ALGOL

ALGOL (short for ALGOrithmic Language) is a family of imperative computer programming languages originally developed in the mid-1950s which greatly influenced many other languages.

Quotes

 * Although my own previous enthusiasm has been for syntactically rich languages like the Algol family, I now see clearly and concretely the force of Minsky's 1970 Turing lecture, in which he argued that Lisp's uniformity of structure and power of self reference gave the programmer capabilities whose content was well worth the sacrifice of visual form.

 * One of the most important and fascinating of all computer languages is Lisp (standing for "List Processing"), which was invented by John McCarthy around the time Algol was invented.

 * [ALGOL 60] is a language so far ahead of its time, that it was not only an improvement on its predecessors, but also on nearly all its successors.

 * [ALGOL W] was not only a worthy successor of ALGOL 60, it was even a worthy predecessor of PASCAL.

 * The ALGOL compiler was probably one of the nicest pieces of code to come out at that time. I spent hours trying to fix and change the compiler. Working with it so closely affected the way I think about programming and had a profound influence on my style.
 * Gary Kildall (1986) Programmers at Work.


 * There is an appreciated substance to the phrase "ALGOL-like" which is often used in arguments about programming, languages and computation. ALGOL appears to be a durable model, and even flourishes under surgery — be it explorative, plastic, or amputative.
