===Background=== In the late 1950s, computer users and manufacturers were becoming concerned about the rising cost of programming. A 1959 survey had found that in any data processing installation, the programming cost US$800,000 on average and that translating programs to run on new hardware would cost US$600,000. At a time when new [[Timeline of programming languages|programming languages were proliferating]], the same survey suggested that if a common business-oriented language were used, conversion would be far cheaper and faster.{{sfn|Beyer|2009|p=282}} On 8 April 1959, [[Mary K. Hawes]], a computer scientist at [[Burroughs Corporation]], called a meeting of representatives from academia, computer users, and manufacturers at the [[University of Pennsylvania]] to organize a formal meeting on common business languages.<ref>{{Cite journal|last=GΓΌrer|first=Denise|date=1 June 2002|title=Pioneering Women in Computer Science|journal=SIGCSE Bull.|volume=34|issue=2|pages=175β180 |doi=10.1145/543812.543853 |s2cid=2577644|issn=0097-8418}}</ref> Representatives included [[Grace Hopper]] (inventor of the English-like data processing language [[FLOW-MATIC]]), [[Jean Sammet]], and [[Saul Gorn]].{{sfn|Beyer|2009|pp=281β282}}{{sfn|Sammet|1978a|p=200}} At the April meeting, the group asked the [[United States Department of Defense|Department of Defense]] (DoD) to sponsor an effort to create a common business language. The delegation impressed Charles A.

She said β after hearing the rumors β one of her collaborators went out and bought a granite tombstone. "He had the word COBOL cut in the front of it. Then he shipped it express collect to Mr. Phillips in the pentagon." The prank on Charles Phillips, a leader for the project at the defense department, got the attention of the powers that be and was a turning point she said. COBOL would go on to become the most widely used and longest lasting computer languages in history. | archive-url = https://web.archive.org/web/20190524035248/https://www.tpr.org/post/how-cobol-still-powers-global-economy-60-years-old | archive-date = 24 May 2019 | df = dmy-all }}</ref> who thought that they "thoroughly understood" the DoD's problems. The DoD operated 225 computers, had 175 more on order, and had spent over $200 million on implementing programs to run on them. Portable programs would save time, reduce costs, and ease modernization.{{sfn|Beyer|2009|p=283}} Charles Phillips agreed to sponsor the meeting, and tasked the delegation with drafting the agenda.{{sfn|Beyer|2009|p=284}}
