The Massiers (Jerome, Clement, Delphin, Cedric) are a dynasty of ceramists who go back beyond the French Revolution and who played a key role in the renaissance of Vallauris ceramics.

Clément Massier is considered the founder of the modern ceramic industry in Vallauris at the beginning of the 20th century. Naturally creative, Clément Massier (1844 Vallauris - 1917 Golfe-Juan) was first a worker from 1856 with his father Jacques (1801-1871). He was introduced to pottery by Gaetano Gandolfi, an Italian master ceramist hired by his father. Gandolfi was the initiator of several techniques, including glazed earthenware, which made the Massier company famous. From then on, the production was distinguished by its originality, abandoning utilitarian pottery in favor of an exclusively artistic creation.

The three Massier companies, managed by the brothers Clément and Delphin and cousin Jérôme, soon became one of the major producers in Vallauris.
