Marc "Boy-boy" Wallenberg[1] RVO (28 June 1924 – 19 November 1971) was a Swedish banker and business manager.

Wallenberg passed studentexamen in 1943 and graduated from Harvard Business School in 1949 before bank studies in New York City, Geneva, Paris, London and Düsseldorf from 1949 to 1952,[2] all according to his father's plan.

Jacob Palmstierna and Peder Bonde, both Deputy CEO's of SEB, arrived at the site at 12 o'clock and were the first to see Wallenberg's dead body near his car and could confirm his identity.

Marcus Wallenberg considered that his son's prolonged cold and medication with sulfa drugs might have been fatal.
