Peter Martin Duncan (1824–1891) was an English physician, geologist, and paleontologist known for his contributions to the study of fossil invertebrates, particularly corals and echinoderms. Born on February 7, 1824, in Norwich, England, he pursued a career in medicine but developed a strong interest in natural history, which led him to become a respected scientific figure in the 19th century.
Duncan was elected a Fellow of the Royal Society in 1863, reflecting the recognition of his scientific work. He authored numerous papers and monographs on paleozoic and mesozoic fossils and served as a professor of geology at King's College London and later as president of the Geological Society of London from 1874 to 1876. He also contributed to the "Paleontographical Society Monographs" and collaborated with other leading scientists of his time.
In addition to his geological work, Duncan held medical appointments and practiced as a surgeon. His interdisciplinary career exemplified the interconnectedness of medicine and natural sciences during the Victorian era.
Duncan died on January 1, 1891. His publications remain part of the historical record of 19th-century paleontology, particularly in the classification of fossil corals.
