Career

Detail of brake distributor Božič with lever for changing the braking force according to load.

His engineering work began immediately upon his return to the railway workshop in

First World War. After the war, he worked in Kraljevo, Belgrade and Zagreb. He applied to the International Union of Railways for a patent for the Božić brake through the Yugoslav railway in 1925. His patent was approved in 1928.[3] Božić sold his design to the Czech conglomerate Škoda Works and over time, his brake was copied and adapted by most European railways.[4]

Božić's invention resolved then unsolvable problems, such as solutions distributor (main braking device).

During World War II, the German occupying forces took over the Božić residence. Dobrivoje reportedly hid from them in a special shelter as they sought his services in order to develop a rocket engine.[2][4] At the end of the war, Božić was imprisoned; accused of collaboration and assisting in the design of the V-2 rocket.[4] He was released thanks to an intervention from the Soviets who expressed interest in his work and knowledge.[2] Upon his release, he fled with his wife Radmila and son Dragan, and eventually settled in Windsor, Ontario, Canada.[2] Božić's daughter Vesna, died in 1943 at the age of five from complications of appendicitis.[4] Dobrivoje eventually divorced his wife, who gave birth in exile to another son named Robert, and moved to the United States where he lived until 1964 when he returned to Belgrade.[2]
