On Monday, January 15, Americans will celebrate the life and achievements of civil rights leader Martin Luther King Jr. (MLK). Born in Atlanta, Georgia on January 15, 1929, the activist was originally named Michael King after his father, a pastor at Ebenezer Baptist Church. However, after a trip to Europe in 1934, King Sr. changed both his and his son’s name to Martin Luther in honor of the German theologian who initiated the Protestant Reformation in the 16th century.
