History – Named after John Dalrymple (1803-1852), an English ophthalmologist who received his medical doctorate from the University of Edinburgh in 1827. He would spend his entire, albeit short due to ill health, career as an eye surgeon at the Royal Ophthalmic Hospital in London. He was also a skilled histologist and microscopist and was the first to publish on the findings of the Bence Jones protein of multiple myeloma. His eponymonic examination finding was published, shortly before his untimely death at 47, in his magnum opus “Pathology of the Human Eye” in 1852.
