Task: Question Answering
Input (English): Passage: Stanford did not employ a full-time professor in religion until 1951 and did not establish a religious studies department until 1973, later than most other universities in the U.S.  Earlier courses in religion were largely offered by the chaplains of Stanford Memorial Church.  David Charles Gardner offered a course in Biblical history and literature beginning in 1907, and by 1910, he was teaching New Testament Greek and Bible classes.  Gardner's successor, D. Elton Trueblood, whose goal was the establishment of a non-denominational graduate school in religious studies at Stanford, taught classes about the philosophy of religion.  In 1941 Trueblood's efforts to expand the study of religion resulted in the creation of a minor in religion, as well as twenty-one courses offered by him and four faculty members.  By 1960, the chaplains of Stanford Memorial Church no longer had to run the program, which had expanded to allow students the option of majoring in the study of religion.  By the mid-1960s, the religious studies program at Stanford was enjoying "enormous success".In the 1960s, the study of religion at Stanford began to focus more on social and ethical issues like race and the Vietnam War.  Leading this focus was Stanford Memorial Church Dean of the Chapel and Professor of Religion B. Davie Napier, who was "a powerful critic of U.S. policy in Vietnam".  Napier, along with Stanford professors Michael Novak and Robert McAfee Brown, who had previously been faculty members of seminaries, were the subject of a Time Magazine article in 1966, describing "the renaissance of faith and learning at Stanford".  Students crowded into the church to hear anti-war speeches by them, as well as by "notables" such as Linus Pauling and William Sloan Coffin.  Harvey credited Napier for making the church a popular meeting place on campus for undergraduates and for turning it into "Christian theater—the introduction of jazz and other types of experimental worship as well as provocative preaching".Stanford University was the first major educational institution in the United States that conducted same-sex commitment ceremonies at its chapel.  Its first ceremony was held in 1993, and was officiated by Associate Dean Diana Akiyama.  In 2017, a campus organization attempted to have Stanford Memorial Church declared a sanctuary church for the undocumented immigrant student population, but was unsuccessful due to university policies regarding the status of the church as part of the university. 
Question: What is the full name of the person Trueblood replaced?
