Abstract: The observation of W and Z bosons and a measurement of the production crosssections in proton proton collisions at E CM = 7 TeV are presented using datafrom the ATLAS experiment at the LHC. Results are based on 118 W -> lnu and 125Z-gamma* -> ll l=e,mu candidate events corresponding to an integratedluminosity of about 17 nb^-1 and 225 nb^-1 respectively. The measured values ofsigma W x BRW -> lnu = 9.3 \pm 0.9 stat \pm 0.6 syst \pm 1.0 lumi nband sigma Z-gamma* x BRZ-gamma* -> ll, 66
