Ludvík Souček was probably the best-known author of science fiction in Czechoslovakia. He graduated at Medical faculty of Charles University in Prague as a dentist in 1951 and started his professional life at the dental clinic as an assistant. Later, he joined the military and became an officer. He spent two years in Korea as a member of Czechoslovak peace mission after Korean War. Next, he was employed as a dentist in the Central Military Hospital in Prague, then served at Czechoslovak Ministry of National Defence. He shortly worked at the Central Committee KSČ . The same year he was employed in the military redaction of the Czechoslovak Television as an editor and later in the Albatros publishing house. Because of serious disease, he went into disability pension in 1976. He was a member of KSČ all his life, and the ideology definitely profoundly influenced his literary work. In spite of his deep communist persuasion, Souček arguably remains the most popular and most widely known author of Czech Science fiction. Non-fiction is one of the most important elements in Souček's writings. Souček is actually best known as the Czech Däniken. His books of "Portents" are collections of Däniken-styled non-fiction essays on striking, surprising, obscured, or otherwise "not-yet" explained facts from the history of mankind, which are indeed hard to impossible to explain either given the present dayscientific knowledge or our assumptions on the scientific knowledge or technology level of ancient civilizations. Similarly to his forerunner Däniken, Souček hinted that cultural and architecture phenomena some natural catastrophes, mythologies and biblical histories can be best explained through an alien, extraterrestrial intervention. Unlike his predecessor, Souček does not push the idea of an alien intervention too hard, he gives ample space to alternative explanations and never actually states that it must have been "them". Souček's essays also have rather high scientific standard and contain good discussion of relevant published sources. Science fiction trilogy of "Blind Birds" contains a very strong non-fiction element and it should be seen as continuation of the best Czech Science fiction tradition. Souček's "Blind Birds" actually mimic the method and composition of "War with the Newts, 1937" by Karel Čapek. Both Čapek and Souček initiate their plot deeply rooted in the present day setting and both of them keenly criticize the present day social and political reality. Souček builds a virtuous mixture of scientific fact and made up archeological discoveries in France, Iceland, Brazil, and Mars. Both Čapek and Souček develop the fantastic element only very slowly, starting with the very sober 1st book, accelerating in the 2nd, and culminating in the 3rd book as hard SF par excellence: The victory of Newts and near extinction of human race, Čapek; International discovery and rescue mission to Mars, Souček.
