description Physics at LEP stopped early on Monday 9 october for a scheduled one-week shutdown. The final days of this run were extremely profitable for the four experiments, with the machine colliding substantial electron and positron beams practically non-stop. The superconducting 'low-beta' magnets to compress the beams and increase the collision rate in the experimental areas made their debut for physics, pushing luminosity levels for the first time above 10 to the 30. The machine also made two systematic sweeps of the energy region around 91 GeV, so that the experiments could make a precision fix on the famous Z resonance. With improvements during the shutdown and with increased expertise from machine development studies, collision rates should continue to improve. Between them, the experiments - ALEPH, OPAL, DELPHI, and L3 - have accumulated more than ten thousand examples of Z particles, and first physics results should soon emerge. ALEPH presented by J. Lefrançois. DELPHI presented by U. Amaldi. L3 presented by S. Ting.
