(b. 13/12/1944, Brazil) A few years after receiving his degree as mechanical engineer, Luiz Eduardo de Oliveira (Léo) was forced to flee from Brazil because of his political activities during the military dictatorship. He went to Chile, but a year later he headed for Argentina after the coup, and then returned to Brazil illegally in 1974. At this time, he started a job as an advertising artist in Sao Paulo. He did his first comic art for the magazine O Bicho.
In 1981, Luiz Eduardo de Oliveira moved to Paris and started to make comics more professionally. Unfortunately, the golden days of European comics had just passed, so he started working in the advertising industry again. From time to time, he made a story for magazines like L'Écho des Savanes and Pilote. In 1986, Jean-Claude Forest asked him to draw a few stories for Okapi, which led to a regular collaboration with the publishing group Bayard Presse. He illustrated short stories, and did a comics biography of 'Gandi' with Benoît Marchon in Astrapi in 1988.
In that same year, Léo associated himself with scenario writer Rodolphe, which led to the creation of the series 'Trent' for Dargaud. Also for Dargaud, Léo created the science-fiction series 'Le Cycle d'Aldebran' from 1994 to 1998, which was followed by a second cycle, 'Bételgeuse,' in 2000. He also worked with Rodolphe again on the exotic 'Kenya'. In 2002, he took on the scriptwriting of the series 'Dexter London', which is illustrated by the Spanish artist Sergio Garcia.
