Our Division of the International Academy of Pathology (IAP) is deeply saddened to announce the passing of our esteemed pathology colleagues, Nobel Laureate Emeritus Professor Robin Warren AC and Professor Christopher Fletcher. 

Professor John Robin Warren AC (11 June 1937 – 23 July 2024)

Professor Robin Warren made significant strides in anatomical pathology at Royal Perth Hospital throughout the 1970s. On his birthday in 1979, he made the pivotal discovery of Helicobacter pylori bacteria associated with chronic gastritis, laying the foundation for his groundbreaking collaboration with Professor Barry Marshall. Their research earned them the prestigious Nobel Prize in Medicine in 2005 and solidified their place in medical history.

Professor Christopher Fletcher (13 March 1958 – 28 July 2024)

Professor Christopher Fletcher graduated from St. Thomas’s Hospital Medical School in London. He was a Professor of Pathology at Harvard Medical School, Director of Surgical Pathology at Brigham and Women’s Hospital in Boston, Massachusetts, and Chief of Onco-Pathology at the Dana-Farber Cancer Institute in Boston. Professor Fletcher worked extensively on cytogenetic/morphologic correlations in soft tissue tumors and served as Chairman of the WHO Working Group on the classification of soft tissue tumours. Beyond all he was an excellent teacher and mentor to many. 

Both have left an indelible mark on the international and Australasian pathology communities. Their legacies will continue to inspire future generations in the field of pathology and beyond. Please join us in extending our deepest condolences to their families and loved ones during this difficult time.
