We measured the isotope shift of the 1S-2S transition in atomic hydrogen and deuterium to be 670.933plus-or-minus0.056 GHz, using Doppler-free two-photon spectroscopy with a frequency-doubled, pulsed, dye laser. The Balmer-$beta$ line is simultaneously observed in saturated absorption with the fundamental dye-laser output. A comparison of the intervals 1S-2S and 2P$sub 3$$/$$sub 2$-4D$sub 5$$/$$sub 2$ determines the Lamb shift of the 1S ground state to be 8.20plus-or-minus0.10 GHz (H) and 8.25plus-or-minus0.11 GHz (D), in agreement with the theoretical values.
