DISCOVERY OF A QUADRUPLE LENS IN CANDELS WITH A RECORD LENS REDSHIFT z=1.53

Using spectroscopy from the Large Binocular Telescope and imaging from the Hubble Space Telescope we discovered the first strong galaxy lens at z(lens) > 1. The lens has a secure photometric redshift of z = 1.53 +/- 0.09 and the source is spectroscopically confirmed at z = 3.417. The Einstein radius (0 ''.35; 3.0 kpc) encloses 7.6 x 10(10) M-circle dot, with an upper limit on the dark matter fraction of 60%. The highly magnified (40x) source galaxy has a very small stellar mass (similar to 10(8) M-circle dot) and shows an extremely strong [O III](5007 angstrom) emission line (EW0 similar to 1000 angstrom) bolstering the evidence that intense starbursts among very low-mass galaxies are common at high redshift.
