Algol 68 was a bit before my time, but c.1980 we did learn Algol W at Bristol Uni., which was Niklaus Wirth's idea of what Algol 68 should have been, and a predeceesor to Pascal, Modula-2, etc.
One thing I always liked about some older languages was being able to have blanks in identifiers. Although I see that they actually managed to invent a new stropping variant that doesn't work with that… For the "kids"…
