  The JADE experiment was one of five large detector systems taking data at the
electron-positron collider PETRA, from 1979 to 1986, at $e^+e^-$ annihilation
centre-of-mass energies from 12 to 46.7 GeV. The forming of the JADE
collaboration, the construction of the apparatus, the most prominent physics
highlights, and the post-mortem resurrection and preservation of JADE's data
and software are reviewed.
