Ivan Antonovich (Antipovich) Yefremov, sometimes Efremov (Russian: Ива́н Анто́нович (Анти́пович) Ефре́мов; 23 April 1908 – 5 October 1972) was a Soviet paleontologist, science-fiction author and social thinker. He founded taphonomy, the study of fossilization patterns.

He was born in the village of Vyritsa in Saint Petersburg Governorate on 23 April 1908. His parents divorced during the Russian Revolution. His mother married a Red Army commander and left the children in Kherson to be cared for by an aunt who soon died of typhus. Yefremov survived on his own for some time, after which he joined a Red Army unit as a "son of the regiment" and went to Perekop with it. In 1921, he was discharged and went to Petrograd (now Saint Petersburg) to study. He completed his education there while combining his studies with a variety of odd jobs. He later commented that "the Revolution was also my own liberation from philistinism" (Russian: "Революция была также и моим освобождением от мещанства").

In 1956, due to the influence of academician Petr Sushkin, he became interested in paleontology. Yefremov entered the Leningrad State University but dropped out later. As early as 19, he made several discoveries ^[which?] and published a monograph co-authored with Alexey Bystrow, which was later awarded by the Linnean Society of London.

In the mid-1930s, he took part in several palaeontological expeditions to the Volga region, the Urals, and Central Asia. He headed a research laboratory at the Institute of Paleontology. In 1935, he took exit examinations and graduated from the Leningrad Mining Institute. The same year he got his Candidate of Science degree in biological sciences. In 1941, he got his doctorate in biological sciences. In 1943 he received the title of Professor.

In the 1940s, Yefremov developed a new scientific field called taphonomy, for which he was awarded the Stalin Prize in 1952. His book, Taphonomy, was published in 1950. He applied many taphonomic principles in his fieldwork during a palaeontological expedition to the Gobi Desert in Mongolia. During these years, he was recognized as a successful scientist and won a state science award. Many American researchers ^[who?] called Yefremov the father of modern paleontology,^{[citation needed]} who merged geological and palaeontological data into a single science.

Yefremov wrote his first work of fiction, a short story, in 1944. His first novel The Land of Foam (Great Arc, 1946) was published in 1946. The Road of Winds novel was written on a basis of scientific expeditions in Mongolia (1946–1949). His most widely recognized science fiction novel Andromeda Nebula came out in 1957. This book is a panegyric to utopian "communist" future of mankind. The society developed such that there is no material inequality between individuals, and each person is able to pursue their self-development unrestricted. The intergalactic communication system binds mankind into the commonwealth of sentient civilizations of the Universe - the Great Ring of Civilizations. The book became a moral guideline for many people in the Soviet Union. Besides the heavy didactic aspect, the book also contained an interesting space travel adventure subplot, so a lot of people appreciated it for its educational and entertainment value. Algis Budrys compared Yefremov's fiction style to that of Hugo Gernsback.^[1]

With the time the socio-political circumstances in the world changed to more and more worrying, that changes were reflected in The Bull's Hour novel. Yefremov tried to give a warning about forthcoming catastrophes in environment, ethics and social sphere. Many considered the novel as a disguised criticism of the USSR, though the later researchers proved it wrong. The novel mostly showed the dead-end perspectives of Maoism and gangster capitalism. The government accused the novel of Anti-Sovietism and banned it from publishing up to the end of the 1980s.

Yefremov's last novel was Thais of Athens, published in 1972. The narration was placed in the times of Alexander the Great. Its multiple topics included little-known female cults, questions of women inner worlds, their roles in global history; he raised questions of religion, cultural genesis, search for beauty and truth.

Yefremov was married three times. His first marriage in the early 1930s, to Ksenia Svitalskaya, was short-lived and ended in divorce. In 1936, he married paleontologist Elena Dometevna Konzhukova, with whom they had a son, Allan Ivanovich Yefremov. After his wife died on 1 August 1961, he married Taisiya Iosifovna Yukhnevskaya in 1962. His last novel Thais of Athens, which was posthumously published in 1973, is dedicated to her.
