Historical Timeline
200 B.C.E
4th Century B.C.E
Herophilus of Chalcedon
Herophilus of Chalcedon provided early anatomical descriptions of abdominal organs, including the pancreas, though without specific nomenclature.[3]
350 B.C.E
Aristotle
Aristotle referred to the ‘so-called pancreas” in Historia Annimalus while describing splanchnic vasculature.[3]
100 C.E.
Rufus of Ephesus
Rufus of Ephesus gave the first named description of the pancreas in On the Names of Various Parts of the Body.[3]
1500's
Jacobo Berengario da Carpi & David Edwardes
Anatomists such as Jacobo Berengario da Carpi (1522) and David Edwardes published increasingly detailed descriptions of the pancreas during the Renaissance.[3]
1642
Johann Georg Wirsung
Johann Georg Wirsung identified the pancreatic duct during autopsy, under the supervision of Thomas Bartholin and Moritz Hoffman.[3]
1668
Bernard Swalve
Bernard Swalve hypothesizes that the pancreas is involved with bile.[3]
1869
Paul Langerhans
Paul Langerhans described distinct clusters of pancreatic cells in his doctoral dissertation, Beitrage zur mikroskopischen Anatomie der Bauchspeicheldrüse, marking the first identification of pancreatic islets.[2]
1893
Gustave-Edouard Laguesse
Gustave-Edouard Laguesse named these clusters the islets of langerhans and proposed their endocrine function.[1]

Eponym:
The pancreatic islets are eponymously known as the islets of Langerhans, named after Paul Langerhans (1847-1888), a German physician and pathologist. Langerhans was born in Berlin and studied medicine at the Universities of Jena and Berlin, graduating in 1869 at the age of 22.[1] During his medical training, he worked under Emilie Du Bois-Reymond and developed a close academic association with Rudolf Vichrow, whose laboratory significantly influenced his scientific approach.[2,4]
Scientific Contributions:
Paul Langerhans made multiple contributions to the field of medical science. While completing his undergraduate degree, Langerhans used gold chloride techniques to describe dendritic, non-pigmentary cells located in the epidermis.[1] These cells later took on the eponym “Langerhans cells”.[1] Langerhans also worked in Virchow’s laboratory to study the macrophage system.[1]

In his 1869 dissertation, Beitrage zur mikroskopischen Anatomie der Bauchspeicheldruse, Langerhans distinguished exocrine acinar cells from clusters of morphologically distinct cells within the pancreas.[2] Although he did not assign a function to these clusters, they were later recognized as endocrine structures. In 1893, Gustave-Edouard Laguesse, proposed that these cell clusters had an exocrine role and formally named them the islets of Langerhans.[1,2] This discovery laid the foundation of understanding pancreatic endocrine physiology and the pathogenesis of diabetes mellitus.
