Martin Luther King, Jr., was born on January 15, 1929, in Atlanta, Georgia. He was the son of the Reverend Martin Luther King, Sr. and Alberta Williams King. King's father was born "Michael King," and Martin Luther King, Jr., was originally named "Michael King, Jr.," until the family traveled to Europe in 1934 and visited Germany. His father soon changed both of their names to Martin in honor of the German Protestant leader Martin Luther. He had an older sister, Willie Christine King, and a younger brother Alfred Daniel Williams King. King sang with his church choir at the 1939 Atlanta premiere of the movie Gone with the Wind.
Growing up in Atlanta, King attended Booker T. Washington High School. He skipped ninth and twelfth grade, and entered Morehouse College at age fifteen without formally graduating from high school. In 1948, he graduated from Morehouse with a Bachelor of Arts degree in sociology, and enrolled in Crozer Theological Seminary in Chester, Pennsylvania, from which he graduated with a Bachelor of Divinity degree in 1951. King then began doctoral studies in systematic theology at Boston University and received his Doctor of Philosophy on June 5, 1955. A 1980s inquiry concluded portions of his dissertation had been plagiarized and he had acted improperly but that his dissertation still "makes an intelligent contribution to scholarship."
King married Coretta Scott, on June 18, 1953, on the lawn of her parents' house in her hometown of Heiberger, Alabama. King and Scott had four children; Yolanda King, Martin Luther King III, Dexter Scott King, and Bernice King. King became pastor of the Dexter Avenue Baptist Church in Montgomery, Alabama when he was twenty-five years old in 1954.
