1. At the NBRF Ledley pursued several major projects: the early 1960s development of the Film Input to Digital Automatic Computer, which automated the analysis of chromosomes; the invention of the Automatic Computerized Transverse Axial whole-body CT scanner in the mid-1970s; managing the Atlas of Protein Sequence and Structure ; and the establishment of the Protein Information Resource in 1984.
Robert Ledley served as editor of several major peer-reviewed biomedical journals.

In 1950, shortly after the outbreak of the Korean War, Robert Ledley was contacted by a US Army recruitment officer, who offered him a choice: he could volunteer to join the US Army Dental Corps as a first lieutenant or be conscripted into the infantry as a private.
Robert Ledley promptly volunteered, and was sent to the US Army Medical Field Service School for training.
Robert Ledley started to use SEAC himself for his dental research, but after proving an adept programmer and troubleshooter, he found himself working with SEAC full-time on a wide variety of projects, including a remote-controlled aircraft guidance system.
For Robert Ledley, working with SEAC produced an epiphany, concerning both his career and the potential importance of computers to biomedical research.
At the National Bureau of Standards, Robert Ledley's work was primarily related to solving military problems using the techniques of operations research.
When Robert Ledley lost his job at the NBS in 1954 due to budget cuts, he turned down an offer to work for IBM.
In 1954, Gamow invited Robert Ledley to join the elite RNA Tie Club; some other members of the club were Watson, Crick, Richard Feynman, Max Delbruck, Edward Teller, and Sydney Brenner.
Robert Ledley's main work for the RNA Tie Club was an effort to generate a set of contingency tables for the purpose of writing a computer program that would determine the correspondence between any three-letter sequence of nucleotide bases and any amino acid.
In 1956, Robert Ledley was hired as an assistant professor of electrical engineering at the George Washington University School of Engineering and Applied Science.
Robert Ledley and Lusted expressed hope that by harnessing computers, much of physicians' work would become automated and that many human errors could therefore be avoided.
In early 1957, Robert Ledley was hired on a part-time basis by the National Academy of Sciences - National Research Council to conduct a national survey of current and potential computer use in biology and medicine in the United States.
Robert Ledley designed FIDAC to scan photomicrographs of chromosomes in order to automate the labor-intensive task of karyotype analysis, which is used to detect conditions such as Turner syndrome and Down syndrome.
Robert Ledley is most widely known for his 1970s efforts to develop computerized tomography or CAT scanners.
Quickly trying to raise enough funds to cover the NBRF employee salaries, Robert Ledley looked for projects the organization could undertake for Georgetown University.
In 1974, after several months of working with Georgetown's machinists and auto body specialists at a nearby Cadillac dealer, Robert Ledley's team completed construction of the Automatic Computerized Transverse Axial scanner.
News of this and other similar cases spread quickly and Robert Ledley soon faced worldwide demand for machines like ACTA.
Robert Ledley established Digital Information Science Corporation in 1974, which sold the ACTA scanners for $300,000 each.
On November 25,1975, Robert Ledley was issued the patent for the design of ACTA.
