INFN has a long-standing tradition in the use of synchrotron radiation and in the construction of accelerators dedicated to its use. The tradition started with the use of the ADONE 1.5 GeV electron storage ring up to 1993 and continued with the DAFNE electron-positron 0.5 GeV collider. INFN is now developing at Frascati a new user facility EuPRAXIA@SPARC_Lab based on plasma acceleration. This new facility in the framework of the EuPRAXIA EU project should produce FEL radiation beams for a wide range of applications.
During this workshop the story of synchrotron radiation at Frascati from its early beginnings (e-synchrotron) up to nowadays will be reported with talks related to the past and to all the people who made it possible, to the present and to the future scientific activities.
