Born in France, the son of a German father and a French mother, he spent his early life in Brazil, and debuted in comics magazines in that country and executing LP covers in the 1960s.
From 1975 he worked for the experimental Metal Hurlant magazine with series including that of the punk rocker Heilman where Voss incorporates swastikas and other Nazi fanfare.
He returned to Brazil in 1981, and during the rest of his life collaborated with Brazilian publishers such as Editora Ondas and Press-Maciota.
In 2009 he suffered a first stroke: after recovering, he launched the series Anarcity, influenced by Philip K. Dick's works, and the strip Zensetos.
Voss spent the last part of his life in Lisbon, Portugal, where he died of a stroke in May 2011.
