Anders Planman also calculated the correct longitude for six locations on the way, among them Kajaani, Mikkeli and Hämeenlinna. He could do this partly because he used surveying tools for his astronomical observations; these were some of the most exact contemporary measuring tools. The minor planet 2639 Planman is named after Anders Planman. Anders Planman Anders Planman (1724 – 25 April 1803) was a Finnish astronomer, professor of physics and mathematician. He was one of the first people to make systematical astronomical observations in Finland. Planman came from a Swedish-speaking Finnish family and his father was a lieutenant. He studied at the
Uppsala University the previous century, but eventually a larger emphasis on sciences and practically useful knowledge developed. The innovative mathematician and physicist Samuel Klingenstierna (1698–1765) was made a professor in 1728, the physicist and astronomer Anders Celsius in 1729, and Carl Linnaeus was made professor of Medicine with Botany in 1741. The university was not immune to the parliamentary struggle between the parties known as the "Hats" and the "Caps", with the former having a preference for hard sciences and practical knowledge. The Hat government then in power established a chair in economics ("Œconomia publica") in 1741 and called Anders Berch as
