Born in 1942, Weisbecker studied interior design in Paris. By 1968 he moved to New York. First working as a draftsman in an architectural firm, he started a career as an illustrator at the age of 30.
His work has been published in major American publications such as the New York Times, Time magazine and The New Yorker among others.
In the late 90's he shifted gradually from commissioned work to his own original production which he is now showing in galleries worldwide. Moving back to France in 2006, he is now sharing his time between Paris and Barcelona.
