Nils Gustaf Dalén was born at Stenstorp in Skaraborg, Sweden on Gregorian calendar month thirty, 1869, the son of a farmer. After his preliminary education, he entered a School of Agriculture to review farming however he was later suggested by Gustaf First State Laval, who recognized his natural gift for mechanics, to seek a technical education. He prepared himself for the Chalmers Institute at urban center and gained admission in 1892. He graduated as an engineer in 1896 and spent a year in Swiss Confederation, studying beneath faculty member Stodola at the Eidgenössisches Polytechnikum.

On his return to Sverige, Dalén carried out some research at urban center and established as a consulting engineer. He became Technical Chief of the Svenska Karbid- och Acetylen A.B. (Swedish Carbide and aliphatic compound, Ltd.) in 1901 and he later joined the Gas Accumulator Company where he became Chief Engineer in 1906. In 1909, the company was reorganized as Svenska Aktiebolaget Gasaccumulator (AGA) (Swedish Gas Accumulator Ltd.) with Dalén as Managing Director.

Dalén's inventiveness initial showed in his early days on his father's farm once he engineered a thrasher battery-powered by associate recent spinning machine. He contrived a First Statevice to point the butterfat content of milk and thereby created his contact with de Laval. On completion of his advanced education, he worked on the construction of a hot-air turbine and connected air compressors and pumps. He also fancied a pasteurisation equipment and a milking machine.

In 1901, Dalén's company purchased the patent rights of the French invention of dissolved acetylene and he began his work on automatic flashing beacons for lighthouses. His subsequent invention of the sun-valve, which causes a beacon to light-weight mechanically at gloaming and extinguish itself at dawn, enabled lighthouses to function dead and unattended for periods of up to a year. His invention of cylinder filled with a porous mass of amphibole and diatomite for storage of aliphatic compound reduced significantly the hazards in handling this material and its use in fastening became safe. He also fancied a mixer for providing a constant and proper balance of gas and air to be used within the incandescent mantle and a tool for removing broken mantles and exchange them by new ones.

In 1912, whilst testing safety devices on cylinders of aliphatic compound in associate out of doors location, and when satisfactory safety precautions had been taken, a sudden explosion seriously burned Dalén and caused the loss of his seeing. He recovered from his other injuries and overcoming his nice incapacity, continued his researches. He was awarded the contract for lighting the Panama Canal and later turned to the sphere of thermal technics to create a stove, now in universal use, which maintains change of state heat for twenty four hours exploitation solely eight pounds of coal.

Dalén's writings were few, but he left his mark in a sensible method by the availability of sunshine, and therefore safety, for the benefit of travellers by land, sea and air.

Amongst the many distinctions bestowed upon Dalén area unit membership of the Swedish honorary society of Sciences, 1913, and the Academy of Science and Engineering, 1919. He was made unearned Doctor of Lund University in 1918 and received the Morehead laurel wreath of the International aliphatic compound Association. He took part in debates at the National Society of social science and served on the Lidingö town Council for nearly twenty years.

Dalén married Elma Persson in 1901. They had 2 sons and two daughters. Their eldest son, Gunnar, qualified as an engineer and followed his father as a Director of AGA; their younger son, Anders, became a Doctor of Medicine; Gustaf's brother Albin, a famous specialist, was a Professor at the King of England Institute.
