Clodoald (Latin: C(h)lodoaldus, Cloudus; reconstructed Frankish: *Hlōdōwald; 522 – c. 560 AD), better known as Saint Cloud (French: [klu]), was a Merovingian prince, grandson of Clovis I and son of Chlodomer, who preferred to renounce royalty and became a hermit and monk. Clodoald found a hill along the Seine, two leagues below Paris, in a place called Novigentum (the present commune of Saint-Cloud). Here, among the fishermen and farmers, he led a life of solitude and prayer, and built a church, which he dedicated in honor of Martin of Tours.

He is venerated as a saint in both the Catholic and Orthodox Churches. (Full article...)
