Short answers, pulled from the story.
Ole Worm (1588-1654) was a Danish physician, natural historian, and antiquary who taught at the University of Copenhagen. He is known for debunking the existence of the unicorn, cataloging runic inscriptions, assembling the famous Museum Wormianum collection, and lending his name to the Wormian bones of the skull.
Wormian bones are small bones that fill the gaps between the plates of the skull, known as cranial sutures. They are named after Ole Worm in recognition of his contributions to embryology, which were his chief contribution to medicine.
In 1638, Worm determined through empirical investigation that the unicorn did not exist and that the horns sold as unicorn horn were actually the tusks of narwhals. He then conducted experiments to test whether narwhal horn retained the anti-poison properties attributed to unicorn horn.
Museum Wormianum was Ole Worm's catalog of his cabinet of curiosities, covering minerals, plants, animals, and archaeological and ethnographic objects. It was published after his death in 1654 and is divided into four books.
An illustration of Worm's pet great auk is the only known depiction of a living member of that species. Because the great auk is now extinct, Worm's drawing serves as the only portrait of a living bird.
Worm published Fasti Danici in 1626, followed by Runir seu Danica literatura antiquissima in 1636, a compilation of transcribed runic texts. His 1643 work Danicorum Monumentorum was the first written study of runestones and remains one of the only surviving sources for several Danish runestones and inscriptions that are now lost.
