Johan Coenraad van Hasselt

Johan Coenraad van Hasselt (born June 24, 1797 in Doesburg , † September 8, 1823 in Buitenzorg , today Bogor ) was a Dutch doctor and naturalist . Its official botanical author's abbreviation is " Hasselt ."

Live and act

Johan Coenraad van Hasselt was the son of the Mayor of Doesburg Barthold van Hasselt (1741–1819) and Bernardina Antonia nee. Rasch (1767-1849). Of his seven siblings, four sisters and two brothers, he was born the fifth. He was never married and had no children.

After attending the Latin school in his hometown, van Hasselt studied medicine at the University of Groningen from 1816 . In order to do justice to his great preference for natural history, he received lessons in natural history from the Groningen professor Theodorus van Swinderen (1784-1851) outside of his studies . Here he met the German zoologist Heinrich Kuhl , with whom he had a lifelong friendship. To improve their scientific knowledge, they traveled through Germany and France during their semester break . So van Hasselt met in Berlin with Martin Hinrich Lichtenstein together of him in his anatomical was a pillar studies. At the end of 1919 he stayed with Kuhl in Paris for several months , where they met Alexander von Humboldt and Georges Cuvier . In May of the following year, van Hasselt finished his studies with a doctorate in medicine.

On May 2, 1820, the Natuurkundige Commissie voor Nederlandsch-Indië was founded to research the Dutch colonies in the East Indian archipelago . As a doctor and naturalist, van Hasselt added to this four-person research team, which in addition to the delegating Kuhl also consisted of the taxidermist Gerrit van Raalten and the painter Gerrit Laurens Keultjes . In December 1820 they reached the island of Java after a six-month sea voyage with the ship Nordloh . Immediately after their arrival, they began their research, initially in the vicinity of Buitenzorg . Later they also carried out collecting activities on the slopes of the Salak and Pangrango volcanoes . In September 1821, Kuhl and Keultjes fell seriously ill and died shortly afterwards.

After mourning his deceased friend, van Hasselt continued the research work with van Raalten. At the beginning of 1822 they explored the coast of Batavia and from August the west coast of Java near Anjer . For the exploration of the until then still largely unknown province of Bantam , van Hasselt was supported in 1823 by the two draftsmen Jannes Theodorus Bik (1796–1875) and Antoine Maurevert due to van Raalten's illness. During this excursion, van Hasselt fell so seriously ill with dysentery that he could only be transported in a carrying chair. The expedition had to be broken off and Bik carried van Hasselt from Bantam back to Buitenzorg, where he died completely exhausted two days later on September 8th. He was buried next to his friend Heinrich Kuhl in the Botanical Garden , not far from the summer palace of the Governor General of Java.

Scientific importance

Genus of the fur snail Dermatobranchus ( van Hasselt , 1824)

The materials collected by van Hasselt and his companions in Java consisted of 200 skeletons and 200 skins from 65 species of mammals , 2000 bird hides , 1400 fish from 420 species, 300 amphibians and reptiles from 90 species. There are also many manuscripts that have already been started and a total of 1200 animal and plant drawings. The animals collected formed an important basis for the zoological collection of the Leiden Museum of Natural History ( Rijksmuseum van Natuurlijke Historie ), now Naturalis . Like Kuhl, van Hasselt was no longer able to process his collected material himself. The description of the vertebrates was carried out by Heinrich Boie , Georges Cuvier and Achille Valenciennes . Van Hasselt wanted to describe the orchids discovered in Java with the German botanist Carl Ludwig Blume , but that did not come about either.

The writing Contributions to Zoology and Comparative Anatomy , written with Kuhl in 1820, ensured scientific recognition. Some of his research reports from Java, written in letters, were published posthumously in the scientific journal Algemeene Konsten Letter-Bode ( Haarlem , 1788–1859). A number of the fish and mollusc species newly described there are still valid today.

Honors
