When the Revised Standard Version of the Bible released in the 1950s, computer geniuses streamlined a way to document its changes, starting with the text's "concordance."

A concordance is an alphabetical index of every key word in a given book, with each word’s location and context within the text.

Accurately compiling a concordance is a tremendously labor-intensive project, and has historically only been done for the most important documents. It took James Strong 30 years to assemble one for the King James Bible, a task he completed in 1894.

Rev. John W. Ellison, a mathematics enthusiast, realized a computer might be able to accomplish such a project in a fraction of the time. He proposed the idea to the Remington Rand company.

The company agreed to tackle the concordance with a computer called Univac, and selected John Graham and Al Bosgang to program it.
