Mr. Floyd Weakley reported to NSA in 1965 as a mathematician in a development program for new cryptanalysts.

By the 1980s, he was leading a team of analysts in the study of a state-of-the-art cryptosystem used by several major adversaries of the United States. His understanding of the technology involved was a major factor in the team's success.

In analyzing another advanced cryptosystem, Mr. Weakley identified several unusual systemic aspects and devised appropriate cryptanalytic test procedures, one of which was named for him.

While working as an analyst and leader of analysts, Mr. Weakley authored or co-authored twenty-three technical papers. He also was instrumental in establishing a career development program for cryptanalysts.

Mr. Weakley had a profound effect on NSA's hiring of minorities and their career development. As a member of many boards and in his role as a technical director, he fostered new approaches to diversity issues. In recognition of these efforts, the NAACP presented Floyd Weakley with the Roy Wilkins Renowned Service Award at their national convention in 1996.

One who was influenced by him wrote: "Floyd Weakley left behind a career of footprints which are daunting for any single person to fill."
