Carl Johan Josef Ernst Wiman (March 10, 1867 – June 15, 1944) was a Swedish palaeontologist, the first professor of palaeontology and historical geology at Uppsala University, and the father of Swedish vertebrate palaeontology. Wiman was instrumental in the construction of the Palaeontological Museum of Uppsala University (now part of the Museum of Evolution), which contains the largest collection of Chinese fossil vertebrate material outside China. He is responsible for naming the genera Helopus (renamed Euhelopus because Helopus was already in use) and Tanius, and the species Pentaceratops fenestratus and Parasaurolophus tubicen. He was also the first to suggest that the hollow cranial crests of lambeosaurine duckbill dinosaurs could be used as a horn-like noisemaker. Early life Family Wiman was born on 10 March 1867 in the recently inaugurated Märsta railway station, located on Husby-Odensala, Stockholm. Wiman's father was a Swedish army captain and Märsta's station-master between 1866 and 1879. Wiman's mother was from Aachen, the daughter of a wealthy Catholic pharmaceutical chemist. Wiman's childhood was spent accompanying his father on excursions in Uppsala, an amateur naturalist who was also considered to have been a keen hunter. Through these, he gained an interest in all aspects of nature, and performed extensive observations of plants and animals, such as collecting insects. His enjoyment for geology was most likely influenced by visits to his mother's home, where he came upon outcrops of cretaceous chalk that correspond to the Maastricht Formation. In 1885, aged 18, he was introduced to the study of palaeontology by a maternal uncle, a hotel proprietor in Valkenburg who was an amateur geologist and palaeontologist. Education In 1888 the 21-year-old Wiman began his studies at Uppsala University and in 1895 obtained his PhD degree with the thesis "Über die Graptoliten" (On Graptolites). Career Uppsala University He began his scientific career in 1891 under Arvid Högbom, centered around Jämtland and other Cambrian-Silurian underwater fossiliferous districts that were of interest but difficult to access. During this time Wiman also refined the method of freeing fossils by dissolving the matrix in hydrochloric or hydrofluoric acid, which helped advance the field of graptolite zoology. Around 1892 Wiman was made curator of the palaeontological collections present in the Geological Institute. In 1896 Wiman was made lecturer of palaeontology and pre-Quaternary historical geology by his PhD advisor, now professor, Arvid Högbom, who preferred to devote his time to other scientific endeavors. Nevertheless, Högbom constantly sought
