Worldwide particle physics in the year 2010 was marked by the very successful first run of the Large Hadron Collider (LHC) at 7 TeV, the highest energy ever reached at a collider. From the first proton-proton collisions at this energy on 30 March to the successful run with lead ions until the technical stop in December, the whole year showed a constantly improving, excellent performance of the LHC machine and detectors, exceeding even the most optimistic expectations. This led to first-class physics results and publications. We are very proud that many people from DESY contributed to this success story of the LHC. The DESY contributions include technical support for the detectors, providing an excellent computing infrastructure, the calibration of detector components and carrying out data analyses
