Theodoric III of Montbéliard

Theodoric III of Montfaucon (1205–1283), called the Great Baron, was Count of Montbéliard from 1227, succeeding his father Richard III. In 1248 he founded Montbéliard's first hospital for the poor outside the city walls.

He married Alix, daughter of Count Frederick II of Ferrette. Their son Richard died before him in 1279, so in 1282 Theodoric settled the county on his great-granddaughter Guillemette de Neufchâtel; her marriage to Reginald of Burgundy carried Montbéliard into a new dynasty.
