(n. 23 may. 1925, Montclair, N.J., EE.UU.).

Genetista estadounidense. Obtuvo su Ph.D. en la Universidad Yale. Con su discípulo Norton Zinder, Lederberg descubrió que ciertos virus son capaces de transportar un gen bacteriano de una bacteria a otra. Esto convirtió a las bacterias, tales como la Drosophila y el moho del pan Neurospora, en herramientas importantes para la investigación genética. También desarrolló técnicas de cruzamiento para la genética bacteriana. En 1958 compartió el Premio Nobel con George Wells Beadle y Edward L. Tatum por el descubrimiento de los mecanismos de recombinación genética en bacterias.
