Soon after he joined Rutgers, Arthur became department chair. With a long reign as chair followed by other essential roles, he was instrumental in building up Statistics into the leading department it is today, although he once claimed that one thing he loved about Rutgers was that he could pretend the administration didn't exist and the administration thought he didn't exist. Arthur was known to be an inspiring and caring teacher. He supervised several students, who themselves are now leaders on their own. In addition to his service at Rutgers, Arthur had also provided outstanding service to the statistics profession, including serving as Editor of the Annals of Statistics, Co-Editor of the Journal of Multivariate Analysis, and Associate Editor of several other journals.
Arthur developed wide ranging and fundamental results in decision theory, admissibility, Bayes procedures, sequential tests, order restricted inference, and multiple testing. One of his long-time collaborators Harold Sackrowitz said "His research was always guided by relevance to the area. He preceded Google as a search engine for his breadth of knowledge of people and work across Statistics." Among other distinctions, Arthur was honored as a Fellow of the Institute of Mathematical Statistics, the American Statistical Association, and the International Statistical Institute.
Arthur will be greatly missed for his enormous intellect, kindness, and optimism. He leaves behind his loving wife of sixty-four years, Anita, his devoted son Richmond and daughter Elizabeth, and his cherished grandchildren Genevieve and Troy Arthur.
The Department of Statistics at Rutgers University will establish an Arthur Cohen Lecture as one of the major annual events of the department. The Rutgers flag will fly at half-mast on November 5, 2021, in his memory. A virtual memorial gathering will be held on September 17, 2021, and a celebratory research conference with colleagues, students and family members will be held in Arthur's honor at Rutgers University of January 14, 2022.
Written respectfully by the colleagues of Arthur's at the Rutgers Statistics Department.
For more detailed information for attending the memorial gathering on 9/17/2021 and the research conference on 1/14/2022, please contact the Department of Statistics at Rutgers at
