String from Veneziano model

This article is about my memories from the discovery that the Veneziano model describes in fact interacting strings. I came to the understanding of that the dual or Veneziano model is really a model of strings independently of L. Susskind and Y. Nambu. A characteristic feature of my approach was that I used thinking of very high order “fishnet” or planar Feynman diagrams as the way of at first describing the development of the strings. A chain of constituents leads to planar diagrams dominating when only neighbours on the chain interact significantly. The article also mentions the works of Ziro Koba and mine about extending the Veneziano model first to five external particles - as Bardakci and Ruegg, Chan Tsou, and Goebel and Sakita also did - and subsequently to an arbitrary number n of external mesons.
