The development from a test facility for the TESLA project of a Linear Collider with Integrated X-ray Free-Electron Laser to the world's first soft X-ray FEL user facility is described. In the wavelength range from 6.5 to 60 nm FLASH provides short pulses (~25 fsec) containing ~10 12 photons in laterally coherent beams with brilliance about 9 orders of magnitudes higher than achieved at the best synchrotron radiation storage ring facilities today. FLASH opened a new area in photon science where matter in non equilibrium states is studied with atomic resolution in space and time.
