Claude Valsuani (1876-1923), founder of Fonderie Valsuani, Paris - historically misidentified online as Marcello Valsuani

The Valsuani foundry was founded by Claude Valsuani (1876–1923), an Italian-born master of lost-wax (cire perdue) bronze casting, at 74 Rue des Plantes in Paris. The oft-cited founder “Marcello Valsuani” never existed: the name appears in zero of the 23 primary documents examined in this research.

A forensic investigation debunking one of art history’s most persistent myths: the existence of ‘Marcello Valsuani,’ long credited as founder of the legendary Paris bronze foundry. Through systematic
analysis of 23 primary documents (including birth certificates, passports, death records, and business correspondence) this research reveals that Marcello never existed. The name appears in zero official
documents. The real founder was Claude Valsuani (1876-1923), son of Carlo. This case study exposes how unverified claims propagate through auction catalogs and scholarly literature, crystallizing into
accepted ‘fact’ through sheer repetition. A cautionary tale about the urgent need for primary source verification in art historical scholarship.
