Paul Chong Hasang was a philosopher and lay missionary in Joseon who lived from approximately 1795 to 1839. The son of the martyr Augustine Chong Yakjong, he worked as a government interpreter and traveled to Beijing to facilitate contact with missionaries. He studied theology and Latin under Imbert and actively advocated for the establishment of a Korean diocese by petitioning Pope Gregory XVI. During periods of intense persecution, he remained a steadfast defender of the Catholic faith until his death in Seoul.
