A Russian author, invariably in collaboration with his son Sergei Abramov (1944- ), who is not always credited.
The novel-length "Hožhdenie za Tri Mira" (1966 Mir priključni: Almanah #12) became the title story for their Journey across Three Worlds: Science Fiction Stories (coll trans Gladys Evans from various sources 1973); it is sf. Their sf novel Vsadniki Niotkuda (1967 Smena nrs 7-13; 1968; trans George Yankovsky as Horsemen from Nowhere 1969 Moscow; vt Riders from Nowhere 1999) sees Earth visited by enigmatic Alien "clouds" which create Doppelganger-like "counterparts" of the human cast which turn out to be Communications devices constructed to facilitate meaningful First Contact between their makers and the human race. They can only be distinguished from the humans they have been modelled upon through their powers of memory, for (unlike humans) they remember everything. One of the Abramovs' short stories, "Gamma vremeni" (in Ten Imperatora, anth 1967), appears as "The Time Scale", trans D Matias, in Vortex: New Soviet Science Fiction (anth 1970) edited by C G Bearne.
