"Ada, language for a complex world" is the title of a (german) tutorial. One could also say "a complex language for a complex world", since Ada is a big, complex language containing a wealth of features.
Ada is the only language in this book that is the result of a contest. This contest was initiated by the DoD in 1975 to find the new programming language for mission critical systems (in particular real-time and embedded systems). The winner, designed by Honeywell-Bull, was named Ada after the world's first programmer, Lady Ada Lovelace, the assistant of Charles Baggabe. The first standard came out in 1983 (Ada83), and a significant extension including object-oriented features in 1995 (Ada95).
