Christopher D'Olier Reeve (September 25, 1952 - October 10, 2004) was an American actor. He achieved stardom for his acting achievements. In particular, he is best known for his motion picture portrayal of the classic DC comic book superhero Superman, beginning with the acclaimed Superman (1978), for which he won a BAFTA Award. Reeve appeared in other critically acclaimed films such as The Bostonians (1984), Street Smart (1987) and The Remains of the Day (1993).

Christopher Reeve was born on September 25, 1952, in New York City, the son of Barbara Pitney (Lamb) (1929-2000), a journalist, and Franklin D'Olier Reeve (1928-2013), a teacher, novelist, poet, and scholar. Reeve was of almost entirely English ancestry, with many family lines that had been in America since the early 1600s. His paternal grandfather, Colonel Richard Henry Reeve, had been the CEO of Prudential Financial (when it was called Prudential Life Insurance Company) for over 25 years.  Reeve's father was a Princeton University graduate studying for a master's degree in Russian at Columbia University prior to the birth of his son, Christopher. Despite being born wealthy, Franklin Reeve spent summers working at the docks with longshoremen. Reeve's mother had been a student at Vassar College but transferred to Barnard College to be closer to Franklin, whom she had met through a family connection. They had another son, Benjamin, born on October 6, 1953.  Franklin and Barbara divorced in 1956, and she moved with her two sons to Princeton, New Jersey, where they attended Nassau Street School. Later that year, Franklin Reeve married Helen Schmidinger, a Columbia University graduate student. Barbara Pitney Lamb married Tristam B. Johnson, a stockbroker, in 1959. Johnson enrolled Christopher and his brother, Benjamin, in Princeton Country Day School, which later merged with Miss Fine's School for Girls to become the co-educational Princeton Day School. Reeve excelled academically, athletically, and onstage; he was on the honor roll and played soccer, baseball, tennis, and hockey. The sportsmanship award at Princeton Day School's invitational hockey tournament was named in Reeve's honor. Reeve admitted that he put pressure on himself to act older than he actually was in order to gain his father's approval.  Reeve found his passion in 1962 at age nine when he was cast in an amateur version of the operetta The Yeomen of the Guard; it was the first of many student plays. In mid-1968, at age fifteen, Reeve was accepted as an apprentice at the Williamstown Theatre Festival in Williamstown, Massachusetts. The other apprentices were mostly college students, but Reeve's older appearance and maturity helped him fit in with the others. In a workshop, he played a scene from A View from the Bridge that was chosen to be presented in front of an audience. After the performance, actress Olympia Dukakis said to him, "I'm surprised. You've got a lot of talent. Don't mess it up." The next summer, Reeve was hired at the Harvard Summer Repertory Theater Company in Cambridge for $44 per week. He played a Russian sailor in The Hostage and Belyayev in A Month in the Country. Famed theater critic Elliot Norton called his performance as Belyayev "startlingly effective." The 23-year-old lead actress in the play, a Carnegie Mellon graduate, turned out to be Reeve's first romance. She was engaged to a fellow Carnegie Mellon graduate at the time; they mutually ended the relationship when he made a surprise visit to her dorm room at seven in the morning and found Reeve with her. Reeve's romance with the actress fizzled a few months later when the age difference became an issue. Reeve was briefly involved with Scientology but opted out of becoming a member. He subsequently voiced criticism of the organization.
