  A review is given of the historical developments of 1982 that lead to the
supergravity unified model (SUGRA)with gravity mediated breaking of
supersymmetry. Further developments and applications of the model in the period
1982-85 are also discussed. The supergravity unified model and its minimal
version (mSUGRA) are currently among the leading candidates for physics beyond
the Standard Model. A brief note on the developments from the present vantage
point is included.
