Abstract: One of the original rationales for building JWST was to move beyond the limitations of the Hubble Space Telescope in the search for the first galaxies to form. This search is now yielding fruit as the results of JADES, the JWST Advanced Deep Extragalactic Survey. JADES uses 800 hours of observing time largely from the NIRCam and NIRSpec Instrument Teams. By always using NIRCam in parallel with either NIRSpec or MIRI, the effective data gathering time is doubled. This program has already pushed the redshift limit to z~13.2 with more to come. Spectroscopy has revealed surprises such as a galaxy observed at an age of only 700 million years that has so much carbon that a 2175 Angstrom extinction bump is seen. Other surprises include detection of more z>7 galaxies than predicted and many galaxies with extremely strong emission lines.
