What was the name of the person that created Open Type Format?
OpenType evolved from TrueType orignally developed by Apple in the late eighties, it contains input from various Apple, Microsoft and Adobe people. It has no single 'creator'.
But someone has to have developed the techical solution we use today?
You may have heard the phrase "A camel is a horse designed by a committee." Perhaps that sentiment can be applied to OpenType as well. Within the overall standard exists the work of a great number of engineers, ratified by businessmen. The fact that both TT and CFF outlines are supported is one area, but there are many others.
