Using spectroscopy from the Large Binocular Telescope and imaging from the Hubble Space Telescope we discovered the first strong galaxy lens at zlens > 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 × 1010 M☉, with an upper limit on the dark matter fraction of 60%. The highly magnified (40×) source galaxy has a very small stellar mass (∼108 M☉) and shows an extremely strong [O iii]5007 Å emission line (EW0 ∼ 1000 Å) bolstering the evidence that intense starbursts among very low-mass galaxies are common at high redshift.
