Robert Pierce (1914–1978) was an American Baptist minister and relief worker. He is best known as the founder of the international charity organizations World Vision International in 1950 and Samaritan's Purse in 1970.
Pierce was born in Fort Dodge, Iowa. He moved with his family to southern California in the mid-1920s. He attended Pasadena Nazarene College and studied for the ministry. From 1937 to 1940 he spent time traveling across California working as an evangelist. In 1940 he was ordained into the Baptist ministry and soon thereafter he became involved with the Los Angeles branch of the WWII-era “Youth for Christ” (YFC) movement.
In 1947, Robert Pierce joined Youth for Christ, in a series of evangelical rallies held in China. On the trip, he met Tena Hoelkeboer, a missionary teacher. She presented him a battered and abandoned child. Unable to care for the child herself, Tena asked Pierce, "What are you going to do about her?" Pierce gave the woman his last five dollars and agreed to send the same amount each month to help the woman care for the child.
He was deeply affected by the poverty and human suffering that he witnessed. In 1950 he founded World Vision International.
In 1959 journalist Richard Gehman wrote that "[Pierce] cannot conceal his true emotions. He seems to me to be one of the few naturally, uncontrollably honest men I have ever met." Pastor Richard Halverson wrote that Pierce "prayed more earnestly and importunately than anyone else I have ever known. It was as though prayer burned within him. … Bob Pierce functioned from a broken heart."
Pierce was also a filmmaker and during his leadership World Vision used movies, shown mainly for church audiences, as the main marketing tool. Since in the worldview of Pierce Christianity was the only religion able to counter communism, these movies were full of anti-communist cold war rhetoric and promoted Christian missionizing as a way to counter communism. In particular, movies like "The Red Plague" or "The Poison of Communism" radicalized originally apolitical evangelicals and the movies used by World Vision at that time can therefore also be seen as political propaganda movies. With the extensive use of movies as funding tool, Bob Pierce's World Vision had together with the Salvation Army a leading role in the development of the evangelical social action movie.
