Louis Baillon was a French designer whose work had a significant impact on the fields of furniture and lighting during the mid-20th century. His career began in 1952 when he collaborated with Charles Ramos as an interior designer, taking part in complete design projects and participating in exhibitions such as the Salon des Arts Ménagers and the Salon des Artistes Décorateurs.

Baillon later became known for designing lighting systems for Robert Caillat, including a notable parquet floor lamp. He also met Jean-Boris Lacroix, with whom he collaborated at Luminalite, creating many lamps, including the famous applique 267, made from Perspex and secured with golden bronze screws.

In the 1950s, Baillon worked with industrial companies like Usines Réunies and DSM, designing furniture and seating models that were showcased at ACMS exhibitions. In the 1960s, he partnered with Planform to develop a complete range of modular furniture, including coffee tables, benches, and planters.

One of his most iconic creations is a pair of 1950s armchairs upholstered in blue fabric, now considered rare and valuable pieces of French design from that period.

Though personal details of his life remain limited, Louis Baillon is remembered as a key figure in mid-20th-century French design.
