I will give a brief description of the Standard Model of the Electroweak interactions and introduce the mechanism of the Electroweak Symmetry Breaking, which gives rise to the prediction of the existence of a scalar boson, the Higgs-Englert boson. The highlights of the search, the discovery and the measurement of the properties of the Higgs boson by the ATLAS experiment will be presented, together with an outlook on the implications of the discovery and future prospects.
