Blaise Cronin (born 1949) is an Irish-American information scientist and bibliometrician. He is the Rudy Professor Emeritus of Information Science at Indiana University,^[1] Bloomington, where he was Dean of the School of Library and Information Science for seventeen years. From 1985 to 1991 he held the Chair of Information Science and was Head of the Department of Information Science at the University of Strathclyde in Glasgow, U.K.

Cronin was born in Newry in Northern Ireland in 1949.^[2] He was delivered by his grandfather, Dr. Thomas Cronin who was a surgeon. Cronin's father Gerald was the Town Clerk and his mother, Sheila Devenish-Meares, was a music teacher and the leader of the Newry Symphony Orchestra. Cronin wrote about his hometown of Newry in his book titled "Your Newry Bucket List: 70 Things to do in Newry Before You Die."^[2]

Cronin began his education at the Abbey Christian Brothers' Grammar School where he played football. He went on to attend Trinity College Dublin where he earned a master's degree and then Queen's University Belfast where he earned a PhD and a DSSc.^[2] Cronin went on to become Head of Department and Professor of Information Science at the University of Strathclyde in Glasgow around 1985.^[3] Circa 1990, he became a Rudy Professor Emeritus of Information Science at Indiana University in Bloomington, Indiana.^[4] Circa 2009, Cronin became editor-in-chief of the Journal of the Association for Information Science and Technology until 2015.^[5]

Cronin is well known for his work in bibliometrics and scientometrics. In over two decades, Cronin has written and edited over 300 research articles, monographs, technical reports, conference papers, and more.^[3] He is known for his research "focused on collaboration in science, scholarly communication, citation analysis, the academic reward system and cybermetrics - the intersection of information science and social studies of science."^[3] His research focused heavily on not only Information Science but in understanding the importance of acknowledgements in scholarly papers. Through his writing, Cronin argues for consistency and conformity in citation in order to build a more complete picture of how knowledge is shared and disseminated within the scientific community.^[6][7] Cronin's work also includes consulting both in the United Kingdom and abroad in over 30 countries.^[3][4] Additionally, he has been a keynote speaker at various conferences in several different countries.^[3] Around the late 1980s and early 1990s, Cronin became a founding co-director for the electronic publishing start-up Crossaig, which was later acquired by ISI.^[8]
