The credit for coming up with the basic idea goes not to Grace Hopper, although she contributed to the language and promoted it, but to Mary Hawes. She was a Burroughs Corporation programmer who saw a need for a computer language. In March 1959, Hawes proposed that a new computer language be created. It would have an English-like vocabulary that could be used across different computers to perform basic business tasks.
By that September , COBOL's basic syntax was nailed down, and COBOL programs were running by the summer of 1960. In December 1960, COBOL programs proved to be truly interoperable by running on computers from two different vendors. COBOL was on its way to becoming the first truly commercial programming language.
It would still be the business language of choice until well into the 1980s. And it's not done yet.
