Peter Breckheimer came to the lab in 1966 and retired in 2006 after 39 years of service. The majority of these records date from the period of his employment. He was hired into Section 314, and stayed until a reorganization of the Systems division (310) in 1995. Coincidentally 1966 is the same year the division personnel charts begin. Section 314 was the Scientific Programming section for three years, in 1969 it became the Computation and Analysis section. From 1977 until 1995, past the period of these records, section 314 was the Navigations Systems section. Breckheimer was listed a supervisor on the personnel charts starting in 1977. A 1993 chart identifies the groups and Breckheimer was listed as the supervisor of group 3149, Navigation Software Development. After the reorganization in 1995 and Section 314 became the Ground Systems section and Section 312 became the Navigation and Flight Mechanics section. At this point Breckheimer moved to 312 but remained the supervisor of Navigation Software Development. This history of the names of section 314 helps explain the concentration on software development items in the collection.
