Question: What was the job title of this American engineer and former astronaut aboard Apollo 11, who inspired the musical Moon Landing?
Context: Buzz Aldrin (born Edwin Eugene Aldrin Jr.; January 20, 1930) is an American engineer and former astronaut.  As the Lunar Module Pilot on Apollo 11, he was one of the first two humans to land on the Moon, and the second person to walk on it.  He set foot on the Moon at 03:15:16 on July 21, 1969 (UTC), following mission commander Neil Armstrong.  He is a former U.S. Air Force officer with the Command Pilot rating.  He also went into orbit on the Gemini 12 mission, finally achieving the goals for EVA (space-walk work) that paved the way to the Moon and success for the Gemini program; he spent over five hours on EVA on that mission. Stainless steel commemorative plaques measuring 9 by were attached to the ladders on the descent stages of the United States Apollo Lunar Modules flown on lunar landing missions Apollo 11 through Apollo 17, to be left permanently on the lunar surface.  The plaques were originally suggested and designed by NASA's head of technical services Jack Kinzler, who oversaw their production.  All of the plaques bear facsimiles of the participating astronauts' signatures.  For this reason, an extra plaque had to be made for Apollo 13 due to the late replacement of one crewmember.  The first (Apollo 11) and last (Apollo 17) plaques bear a facsimile of the signature of Richard Nixon, President of the United States during the landings, along with references to the start and "completion" of "man's" "first" explorations of the Moon and expressions of peace for "all mankind".  All, except the Apollo 12 plaque (which is also textured differently), bear pictures of the two hemispheres of Earth.  Apollo 17's plaque bears a depiction of the lunar globe in addition to the Earth.  The plaques used on missions 13 through 16 bear the call-sign of each mission's Lunar Module.  All the plaques were left on the Moon, except the two for the aborted Apollo 13 which did not land on the Moon. Apollo 13 is a 1995 American space adventure docudrama film directed by Ron Howard and starring Tom Hanks, Kevin Bacon, Bill Paxton, Gary Sinise, and Ed Harris.  The screenplay by William Broyles, Jr. and Al Reinert, that dramatizes the aborted 1970 Apollo 13 lunar mission, is an adaptation of the book "Lost Moon: The Perilous Voyage of Apollo 13" by astronaut Jim Lovell and Jeffrey Kluger.  The film depicts astronauts Lovell, Jack Swigert, and Fred Haise aboard Apollo 13 for America's third Moon landing mission.  En route, an on-board explosion deprives their spacecraft of most of its oxygen supply and electric power, forcing NASA's flight controllers to abort the Moon landing, and turning the mission into a struggle to get the three men home safely. Several planned missions of the Apollo manned Moon landing program of the 1960s and 1970s were canceled for a variety of reasons, including changes in technical direction, the Apollo 1 fire, hardware delays, and budget limitations.  Immediately after the program achieved its primary objective in July 1969 with Apollo 11 to land men on the Moon and return them safely, nine more landing missions were planned, but the last three, Apollo 18, 19 and 20, were canceled. "Apollo 21" is an apocryphal reference to an eleventh manned Moon landing mission of NASA's Apollo program.  Apollo contracted for the construction of fifteen Saturn V launch vehicles used to launch the Apollo spacecraft to the Moon, and achieved the first manned landing with the sixth one (Apollo 11), leaving nine for follow-on lunar missions, through Apollo 20.  However, budget cuts caused NASA to cancel the last three missions, ending the lunar program after Apollo 17.  One Saturn V was used to launch the Skylab space station, and parts of the other two became museum displays. Moon Landing is a musical with book, lyrics and music by Stephen Edwards.  The story, from an original idea and synopsis by Justin Fleming, is based on the American Space Race and the Apollo 11 spaceflight which on July 20, 1969 landed the first humans on the Moon and is seen through the eyes of Buzz Aldrin, the second man to walk on the moon. Alan LaVern Bean (born March 15, 1932), (CAPT, USN, Ret.) , is an American former naval officer and Naval Aviator, aeronautical engineer, test pilot, and NASA astronaut; he was the fourth person to walk on the Moon.  He was selected to become an astronaut by NASA in 1963 as part of Astronaut Group 3.  He made his first flight into space aboard Apollo 12, the second manned mission to land on the Moon, at the age of thirty-seven years in November 1969.  He made his second and final flight into space on the Skylab 3 mission in 1973, the second manned mission to the Skylab space station.  After retiring from the United States Navy in 1975 and NASA in 1981, he pursued his interest in painting, depicting various space-related scenes and documenting his own experiences in space as well as that of his fellow Apollo program astronauts. The Soviet crewed lunar programs were a series of unsuccessful programs pursued by the Soviet Union to land a man on the Moon, in competition with the United States Apollo program to achieve the same goal set publicly by President John F. Kennedy on May 25, 1961.  The Soviet government publicly denied participating in such a competition, but secretly pursued two programs in the 1960s: crewed lunar flyby missions using Soyuz 7K-L1 (Zond) spacecraft launched with the Proton-K rocket, and a crewed lunar landing using Soyuz 7K-LOK and LK Lander spacecraft launched with the N1 rocket.  Following the dual American successes of the first crewed lunar orbit on December 24–25, 1968 (Apollo 8) and the first Moon landing on July 20, 1969 (Apollo 11), and a series of catastrophic N1 failures, both Soviet programs were eventually brought to an end.  The Proton-based Zond program was canceled in 1970, and the N1 / L3 program was terminated de facto in 1974 and officially canceled in 1976.  Details of both Soviet programs were kept secret until 1990 when the government allowed them to be published under the policy of "glasnost". First on the Moon: A Voyage with Neil Armstrong, Michael Collins and Edwin E. Aldrin, Jr. (ISBN  ) is a book by the crew of the Apollo 11 Moon landing (Neil Armstrong, Michael Collins, Buzz Aldrin) in collaboration with Gene Farmer and Dora Jane Hamblin, first published in 1970.  It describes the events leading up to and during the Apollo 11 mission, the first manned landing on the Moon.  It was first published in June 1970 by Little, Brown and Company. Apollo 10 was the fourth manned mission in the United States Apollo space program, and the second (after Apollo 8) to orbit the Moon.  Launched on May 18, 1969, it was the F mission: a "dress rehearsal" for the first Moon landing, testing all of the components and procedures, just short of actually landing.  The Lunar Module (LM) followed a descent orbit to within 8.4 nmi of the lunar surface, at the point where powered descent for landing would normally begin.  Its success enabled the first landing to be attempted on the Apollo 11 mission two months later.
