Ms. Lillie Berry began her career at Arlington Hall in 1956 as a clerk typist in the signals analysis unit. She quickly learned the terminology and pressed analysts to explain to her the concepts. After attending a signals analysis course and mastering a basic understanding of the subject, she was requested, in the early 1960s, to teach portions of the introductory material. She, thus, became the first African American woman in the Agency to give instruction in that discipline. In 1968, she marked another first when she became the first African American woman assigned as an Agency recruiter. Finally, Ms. Berry is remembered for having established the Career Information Center, the predecessor of today's Career Resource Center. Ms. Berry retired in 1988.
