Smalltalk

An Object-oriented, dynamically typed programming language that was the main development language of IBM application and development software from the late 1980's into the late 90's when Java took over. It is a development of Simula but features a dynamic typing system unlike its Algol brethren and that has long been its Achilles heel, it has never been even remotely close to other languages in the Algol family when it comes to speed.
