is a family of [https://en.wikipedia.org/wiki/Imperative_programming imperative] computer programming languages developed jointly by a committee of European and American computer scientists in a meeting in 1958 at [[ETH Zurich]] ([https://en.wikipedia.org/wiki/ALGOL_58 Algol 58]).

Algol 58 introduced code blocks and the begin and end pairs for delimiting them. Two years later, [https://en.wikipedia.org/wiki/ALGOL_60 Algol 60] was specified, as the result of a meeting in Paris in January 1960 by 13 European and American scientists, [https://en.wikipedia.org/wiki/Peter_Naur Peter Naur], [https://en.wikipedia.org/wiki/John_Backus John Backus], [[John McCarthy]], [[Mathematician#Bauer|Friedrich L. Bauer]], [[Mathematician#AvWijngaarden|Adriaan van Wijngaarden]], et al. Algol 60 became the standard for the publication of algorithms and had a profound effect on future language development, it was the first language implementing [https://en.wikipedia.org/wiki/Nested_function nested function] definitions with [https://en.wikipedia.org/wiki/Lexical_scope#Static_versus_dynamic_scoping lexical scope].
