Juan Manuel Bordeu was born in Balcarce, Buenos Aires. A protégé of Juan Manuel Fangio, Bordeu had a successful early career racing in Formula Junior. He came to Europe to race a Stanguelini in Fromula Junior and was due to drive the UDT Laystall team Lotus in the French Grand Prix in 1961 but had a terrible accident in testing at Goodwood. The car was eventually driven by Lucien Bianchi and Bordeu never got another chance in F1.
In 1963 he drove a Scuderia Centro Sud Ferrari 250 GTO with Carlo Maria Abate in the 12 hour race at Sebring finishing 5th over all and first in class. He also drove a privately entered GTO in the Targa Florio that year finishing 6th overall and second in class.
He raced on in Turismo Carretera, winning the title in 1966 for Chevrolet, and the Argentine Temporada series where he drove amongst other cars, a Brabham BT23C FVA for Frank Williams, before retiring in 1973. Bordeu was the 1st President of the Juan Manuel Fangio Foundation and went on to represent Argentina as a FISA member and held a seat on the World Motorsport Council.
