The following description is taken from the Wikipedia article linked below:
Ada is a structured, statically typed programming language designed by Jean Ichbiah of CII Honeywell Bull in the 1970s. It is positioned to address much the same tasks as C or C++, but with the type-safety of a language like Java. (Some cite Ada as an influence on Java.) Ada was named after Ada, Lady Lovelace, often credited as the first computer programmer.
