The Long Journey to the Discovery of the Higgs Boson

**Selected historical flashbacks to hadron collider experiments on the way to the energy frontier** **Abstract:** This history talk recalls some selected stages and milestones of experiments at energy frontier hadron colliders, leading to the LHC project and the Higgs boson discovery of ATLAS and CMS. This journey started more than 50 years ago with CERN’s Intersecting Storage Rings ISR. For the LHC experiments ATLAS and CMS, and in particular for ATLAS as a showcase, some stages of the pre-history as well as the challenging path to the approval, financing, and construction will be mentioned.
