About the Author:

Luisa Bonolis is a Research Scholar at the Max Planck Institute for the History of Science in Berlin. Her work focuses on the development of physical and astrophysical sciences in the twentieth century. She has led several oral history projects and has widely published on topics ranging from the evolution of cosmic-ray studies, of nuclear and particle physics, to the emergence of astroparticle physics and relativistic astrophysics. These subjects are also extensively covered in her most recent book (co-author: Juan Andres Leon) Astrophysics, Astronomy and Space Sciences in the History of the Max Planck Society, Leiden, Brill (in print).

Luciano Maiani, Emeritus Professor at Università di Roma La Sapienza, is author or coauthor of over 200 scientific publications, three books on Elementary Particle Theory (Francis &Taylor) and one on Multiquark Hadrons (Cambridge University Press). With S. L. Glashow and J. Iliopoulos, has predicted the existence of charmed particles as a crucial step towards the formulation of a unified theory of the Electroweak Interactions. Charmed particles have been discovered in 1976 with properties close to those anticipated in the original GIM paper. Socio of Accademia Nazionale dei Lincei, of the Russian Academy of Sciences and Fellow of the American Physical Society, Maiani works at present in the theory of the recently discovered Exotic Hadrons, described as compact multiquark states.

Giulia Pancheri joined Bruno Touschek's group at Frascati National Laboratories in 1966, and worked with him on infrared radiative corrections to electron-positron experiments at ADONE. An active particle physicist in high energy phenomenology, she has been INFN research director in Frascati and coordinator of three EU networks on physics at the Frascati electron-positron collider DAFNE, founding in 1996 the Bruno Touschek Spring School for young researchers. After retirement in 2008, she continued research on models for the total cross section and the role of soft gluon resummation in hadronic processes, while focusing on highlighting Bruno Touschek's scientific accomplishments in the wider context of the birth of collider physics. She is the author of the book "Bruno Touschek's Extraordinary Journey, from death-rays to antimatter", Springer Biographies, 2022. A Fellow of the American Physical Society since 2009, she lives in Rome and is a senior scientist affiliated to the Frascati Laboratories.
