Abstract
As part of the 70th birthday celebration of our dear friend Mario Greco, a brief history of the development of radiative effects at Frascati in QED and QCD covering the period between late sixties to the late eighties is presented. During these two decades, two parallel resummation schemes for QED were formulated and radiative corrections were made for the J/Ψ production and later for Z0 production. The schemes were then extended to QCD to obtain realistic estimates of the e+e− hadronic cross-sections at all energies. It led to the introduction of several new concepts: frozen αs and later to singular αs and to the notion of the maximum value of transverse energy allowed in a radiative process. Some other fall outs from this research such as transverse momentum distributions and hadronic total crosssections which are valid even now would be briefly touched upon.
