Júlio César de Mello e Souza (Rio de Janeiro, May 6, 1895 – Recife, June 18, 1974), was a Brazilian writer and mathematics teacher. He was well known in Brazil and abroad by his books on recreational mathematics, most of them published under the pen names of Malba Tahan and Breno de Alencar Bianco. He wrote 69 novels and 51 books of mathematics and other subjects, with over than two million books sold by 1995. His most famous work, The Man Who Counted, saw its 54th printing in 2001. Júlio César's most popular books, including The Man Who Counted, are collections of mathematical problems, puzzles, curiosities, and embedded in tales inspired by the Arabian Nights. He thoroughly researched his subject matters — not only the mathematics, but also the history, geography, and culture of the Islamic Empire which was the backdrop and connecting thread of his books. Yet Júlio César's travels outside Brazil were limited to short visits to Buenos Aires, Montevideo, and Lisbon: he never set foot in the deserts and cities which he so vividly described in his books.
