String from Veneziano model

This article is about my memories from the discovery[1, 2, 3, 4] that the Veneziano model[5] described in fact interacting strings. I came to the understanding that the dual or Veneziano model is really a model of strings independently of Susskind[3] and Nambu[4]. A characteristic feature of my approach [1, 2] 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 lead to planar diagrams dominating when only neighbours on the chain interact significantly. The article also mentions the works of Ziro Koba’s and mine[10, 12, 13] about extending the Veneziano model first to five external particles as Bardakci and Ruegg[6], Chan Tsou[8] and Goebel and Sakita[9] also did and subsequently to an arbitrary number n of external mesons.
