May 25, 1930
Archduke Rainer Karl of Austria died today in a Vienna hospital. He was 35.
He was a son of Archduke Leopold Salvator, according to a wireless dispatch to the New York Times. After the World War, he chose to drop his title, and "devote himself to motor transport with considerable success." He also organized a system of motorcycle transport of film reels, which allowed for several movie theatres to show the same film "at practically the same time."
In February 1929, Rainer Karl was involved in a traffic accident, which was reported by the Times.
The cause of death was not announced.
Rainer Karl was the fourth of ten children of Archduke Leopold Salvator and Infanta Blanca of Spain. He was born at Zagreb on November 21, 1895. He was unmarried.
