Allan. Thus the value of the collection was ultimately recognized prior to Giesecke's return to Europe. Researches in Greenland other than in mineralogy Giesecke's travels up and down the coast of Greenland proved important from the perspective of geography. On his return he was consulted by mariners such as John Franklin and William Scoresby, who played a role in the eventual discovery of the Northwest Passage, the famously elusive sea route around the northern edge of North America. He also collected botanical specimens. These included some bryophyte species growing on rocks. Giesecke collected specimens of the Greenlandic bellflower, which he found deviated much from the European forms, and sent them to the botanist Lorenz Chrysanth von Vest. The latter established a new species and named it Campanula gieseckiana to the honour of Giesecke. The new species was formally published by Roemer and Schultes in the 16th edition of Linnaeus' Systema Vegetabilium. Lastly, Giesecke contributed to the ethnography and human history of Greenland through his observations of the Eskimos and of the extinct Viking settlements there. A number of places in Greenland are named for him, e.g. Giesecke Dal on Disko Island, Giesecke Isfjord near Upernavik and lake Gieseckes Sø close to Kangerlussuaq. Professor in Dublin On his return from Greenland Giesecke was lacking not only European clothing but also money and a source of income. But his scientific accomplishments were to produce a major shift in his fortunes. Thomas Allan had already recognized the importance of Giesecke's collections, and he invited Giesecke to stay with him in his home in a fashionable district of Edinburgh. It was at this time that Giesecke's portrait (shown above) was painted by the famous portraitist Henry Raeburn. After a few weeks, Allan encouraged Giesecke to apply for a new Professorship of Mineralogy in the Royal Dublin Society. Despite serious competition, Giesecke won the appointment and took up the position in 1813. At the outset of his appointment he knew no English, but his gift for languages enabled him to make up for this lack through quick study; he eventually published extensively in English. Giesecke continued reporting his earlier investigations and other writings. In the same year 1814 he was admitted to the Order of the Dannebrog by King Frederick VI of Denmark; henceforth in Ireland he styled himself "Sir Charles Lewis Giesecke," so indicating the Danish honour, and using the English versions of German
