Ada Programming Language
The Ada Programming Language was created for embedded machines. It was part of a very long and extensive language design effort. It was finished in February 1980 and the specs were then frozen. Ada is in use by many prominent organizations, such as the depart of defense. It is also used with Computer Aided Design and banking systems.
