John Gualbert was an 11th-century Italian Benedictine monk and abbot who was born into the noble Visdomini family near Florence. After choosing to renounce a path of vengeance on Good Friday, he entered the Benedictine Order at San Miniato. He is most recognized for establishing the Vallumbrosan Order in 1036. Throughout his religious life, he was a dedicated reformer who actively fought against the practices of nepotism and simony within the church.
Life and work

Born around 985 in Poggio Petroio, John dedicated his life to monastic reform. After joining the Benedictines, he founded his own order, the Vallumbrosans, in 1036. He spent his years advocating for ecclesiastical integrity, specifically targeting corruption and the sale of church offices. He passed away in Tavarnelle Val di Pesa on July 12, 1073.
Veneration and patronage

He was canonized as a saint by Pope Celestine III in 1193. Because of his connection to nature and the monastic lifestyle, he serves as a patron for foresters, park rangers, the Italian Forest Corps, and the forests of Brazil. His feast day is observed annually on July 12 in both Catholic and Anglican traditions.
