Mária Molnár, born in 1886, was the most notable Hungarian missionary of the Reformed Church in Hungary, and was the only Hungarian missionary who undertook a mission between the two World Wars. Molnár used the knowledge she acquired as a voluntary nurse during World War I in her mission work on the Manus and Pityilu Islands of the Admiralty Islands, ultimately becoming a martyr of the Reformed Church in Hungary during the Pacific theater of World War II.
