Unidentified man with instrument
- After 1949 – before 1976
A black and white photograph of an unidentified man standing next to an IBM 407 Accounting Machine. Introduced in 1949, the IBM 407 was one of a long line of IBM tabulating machines. The 407 read punched cards, totaled fields on the cards, made simple decisions, printed results, and, with the aid of a summary punch, output results on punched cards that could be input to other processing steps.
