The Veneziano formula was quickly generalized to an equally consistent N-particle amplitude[1] for which Yoichiro Nambu,[2] Holger Bech Nielsen,[3] and Leonard Susskind[4] provided a physical interpretation in terms of an infinite number of simple harmonic oscillators describing the motion of an extended one-dimensional string, hence came the name "string theory."
The study of dual resonance models was a relatively popular subject of study between 1968 and 1973.[5] It was even taught briefly as a graduate level course at MIT, by Sergio Fubini and Veneziano, who co-authored an early article.[6] It fell rapidly out of favor around 1973 when quantum chromodynamics became the main focus of theoretical research[7] (mainly due to the theoretical appeal of its asymptotic freedom).[8]
