Introduction to Deep Inelastic Scattering: Past and Present.

Joel Feltesse
brief history of Deep Inelastic Scattering (DIS) physics is presented. Going from the glorious years at SLAC 45 years ago, through the high statistics fixed experiments in the eighties and the discoveries at HERA since twenty years, without omitting Polarised Deep Inelastic Scattering, until the most recent open problems in DIS.
