Don't forget IBM
Authored by: Anonymous on Sunday, May 06 2012 @ 06:21 PM EDT
It was developed by an Ottawa company called Object Technology
International, a wholly-owned subsidiary of IBM at that time, that made the
Envy Smalltalk products (and the core of IBM's VisualAge for Smalltalk
product). They then made VisualAge for Java, which was mostly written in
Smalltalk and used a hybrid VM that could run both Smalltalk and Java
bytecodes.

The same VM team later made the J9 Java VM that ran on many different
CPU architectures and scaled from wimpy embedded boards up to giant
mainframes. They also made a cleanroom implementation of the Java
class libraries that was bug-for-bug compatible with Sun's. Most of the
cleanroom class library development was done by 2 people, who were
both superstars (I remember estimating that they were forty times as
productive as their counterparts at Sun).

Just down the hall from those guys, were the people who developed the
SWT widget toolkit. In the same building were most of the people who
wrote the Eclipse open-source IDE (who of course had lots of IDE-
building experience from working on Envy Smalltalk, VA Smalltalk, VA
Micro Edition and VA Java). Nowadays the whole thing is just another part
of IBM, but most of those great people are still there.
