-The first ProgrammingLanguage with a context-free grammar (BackusNaurForm was invented to describe it).
It was a simple [Pascal]-like language (actually, the predecessor to Pascal) meant for expressing mathematical algorithms. The uglier language [Fortran] was already being used for this, and had the support of [IBM], so Algol 60 never really took off. Many [

extensions of Algol were created in the 60's
, notably by Burroughs Corporation, which no longer exists. [C] now fills that role.
