Dr Muller graduated from the Ecole Centrale des Arts et Manufactures in Paris in 1947, and started his career as a engineer with STUP (now Freyssinet), where he worked for four years. In 1951 he moved to New York to take up the post of chief engineer for Freyssinet, before moving back to Paris in 1955 to join contractor Campenon Bernard. After 22 years as technical director for the firm, he was promoted to chief scientific director, a post he held until 1978.
In 1978, Muller teamed up with US engineer Eugene Figg to form the consultancy Figg & Muller Engineers, responsible for some of the USA's most dramatic bridge structures, including the Linn Cove Viaduct, Sunshine Skyway and H3 Viaduct in Hawaii.
When the partnership split in 1986, Muller set up his own company Jean Muller International, back in Paris, and continued designing bridges, including the cable-stayed Isere Bridge in Romans, regarded as one of Europe's finest contemporary bridges.
He is credited with developing the match-casting process for construction of segmental viaducts, as well as developing launching gantries for segmental construction and external prestressing for box girder segments. The Brotonne Bridge in France was the first cable-stayed bridge to use precast segmental construction.
