Next Wednesday the Church celebrates the feast day of St. Peter Claver (1581-1654). He was born in Catalonia, Spain of impoverished parents, went to a Jesuit college in Barcelona and soon developed a burning desire to go to the New World and minister to the African slaves. He ended up in Cartagena, a Caribbean port in modern-day Colombia, that served as a chief slave market. Soon the saint was going out to the slave ships to offer prayers and assistance. It is said that St. Peter Claver baptized and instructed over 300,000 slaves. For a short biography see New Advent Encyclopedia and this video biography offered by Catholic Online.
