Born about the year 1029, at Champagne, France, of noble parents who bore the names of Thierry and Ermengarde; died at Molesme, 17 April 1111. When fifteen years of age, he commenced his novitiate in the Abbey of Montier-la-Celle, or Saint Pierre-la-Celle, situated near Troyes, of which he became later prior. In 1068 he succeeded Hunaut II as Abbot of Saint Michael de Tonnerre, in the Diocese of Langres. About this time a band of seven anchorites who lived in the forest of Collan, in the same diocese, sought to have Robert for their chief, but the monks, despite their constant resistance to his authority, insisted on keeping their abbot who enjoyed so great a reputation, and was the ornament of their house. Their intrigues determined Robert to resign his charge in 1071, and seek refuge in the monastery of Montier-la-Celle. The same year he was placed over the priory of Saint Ayoul de Provins, which depended on Montier-la-Celle. Meantime two of the hermits of Collan went to Rome and besought Gregory VII to give them the prior of Provins for their superior. The pope granted their request, and in 1074 Robert initiated the hermits of Collan in the monastic life. As the location at Collan was found unsuitable, Robert founded a monastery at Molesme in the valley of Langres at the close of 1075. To Molesme as a guest came the distinguished canon and doctor (écolâtre) of Reims, Bruno, who, in 1082, placed himself under the direction of Robert, before founding the celebrated order of the Chartreux. At this time the primitive discipline was still in its full vigour, and the religious lived by the labour of their hands. Soon, however, the monastery became wealthy through a number of donations, and with wealth, despite the vigilance of the abbot, came laxity of discipline. Robert endeavoured to restore the primitive strictness, but the monks showed so much resistance that he abdicated, and left the care of his community to his prior, Alberic, who retired in 1093. In the following year he returned with Robert to Molesme. On 29 November 1095, Urban II confirmed the institute of Molesme. In 1098 Robert, still unable to reform his rebellious monks, obtained from Hugues, Archbishop of Lyons and Legate of the Holy See, authority to found a new order on new lines. Twenty-one religious left Molesme and set out joyfully for a desert called Cîteaux in the Diocese of Châlons, and the Abbey of Cîteaux was founded 21 March 1098.
Left to themselves, the monks of Molesme appealed to the pope, and Robert was restored to Molesme, which thereafter became an ardent centre of monastic life. Robert died 17 April 1111, and was buried with great pomp in the church of the abbey. Pope Honorius III by Letters Apostolic in 1222 authorized his veneration in the church of Molesme, and soon after the veneration of Saint Robert was extended to the whole Church by a pontifical Decree. The feast was fixed at first on 17 April, but later it was transferred to 29 April. The Abbey of Molesme existed up to the French Revolution. The remains of the holy founder are preserved in the parish church.
