Trained at the School of Architecture and Fine Arts, he emigrated to Brazil in 1956 to settle in São Paulo.
It is in this city that he created his first company, the Fábrica de Móveis Cidam. Founded in 1961, the company was very successful in designing the decoration of many luxury hotels throughout the country. He then created WoodArt, a company specialized in the creation of furniture made of Brazilian rosewood and using leather, upholstery and precious woods such as rosewood.
However, it was time for originality! Its emblematic creation remains the Jangada Chair (1968), celebrated internationally with numerous awards and designed on the model of a traditional Brazilian fishing boat. It consists of an armchair and its ottoman supported by nylon nets.
Jean Gillon died in 2007.
