Jack Kinzler (January 9, 1920 – March 4, 2014) was a NASA engineer, the former chief of the Technical Services Center at NASA's Lyndon B. Johnson Space Center, known within the agency as Mr. Fix It. He was awarded the NASA Distinguished Service Medal for creating the solar shield that saved Skylab after the original micrometeoroid shield was lost during launch of the station. His other contributions included the flagstaff and plaques used on the Moon for each of the Apollo program Moon landings and the special six iron golf club head with which Apollo 14 astronaut Alan Shepard made his two famous golf drives on the Moon. Early life and NASA career Kinzler was born in Pittsburgh, the son of a photoengraver and inventor who patented several photoengraving devices. As a young man, Kinzler built model planes and flew them in competitions, turning down a scholarship at Pittsburgh's Duquesne University to pursue his interest in aeronautics. He parlayed his model-building skills into a job with National Advisory Committee for Aeronautics building models for wind tunnel testing. When the committee became the core of the newly created National Aeronautics and Space Administration in 1958, Kinzler stayed on. He established the Technical Services Division at the Johnson Space Center in Houston, which included approximately 180 technicians skilled in the various tasks required by the space program, including machining and sheet metal work, welding, electronics, modeling, plastics, and electroplating, along with a field test branch. Kinzler led the Division from 1961 until his retirement in 1977. Apollo program contributions Asked by NASA officials for ideas about how to make a commemorative U.S. flag "fly" on the airless Moon for the planned Apollo landings, it was Kinzler who invented and oversaw the design and implementation of the system ultimately used. As the Moon had no atmosphere that would allow a flag to fly on a traditional flagstaff, NASA had originally planned only to imprint a flag on the lower section of the Apollo Lunar Module, which would be left behind on the Moon as the astronauts returned to the Apollo Command/Service Module to journey back to Earth. Kinzler suggested the Lunar Flag Assembly (LFA), a telescoping pole with a horizontal crossbar that would fit inside a hemmed pocket at the top of the flag, making it visible, as if extended in a strong wind.
