Jacques Loeb was the first to induce this artificially in 1900, but the phenomenon had been discovered by Charles Bonnet in 1745 while he was studying the habits of aphids.  Gregory Pincus, in experiments on rabbit fertility in 1963, was the first to produce this effect in mammals.  It occurs in whiptail lizards, though they still display courtship behavior among all females, and it is most notably demonstrated by the birth of male hymenopterans.   Recently produced in mice by mutating one egg to simulate a sperm for another, FTP name this form of asexual reproduction in which an egg develops without fertilization.
