Around SuSy 1970
This is the talk given at the Symposium "Thirty Years of Supersymmetry", October 13-15, 2000, Theoretical Physics Institute, University of Minnesota. The history of construction of the first supersymmetric field theory in four dimensions (1970) is reviewed. In Appendix a verbatim translation of my paper published in 1971 in Russian (preprint FIAN-41) is presented. In this paper what is now known as chiral and vector supermultiplets were algebraically constructed.
