George Mallory
George Kenneth Mallory (1900-1986) was an American pathologist
GK Mallory was an American pathologist whose name endures through the Mallory-Weiss Syndrome/ lesion / tear. Born into a dynasty of distinguished pathologists, he followed in the footsteps of his father Frank Burr Mallory (1862-1921) for whom Mallory’s bodies are named; and older brother Tracy Burr Mallory (1896–1951) a distinguished pathologist who succeeded James Homer Wright as Chief of Pathology at Massachusetts General Hospital in Boston.
Beyond gastroenterology, Mallory made landmark contributions to cardiac pathology. In 1939, in collaboration with Paul Dudley White and Jorge Salcedo-Salgar, he co-authored a definitive study on the temporal histological changes of myocardial infarction based on 72 autopsy cases. This work was the first to systematically correlate infarct age with histological features, establishing diagnostic criteria that remain foundational in forensic and clinical cardiology. His methodological precision and integrative clinicopathological approach reflected a broader trend toward evidence-based pathology in mid-20th century medicine.
Mallory’s academic legacy extended through decades of teaching and departmental leadership. He served as Professor and Chair of Pathology at Boston University School of Medicine and Director of the Mallory Institute of Pathology from 1951 until his retirement in 1965. His publications include important contributions to renal and hepatic pathology, including a histochemical study of Mallory’s hyaline in liver disease. Though not as prolific as his father, George Kenneth Mallory’s scientific clarity and clinical relevance ensured his status as a foundational figure in American pathology.

Medical Eponyms
Mallory–Weiss Lesion (1929)
The characteristic of this lesion are longitudinal mucosal lacerations in the distal oesophagus and proximal stomach, which are usually associated with forceful or prolonged vomiting, retching or coughing. Originally identified in alcoholic patients presenting with severe upper gastrointestinal haemorrhage.
First described in 1929 by George Kenneth Mallory and Soma Weiss (1898–1942), who published 15 cases demonstrating that bleeding was due to mucosal fissures at the cardia, not varices or peptic ulcers.
In 1932, they published six further cases and explored the potential for acute tears to evolve into chronic ulcers. Their findings included cadaveric experiments simulating increased intragastric pressure to replicate the lesion. The syndrome is distinct from Boerhaave’s and Dieulafoy’s lesions based on histology and clinical presentation.
In their paper Mallory and Weiss identify – Johann Friedrich Hermann Albers (1833) as the first to document an ulcer in the lower oesophagus. Mallory and Weiss also comment on the work of Heinrich Irenaeus Quincke (1842–1922) and the less common oesophageal ‘peptic’ ulcer. Mallory and Weiss then separated their work from that reported by Georges Dieulafoy (1839-1911) based on histology.
Key Medical Contributions
Myocardial Infarction Pathology: Co-authored The speed of healing of myocardial infarction with Paul Dudley White and Jorge Salcedo-Salgar. This landmark study of 72 autopsies established the sequential histological changes following myocardial infarction, providing the first reliable histological criteria to date infarcts—a critical advance for both diagnosis and medicolegal pathology.
Renal Pathology: Published key experimental work on acute and chronic pyelonephritis, contributing to the understanding of renal inflammation and its progression.
Hepatic Pathology: Advanced the study of alcoholic liver disease through histochemical characterization of Mallory bodies (hyaline inclusions), continuing the work initiated by his father, Frank Burr Mallory.
