With Gustave Bertrand's 1973 publication of his "Enigma", substantial information about the origins of Ultra began to seep out; and with F. W. Winterbotham's 1974 best-seller, "The Ultra Secret", the dam began to burst. Still, many aspiring authors were not averse to filling gaps in their information with whole-cloth fabrications. Rejewski fought a gallant (if, into the 21st century, not entirely successful) fight to get the truth before the public. He published a number of papers on his cryptologic work and contributed generously to articles, books, and television programs. He was interviewed by scholars, journalists, and television crews from Poland, East Germany, the United States, Britain, Sweden, Belgium, the Soviet Union, Yugoslavia, and Brazil.
