One of NASA's brightest administrators, George Mueller, passed away on Oct. 12, 2015 at the age of 97.
In 1951, Mueller earned his Ph.D in physics from The Ohio State University. While working toward his degree, he served as an assistant professor of electrical engineering. His university research focused on the new field of system engineering as well as dielectric antennas.
Mueller went on to become regarded as the "father of the space shuttle" and helped design Skylab (America's first space station). As head of NASA's Office of Manned Spaceflight, Mueller is generally credited as the person who made landing on the Moon possible in 1969 by meeting President John F. Kennedy's short timeline challenge through bold management.
