The first time one of us (G.P.) encountered Earle was in Summer 1966, when
she was directed to study Earle's papers on radiative corrections to
quasi-elastic electron scattering. The suggestion had come from Bruno Touschek,
at the time head of the theoretical physics group at the Frascati National
Laboratories near Rome. About the same time, Earle came from MIT to visit
University of Rome and Frascati. G.P. was a young post-graduate, who had
studied Earle's papers and was awed by his already impressive scientific
figure. After almost 40 years had passed, Earle visited Italy with his wife
Ruth, making Frascati their base for an extended visit of almost a month. They
were housed in what was then the laboratory hostel for foreign visitors, a
small villa higher up above the hill, toward the town of Frascati. Since then,
we became close friends, a friendship which included both his family and ours,
and which has been very important for us. In memory of that first visit and in
gratitude for the many years of friendship, we will tell here a story of
infrared radiative corrections to charged particle scattering, to which Earle's
papers gave an important contribution.
