St. Berthold of Mt. Carmel (d. 1195), also known as Bartoldus of Calabria, was born in France, the son of a Count. He excelled at his studies and was ordained a priest. Berthold's brother, Aymeric, became the Latin patriarch of Antioch. The two joined together to participate in a Crusade to the Holy Land. While in the Holy Land, Berthold traveled to Mount Carmel and built a monastery and church dedicated to the Prophet Elijah. He gathered together a number of hermits scattered throughout Palestine to live together in imitation of the life of the great prophet as recorded in the Old Testament. Berthold became the group's superior and stayed with the community at Mount Carmel for 45 years until his death in 1195. It was the life and work of St. Berthold that laid the foundation for the Carmelite Order, whose rule was approved by Pope Honorius III in 1226. St. Berthold's feast day is March 29.
