer of the Gas Accumulator Company, which marketed acetylene gas. He became managing director of the company in 1909 and then invented Agamassan, a substance that absorbs acetylene, making it possible to concentrate the gas with no danger of explosion. He was blinded by an explosion during an experiment in 1913, but he continued experimental work until his death.
