Johannes Evangelista Gossner (1773–1858) was a German pastor, missionary leader, and writer, originally trained as a Catholic priest before becoming a Protestant minister. Known for his deep piety and evangelistic zeal, he founded the Gossner Missionary Society in Berlin in 1836, which sent missionaries to India and other regions, often laymen with practical skills as well as spiritual devotion. Gossner also wrote devotional works that emphasized simple faith and Christian service. His legacy lives on through the missionary and charitable work carried forward in his name.
