The Social Security Administration’s website has a history section. It includes Social Security Number trivia and describes why the geographical assignment of the first three digits of the SSN has an anomaly with New Hampshire having lower numbers than Maine. This was done so that Social Security Board Chairman John G. Winant, who was from New Hampshire, could be assigned 001-01-0001. But he declined it and it was eventually given to Grace D. Owen who was the first to apply for a number in New Hampshire. I also found an interesting photo of female African-American keypunch operators.
