An Object-oriented, dynamically typed programming language that was the main development language used by IBM for the creation of application and development software from the late 1980s into the late 90s when Java took over. It is a simplification of Simula patterned on Euler (experimental Pascal predecessor) but features a dynamic typing system closer to LISP than to most of its Algol brethren and that has long been its Achilles heel, while simplifying programming somewhat it also causes a considerable execution slowdown in comparison to other languages in the Algol family.
The Smalltalk language suffered great setbacks in that latter half of the nineties when almost all of the companies building tools for the language turned their attention to Java and either mothballed or discontinued their Smalltalk offerings wholesale, in more recent years the renewed interest in Eiffel has also contributed to an erosion of the Smalltalk mindshare, but the latter language has an even cleaner object orientation features and greatly improved execution speeds.
