Ludwik Fleck (1896-1961) is considered a pioneer of modern research into science. He is the originator of such concepts as Denkstil [= “thought style”] and Denkkollektiv [= “thought collective”], terms currently in use. Nevertheless, the monograph he published in 1935 with Schwabe Verlag in Basel, Entstehung und Entwicklung einer wissenschaftlichen Tatsache [Genesis and Development of a Scientific Fact, Chicago 1979], went unnoticed for decades, as did his shorter epistemological works and writings on the sociology of knowledge. It was not until Thomas S. Kuhn published a brief tribute to Fleck in the preface to The Structure of Scientific Revolutions (Chicago 1962), his bestselling work on the history of science, that a belated reception of Fleck’s work began. From the late 1980s on recognition of his significance grew steadily and ultimately earned Fleck’s work its current status as a classic. Despite his posthumous renown as a historian of science, however, during his lifetime Fleck was a practicing physician and natural scientist. As a researcher and head of a laboratory he participated successfully in work in the field of bacteriology and serology, and the number of his publications in medicine and the natural sciences, published in respected medical journals, far outweighs those in the field of reflection on knowledge.
Ludwik Fleck's life as a Jewish scientist in the 20th century took him through the university as well as the ghetto and the concentration camp, through the Europe of world wars and totalitarian systems, and ultimately to Israel.
Fleck’s main writings on the theory of science are available in English as:
