This paper intends to tell the story of Modelica (
www.Modelica.org) from the author’s perspective. It is a fantastic saga that for me started in April 1976. The saga includes studying the needs; the original idea; the development of a solution; waiting for mature hardware technology; a start-up company; a fantastic collaboration; an automotive company caring for its software supplier; how to get momentum by standards collaboration; forming the right team; and the magic phone call from the right company.
