Seymour Berry was born and raised in New York City. Not long after completing high school, he began a plate printer apprenticeship with the Bureau of Engraving and Printing in 1942. Within a short time, however, Berry went into the Army and served as an infantryman in Europe during World War II. After the war, he resumed his apprenticeship at the BEP in 1946. Additionally he attended The George Washington University in Washington, DC, and eventually received a law degree. Berry worked his way up in the organization, becoming a plate printing foreman, Superintendent of the Examining Division, Chief of the Office of Securities Processing, and Assistant Director for Administration before being named BEP Director in 1977. He retired from government service in 1979 after serving over 33 years in the Bureau of Engraving and Printing. He died in 2008 at the age of 86.
