After retirement, Lundquist devoted his time to collecting and documenting early space program history, particularly that surrounding German rocket scientists in Huntsville, Alabama.

He completed high school early, in the summer of 1945, in order to enlist in the United States military but changed course after the end of World War II.

[1] In 1947, during his time in university, Lundquist first saw the Wernher von Braun rocket team's work at an American Association for the Advancement of Science annual meeting in Chicago.

[4] As director, Lundquist grew increasingly disappointed with what he saw as NASA's tendency to, rather than evolve old projects, scrap them and begin new one from scratch,[4] and he ultimately retired from the MSFC in 1981.

[2] He contributed a large amount of physical research and documents to the school's Salmon Library and Archives; he also recorded a series of oral interviews with early American and German rocket scientists.
