About Marion Lee Johnson
From 1967 to 1969, Johnson worked as a mathematician with Boeing, a leader in the building of the Saturn V rocket used to launch each Apollo mission. She worked on the Apollo program at NASA’s Marshall Space Flight Center under the direction of brilliant, but complicated, rocket designer Wernher von Braun.
As part of the team, Johnson was responsible for calculations to simulate vehicle piece impact trajectories. She recorded an incredible perfect score over her 20 successful missions and was included in the Apollo/Saturn V Roll of Honor.
Following her two-year contract with Boeing and NASA, Johnson spent 26 years at Pfizer, Inc. as a project leader and was later a computer networking and security instructor at Branford Hall Career Institute.
