1. Giorgio and CDF Celebrating 70 years of Giorgio and >25 years of CDF Henry Frisch Univ. of Chicago

2. A Personal Note: I first met Giorgio at the 1974 London Conf- we had just found ‘direct muons’ (charm): He came to the session in tennis whites + rackets, with charm and enthusiasm. “The lack of Pt ‘bumps’ means that there are no significant heavy objects (M from 3 to 10 GeV) that decay into 2 leptons”-Leon

3. Intro: Giorgio’s Physics Interests: See Fermi’s Yale Lectures of 1951 “Electromagnetic and Yukawa Interaction Constants:” “Perhaps future developments..will enable us to understand the reasons for the existence and the strength of the various interactions.”- Fermi

4. The Start of CDF Jan 1997- Cronin heads Colliding Beam Dept.- - 2 Init. Designs: one magnetic, one not Wilson decrees 10M$ cap on detector cost (!) Oct. 78- Wilson resigns- Lederman new Dir. Oct. 79- CDF Dept formed; Alvin Head of CDF Giorgio had already approached Alvin – Pisa is one of the founding institutions at formal start. Fig. from TDR 1981 N.B.
