## Bio

Nils Gustaf Dalén was born in Sweden on 30 November 1869, trained as an engineer, and turned his attention to a problem most people never considered: how to keep remote lighthouses burning reliably without constant human tending. His invention of automatic regulators for gas accumulators—devices that controlled when the flame lit and when it died—revolutionized maritime safety by letting beacons operate unattended. The work earned him the Nobel Prize in Physics in 1912. He died on 9 December 1937.
