The Crab Nebula has become established as the standard candle for TeV gamma-ray astronomy. No evidence for variability has been seen. The spectrum of gamma rays from the Crab Nebula has been measured in the energy range 500 GeV to 8 TeV at the Whipple Observatory. Two methods of analysis involving independent Monte Carlo simulations and two databases of observations (1988{endash}89 and 1995{endash}96) were used and give close agreement. Using the complete spectrum of the Crab Nebula, the spectrum of relativistic electrons is deduced and the spectrum of the resulting inverse Compton gamma-ray emission is in good agreement with the measured spectrum if the ambient magnetic field is {approximately}25{endash}30 nT. {copyright} {ital 1997 American Institute of Physics.}
