REVEALING THE PATH TO THE SUPERWORLD
This is a revised version of the article prepared by M. Marinov for the Yuri Golfand Memorial Volume The Many Faces of the Superworld, (World Scientific, Singapore, 2000), page 32. M. Marinov worked on it in the summer of 1999, and then started revising it to include a part devoted to supergravity. The work was not completed: he died of cancer on January 17, 2000.
A brief history of ideas which paved the way to supersymmetry is presented.
