Profoto was founded in 1968, in Stockholm, by photographer and engineer Eckhard Heine and photo equipment retailer Conny Dufgran, both Swedish. Their relationship started out with mr Dufgran selling mr Heine a new flash unit - that didn't work. Annoyed with the failing unit, mr Heine went home and invented a new type of flash, with the focus on durability. Simply by walking around in Stockholm for two weeks, he immediately sold 25 units. Profoto was born - with a bang - and a few months later Eckhard Heine and Conny Dufgran launched the new Pro-1 generator internationally at the Photokina trade show in Cologne.
