Abstract
High energy neutrino physics has been an active field of research at all proton accelerators over the last two decades and has played a key role in the development and verification of the standard model. The author reviews the experimental techniques of neutrino physics, traces the main developments, summarises the present status of the field and gives some hints on future activities. The author concentrates on those fields of physics where neutrino experiments have made unique contributions, namely the structure of the charged and neutral weak currents, the verification of the quark parton model and the determination of the quark and gluon distributions in the nucleon including their scaling violations, and the study of new particle production in neutrino interactions.
