The first of three 1949 Buenos Aires Grand Prix (official name: III Gran Premio del General Juan Perón y de la Ciudad de Buenos Aires) was a Grand Prix motor race that took place on January 30, 1949, at the Palermo street circuit in Buenos Aires, Argentina.[1]
The event was marred by the death of popular French driver Jean-Pierre Wimille. He was driving his first flying lap during practice, when his car swerved to avoid children crossing the track, and slammed into a tree. He died instantly of massive head injuries. During the race, local driver Pablo Pessatti was also killed when his car overturned, and he was thrown out.
