Thorild Wulff (born April 1, 1877 in Gothenburg, died late August or early September 1917 in Northwest Greenland) was a Swedish botanist and polar explorer.
Gothenburg is the second-largest city in Sweden, fifth-largest in the Nordic countries, and capital of the Västra Götaland County. It is situated by Kattegat, on the west coast of Sweden, and has a population of approximately 570,000 in the city center and about 1 million inhabitants in the metropolitan area.
Greenland is an autonomous constituent country of the Kingdom of Denmark between the Arctic and Atlantic oceans, east of the Canadian Arctic Archipelago. Though physiographically a part of the continent of North America, Greenland has been politically and culturally associated with Europe for more than a millennium. The majority of its residents are Inuit, whose ancestors began migrating from the Canadian mainland in the 13th century, gradually settling across the island.
Botany, also called plant science(s), plant biology or phytology, is the science of plant life and a branch of biology. A botanist, plant scientist or phytologist is a scientist who specialises in this field. The term "botany" comes from the Ancient Greek word βοτάνη (botanē) meaning "pasture", "grass", or "fodder"; βοτάνη is in turn derived from βόσκειν (boskein), "to feed" or "to graze". Traditionally, botany has also included the study of fungi and algae by mycologists and phycologists respectively, with the study of these three groups of organisms remaining within the sphere of interest of the International Botanical Congress. Nowadays, botanists study approximately 410,000 species of land plants of which some 391,000 species are vascular plants, and approximately 20,000 are bryophytes.
He obtained his doctorate degree from Lund University in 1902 based on observation he had made during a Swedish-Russian geodesy expedition to Svalbard.
Lund University is a public university, often ranking among the world's top 100 universities. The university, located in the city of Lund in the province of Scania, Sweden, arguably traces its roots back to 1425, when a Franciscan studium generale was founded in Lund next to the Lund Cathedral. After Sweden won Scania from Denmark in the 1658 Treaty of Roskilde, the university was founded in 1666 on the location of the old studium generale next to Lund Cathedral.
Sweden, officially the Kingdom of Sweden, is a Scandinavian Nordic country in Northern Europe. It borders Norway to the west and north and Finland to the east, and is connected to Denmark in the southwest by a bridge-tunnel across the Öresund, a strait at the Swedish-Danish border. At 450,295 square kilometres (173,860 sq mi), Sweden is the largest country in Northern Europe, the third-largest country in the European Union and the fifth largest country in Europe by area. Sweden has a total population of 10.2 million of which 2.4 million has a foreign background. It has a low population density of 22 inhabitants per square kilometre (57/sq mi). The highest concentration is in the southern half of the country.
Russia, officially the Russian Federation, is a transcontinental country in Eastern Europe and North Asia. At 17,125,200 square kilometres (6,612,100 sq mi), Russia is the largest country in the world by area, covering more than one-eighth of the Earth's inhabited land area, and the ninth most populous, with about 146.77 million people as of 2019, excluding Crimea. About 77% of the population live in the western, European part of the country. Russia's capital, Moscow, is the largest metropolitan area in Europe proper and one of the largest cities in the world; other major cities include Saint Petersburg, Novosibirsk, Yekaterinburg and Nizhny Novgorod. Extending across the entirety of Northern Asia and much of Eastern Europe, Russia spans eleven time zones and incorporates a wide range of environments and landforms. From northwest to southeast, Russia shares land borders with Norway, Finland, Estonia, Latvia, Lithuania and Poland, Belarus, Ukraine, Georgia, Azerbaijan, Kazakhstan, China, Mongolia and North Korea. It shares maritime borders with Japan by the Sea of Okhotsk and the U.S. state of Alaska across the Bering Strait. However, Russia recognises two more countries that border it, Abkhazia and South Ossetia, both of which are internationally recognized as parts of Georgia.
Wulff was research assistant in horticulture ("Centralanstalten för försöksväsendet på jordbruksområdet") 1905–09, docent of botany at Stockholm University College 1909–13. In 1911 he travelled to Iceland with his friend the author Albert Engström who gave an account of the journey ("Åt Häcklefjäll" 1913).
Iceland is a Nordic island country in the North Atlantic, with a population of 348,580 and an area of 103,000 km2 (40,000 sq mi), making it the most sparsely populated country in Europe. The capital and largest city is Reykjavík, with Reykjavík and the surrounding areas in the southwest of the country being home to over two-thirds of the population. Iceland is volcanically and geologically active. The interior consists of a plateau characterised by sand and lava fields, mountains, and glaciers, and many glacial rivers flow to the sea through the lowlands. Iceland is warmed by the Gulf Stream and has a temperate climate, despite a high latitude just outside the Arctic Circle. Its high latitude and marine influence keep summers chilly, with most of the archipelago having a tundra climate.
Albert Engström was a Swedish artist, author and member of the Swedish Academy from 1922.
He participated in the Second Thule Expedition led by Knud Rasmussen from Thule to Cape Bridgman in the northeastern corner of Peary Land. On the return trip, the expedition suffered from bad weather and insufficient supplies, resulting in casualties, one of them being Wulff. He died from fatigue near Cape Agassiz off the Humboldt Glacier.
Knud Johan Victor Rasmussen was a Greenlandic–Danish polar explorer and anthropologist. He has been called the "father of Eskimology" and was the first European to cross the Northwest Passage via dog sled. He remains well known in Greenland, Denmark and among Canadian Inuit.
Pituffik is a former settlement in northern Greenland, located at the eastern end of Bylot Sound by a tombolo known as Uummannaq, near the current site of the American Thule Air Base. The former inhabitants were relocated to the present-day town of Qaanaaq. The relocation and the fallout from the 1968 Thule Air Base B-52 crash in the vicinity are a contentious issue in Greenland's relations with Denmark and the United States.
Cape Bridgman is a headland in the Wandel Sea, Arctic Ocean, northeast Greenland.
The Greenlandic plant species Braya thorild-wulffii (Brassicaceae) was named after him in 1923. The Wulff Land peninsula in Northern Greenland is similarly named for him.
Braya is a genus in the Brassicaceae family.
Brassicaceae or Cruciferae is a medium-sized and economically important family of flowering plants commonly known as the mustards, the crucifers, or the cabbage family. Most are herbaceous plants, some shrubs, with simple, although sometimes deeply incised, alternatingly set leaves without stipules or in leaf rosettes, with terminal inflorescences without bracts, containing flowers with four free sepals, four free alternating petals, two short and four longer free stamens, and a fruit with seeds in rows, divided by a thin wall.
Wulff Land is a peninsula in far northwestern Greenland. It is a part of the Northeast Greenland National Park.

He took his licentiate exam 1931 at Stockholm University and obtained his doctorate degree in botany at Lund University in 1937. In his thesis, he coined the term Beringia for the ice-age land bridge between Eurasia and North America. From 1945 to 1961, he was a professor and head of the Botany Section at the Swedish Museum of Natural History. In 1953, he was elected to the Royal Swedish Academy of Sciences as member number 977.
Jens Wilhelm August Lind was a Danish apothecary, botanist and mycologist. He was a pupil of Emil Rostrup and published a full account of all fungi collected in Denmark by Rostrup. These were mainly microfungi, such as plant pathogens. He also wrote accounts on microfungi from Greenland and elsewhere, mainly based on collections made by other persons on expeditions, e.g. Gjøa expedition and the Second Thule Expedition. Combining his pharmaceutical and mycological knowledge, he was early in experimenting on chemical control of plant pathogens and recommending it to practitioners. He also - together with Knud Jessen - wrote an account on the immigration history of weeds to Denmark.
