Chart 40: The Administrative Line

This chart is a graphic representation of the growth of the function from literally a one person shop to the highly technical, highly specialized function that administration has become. It also shows those areas of administration that Directors felt were personally important to them. The continuity is also interesting. Hillory Tolson was responsible for the function more than 25 years from 1933 until he retired, with the exception of a short period when he was the Regional Director in Santa Fe, New Mexico.
