Who first described the pancreatic islets?

Paul Langerhans (1847–1888) was the first to provide a detailed description of microscopic pancreatic structures in the late 1860s. He noticed unique polygonal cells in the pancreas. It was not until 1893 that G.E. Laguesse discovered that the polygon-shaped cells were the endocrine cells of the pancreas that secreted insulin.
