He was born in 1894 in Poznań as a son of a printer and publisher, Antoni Fiedler, from whom he learned his love for nature. Fiedler later said about his father that “he taught me to love things that other people would overlook.” He graduated from high school in Poznań, and then studied philosophy and natural sciences at the Jagiellonian University and the University of Poznań. His education was interrupted by the outbreak of World War I. In the years 1918-1919, he took part in the Wielkopolska Uprising.
He made his debut in 1917 with the series of poems “Red light of a fire” published in the Poznań biweekly “Zdrój”. In the years 1922-1923, he began his studies at the Academy of Graphic Arts in Leipzig, obtaining the title of master of chemigraphy. In 1926, he published the first report from his expedition, “Przez wiry i porohy Dniestru”. In 1928, he made his first major trip to southern Brazil. Five years later, he fulfilled his greatest dream by embarking on a journey to the Amazon. The expedition resulted in the book “The River of the Singing Fish”, which was highly appreciated by readers. His next bestseller, “Resin-Scented Canada”, was published in 1936. A year later he was already in Madagascar.
“My father taught me to love things that other people would overlook.”
World War II found Fiedler in Tahiti. He took the military service again. In February 1940, he reached Great Britain through France, where he met Polish airmen participating in the Battle of Britain, about whom he wrote the book ” Squadron 303 “. In the years 1942-1943, he was on Polish merchant ships. In 1946, he returned to Poland with his wife, Maria Maccariello, and settled in Puszczykowo near Poznań. It is there where novels for young people were written: “Little Bison”, “Robinson’s Island”, “Orinoco”. From 1956 he returned to his travels: he visited Indochina, Brazil, Guyana, Madagascar, Canada, and West Africa several times. He also wrote two autobiographical books: “My Father and Oaks” and “Male Age – Victorious”.
In his life he made 30 trips and journeys. He wrote 32 books that were published in 23 languages with a circulation of over 10 million. In his books, Fiedler teaches respect for other cultures and customs, at the same time vividly describing nature. From his travels, he brought back rich zoological and botanical collections, which he donated to scientific institutions in Poznań.
