IBM Diagramming Template

Flowchart StencilModel 25-5801.
Issue: Made by IBM in the United Kingdom
Date: Between 1960 and 1965.

This stencil is for drawing flowcharts, which allow one to visualise the logical structure of an algorithm. The stencil helped to standardise IBM’s systems analysis methods.  

Flowcharts were introduced as a tool to plan programs in an influential report by Hermann Goldstine and John von Neumann in 1947. Subsequently, various international standards were established.

Flowcharts are one of many forms of diagrams that have evolved to describe programs and, more generally, processes of many different kinds. The diagrammatic method seems to been applied first to processes by Frank Bunker Gilbreth and Lillian Moller Gilbreth in 1921.
