During the years 1921 and 1922 together with Hašek he was a publisher of the first paperback of The Good Soldier Švejk. Sauer raised enough funds to publish the first edition and after obtaining funds from the sales, he persuaded Hašek to write the sequel. At the end of the World War II he was arrested for distributing publications by T. G. Masaryk. He was relocated to Terezín and released in 1945 because he suffered from tuberculosis and later died from it in 1947. Before his death he made general confession in the Franciscan monastery. After being given the last rites, he died in the Pod Petřínem hospital. Before his death he apparently regretted about the demolition of Marian Column and he begged forgiveness to the priest. His spiritual evolution is mentioned in the poem Pražská legenda by Václav Renč. In the Prague district Žižkov there is a street named after him. František Sauer published under the pseudonym Fr. Habán, Franta Habán from the Žižkov or Franta Kysela as well. In 1911–1935 he was publishing to a few journals such as České slovo, Právo lidu, Rudé právo or Trn. • Naše luza jesuité a diplomaté   • In memoriam Jaroslava Haška   • Pašeráci   • Emil Artur Longen a Xena  • Pašeráci  • Haškův poslední podnik  • Franta Habán ze Žižkova  • Franta Habán ze Žižkova (1933)  • Haškův poslední podnik (1946)  • 1947 Čapkovy povídky  • 1931 Miláček pluku  • 1931 Poslední bohém  • 1931 Skalní ševci  • 1931 Ze soboty na neděli  • František Sauer is a character in a novel "Anna proletářka" by Ivan Olbracht  • Antonín Zápotocký written about him as "Franta Habán" in a novel Bouřlivý rok
