Johan Adolf Dahlgren was the son of Bernard Ebbe Dahlgren and Anna M. Neuhauser. Born in 1744 in Norrköping, a town on the Baltic coast to the southwest of Stockholm, he was educated by private tutors and then studied chemistry and pharmacy with the Admiralty chemist in Stockholm. He enrolled at the University of Uppsala on November 2, 1764, became a protégé of the famous naturalist Carolus Linnaeus, and graduated as a medical doctor in 1775. This extended course of study prepared him for the rigors of medicine, and the faculty soon held Doctor Dahlgren in great esteem. On October 14, 1789, Dahlgren was appointed Chief Physician and Assessor of the Province of Finland, where he lived out the rest of his life. Johan Adolph married Maria Rådde, the daughter of a fabric dyer Stockholm. He died on May 14, 1797 at the relatively young age of 53, “much respected by the authorities, and beloved by the poor, who in a large body followed his remains to the grave,--a civic funeral having decreed him by the town Uleåborg, where he had resided.”
