Biography

John Yi Mun-u was orphaned as a child and raised by a Catholic woman in Seoul. After the deaths of his wife and children, he devoted himself to charitable work and helping missionaries. He accompanied Pierre Maubant on pastoral visits, collected assistance for prisoners, and helped conceal missionaries during persecution.

John also risked his safety to bury the bodies of Bishop Imbert, Maubant and Chastan. Arrested in November 1839, he refused inducements to renounce Catholicism and encouraged fellow prisoners. A prison letter recorded in the bishops' biography expresses his concern for their perseverance. He was executed at Tangkogae in February 1840.
