John M. Middleton was a member of the team assembled in 1969 to design the [Prosecutor's Management Information System](/programs/promis/), working under co-directors [Joan E. Jacoby](/people/joan-e-jacoby/) and [Charles R. Work](/people/charles-r-work/) with project manager [Bill Hamilton](/people/bill-hamilton/) at [Peat, Marwick, Mitchell & Co](/organizations/peat-marwick-mitchell-co/).[^1]

His subsequent career has proven difficult to trace. John M. Middleton is a sufficiently common name that multiple individuals matching basic biographical parameters appear in government, STEM, and legal records from the 1960s through the 1990s, making positive identification of the PROMIS team member in later documents uncertain without additional corroborating details.
