Alex Csiszar

Alex Csiszar is a professor of the history of science at Harvard University. His research focuses on the history of science in modern Europe specifically. Csiszar publishes primarily on the history of communications media and information technology in the sciences. His investigates how formats and genres, newspapers, journals, books, and databases, have evolved in conjunction with changes in how groups learned about the natural world, and the criteria they use to trust the claims of others.

His first book, The Scientific Journal: Authorship and the Politicsl of Knowledge in the Nineteenth Century (University of Chicago Press, 2018) follows the rise of the modern scientific journal in Western Europe, focusing on the changing relationship between authorship and scientific identity, transformations in systems of judgement, and developing notions of trust and public accountability. It is the first book to attempt to explain how being an investigator of the natural world came, by the early twentieth century, to be identified closely with being a very particular kind of author. He is currently writing a book titled Rank and File: From the Literature Seach to Algorithmic Judgment.
