Cornelius Knudsen was a manufacturer of scientific instruments based in Copenhagen, Denmark.
The company gained an international reputation and its instruments were used on a number of polar expeditions.
Knudsen's son Theodor Valdemar Cornelius Knudsen (1844-) served as a cadet on the corvetette Heimdal in 1860.
He formed a friendship with Prince Wilhelm, the later George I of Greece, who also served as a cadet on the ship. Back on land,
he initially worked in his father's workshop and then attended classes at the College of Advanced Technology.
He headed the family firm from 1870 and continued it alone after his father's death. On 27 May 1884, he changed his last name to Cornelius-Knudsen.
Cornelius-Knudsen's sons Aage Cornelius Knudsen (1879-) and Jens Cornelius Knudsen (1885-) were assistant directors from 1905 and 1908.
The company was in 1950 owned by Anna Cornelius-Knudsen (1909-).

Пурка для кукурузы.
PORTABLE DUTCH CORN SCALE OUTFIT, c. early 19th century. This "Amsterdam corn scale" outfit, when assembled, forms a brass cylinder 3-3/8" in diameter and 7" tall (8.5 x 18 cm). The two halves form the weighing vessels, one for corn and one for weights. The 5-1/2" long cut steel balance beam, with its brass hangers, would be connected to the vessels by chain or cord running through the guides along the sides. The original turned brass weights, of traditional mushroom form, are also present, marked 5, 10, 20, 40, and 60. Condition is fine through-out noting cleaning residue in the crevices. The "Amsterdamse korenschaal" was used to determine the specific gravity of a grain sample, as a measure of its quality. The form was apparently used only in Holland. Examples are uncommon; we find one illustrated in Kisch (Fig. 21). (7414) $950.
