 In this paper, Gamow determined the density of the relict background radiation, from which a present temperature of 7°K was predicted – a value which was slightly more than twice the presently-accepted value.In 1967, he published reminiscences and recapitulation of his own work as well as the work of Alpher and Robert Herman (both with Gamow and also independently of him).This was prompted by the discovery of the cosmic background radiation by Penzias and Wilson in 1965; Gamow, Alpher, and Herman felt that they did not receive the credit they deserved for their theoretical predictions of its existence and source.
