Became instructor at the pilot school of Karlskrona in 1745. In an official communication pointing out the inadequacy of Swedish sea charts, Wallman called for more astronomical observations and more careful measurements. Appointed commander and director of pilots in 1755, he was handed the opportunity of personally directing marine measurements, principally on the southern coastline. A successor summed up Wallman's career: 'Nobody before or after has made such great personal contribution to the sounding of our coasts'

Ca. 1597-1644.
Holländsk kartograf, son till Jodocus Hondius. Från 1643 övertog han utgivningen av Mercator-Hondius-atlasen. Förutom talrika utgåvor av denna, som han efter hand reviderade ganska grundligt, gav han 1627 ut en kopia av sin fars världskarta, och 1629 en karta över Brabant. 1636 kom hans svåger Joannes Janssonius (se denne) med i kartarbetet.

Frisius, Gemma. [Reinerszoon, Jemme.]
Biografiska uppgifter:9 december 1508 - 25 maj 1555.
Gemma Frisius was a physician, mathematician, cartographer, philosopher, and instrument maker. He created important globes, improved the mathematical instruments of his day and applied mathematics in new ways to surveying and navigation.
Frisius was born in Dokkum, Friesland (present-day Netherlands) of poor parents, who died when he was young. He moved to Groningen and studied at the University in Leuven beginning in 1525. He received the degree of MD in 1536 and remained on the faculty of medicine in Leuven for the rest of his life. His oldest son, Cornelius Gemma, edited a posthumous volume of his work and continued to work with Ptolemaic astrological models.
While still a student, Frisius set up a workshop to produce globes and mathematical instruments. He became noted for the quality and accuracy of his instruments, which were praised by Tycho Brahe, among others. In 1533, he described for the first time the method of triangulation still used today in surveying. Twenty years later, he was the first to describe how an accurate clock could be used to determine longitude. Jean-Baptiste Morin (1583–1656) did not believe that Frisius' method for calculating longitude would work, remarking, 'I do not know if the Devil will succeed in making a longitude timekeeper but it is folly for man to try.'
Frisius created or improved many instruments, including the cross-staff, the astrolabe and the astronomical rings. His students included Gerardus Mercator (who became his collaborator), Johannes Stadius, John Dee, Andreas Vesalius and Rembert Dodoens.
A lunar crater has been named after him.
