[Translating Fleck: an interview with Georg Otte and Mariana Camilo de Oliveira].

Recent research in the history of science and the sociology of knowledge, where science is understood as knowledge in circulation, has called attention to the importance of studying the translation of scientific works, which involves not only the social circumstances of their production but also how these works are received. The testimony presented here was given by the translators of the Portuguese version of Ludwik Fleck's Entstehung und Entwicklung einer wissenschaftlichen Tatsache (Genesis and development of a scientific fact), a work that probably influenced Thomas Kuhn's now classic The structure of scientific revolutions. Our goal is to offer resources for understanding Fleck's importance in Brazilian studies on the circulation of scientific knowledge.
