Enrico Fermi was one of the greater physicists of the XX century. In 1934, he
gave several lectures in Brazil. Invited by Theodoro Ramos to work in S\~ao
Paulo, he preferred to stay in Rome and went to the USA in 1938. However, Fermi
recommended Gleb Wataghin to come in his place. Wataghin made history in
Brazil, becoming one of the first Professors of the future S\~ao Paulo
University. Besides his relevance to the History of Science, Fermi eventually
leaved an indelible mark on the creation and institutionalization of national
scientific research due to the indication of Wataghin. Despite this fact, very
little is known about Fermi's trip to Brazil. This work tries to reconstruct
the fullest possible steps of the famous Italian physicist in our lands.Comment: 13 p, in Portuguese. Accepted for publication in Estudos
