Neuberth's mother was a French teacher at Lycée Lakanal and a first-rate harpsichordist. His father was a first violin of Concerts Colonne, a vila alta soloist, which explains his early orientation for music and jazz in particular. An encounter with abstract painter, Henri-Jean Closon (Liège 1888 - Paris 1975) made him discover painting. On seeing him again in 1941 he decided in 1942 to devote all his time to painting. During the 70's, he abandoned gouache and centered his works on sketching and pasting.
He was qualified to be "one of the most active representatives of abstract lyrics" by Pierre Carmes in 1993.
In the 1970s, he illustrated works for the Bibliophile Circle in Geneva, the Book Guild in Lausanne, or for the Sacred Music Encyclopedia (La Bergère, Paris), as well as for the international magazine of poetry, Caractères.
In spite of several health problems such as a hemiplegia,
he never abandoned his artistic expression until his death in 1996.
In 2002, from April 20 through May 20, a posthumous exhibit, which took place at Place Neuve Gallery at Vers-Pont-du-Gard, draws a retrospective of some of his works entitled Jean Neuberth -
gouaches and drawings 1959-1992.
