His priority in this discovery, however, went unrecognized for many years. Thus what should really be called a Wessel diagram is known instead as an Argand diagram after the man whose work on the same subject, published in 1806, first came to the attention of the mathematical world. Wessel's paper, by contrast, wasn't noticed by the mathematical community until 1895 when the Danish mathematician Sophus Juel drew attention to it and, in the same year, Sophus Lie

Extractions: Version for printing Caspar Wessel 's father, Jonas Wessel, and his grandfather were both ministers in the church. His mother, Helene Marie Schumacher and Jonas had a large family consisting of fourteen children; Caspar was the sixth of the fourteen. Caspar, together with his two elder brothers Johan Herman Wessel and Ole Christopher Wessel, attended Christiania Cathedral School in the city of Christiania from 1757 until 1763 (Christiania was later renamed Kristiania, then Oslo in 1925). Caspar could not attend university in Norway for, at that time, there were no Norwegian universities. Since Norway was united with Denmark, the natural place for Norwegians to go for a university education was Denmark, and Caspar's brothers Johan Herman and Ole Christopher were already at the University of Copenhagen, having entered in 1761. Caspar spent one year, from 1763 to 1764, studying at the University of Copenhagen but, as one might imagine, the large family was putting quite a strain on his parent's finances. As we shall see below, this led to both Caspar and his brother Ole Christopher obtaining positions as surveyors with the Royal Danish Academy of Sciences Ole Christopher and Caspar were studying at the University of Copenhagen for a law degree. Ole Christopher started to work as a surveyor to help pay his way through university while Caspar was still at school. Obtaining his law degree in 1770, Ole Christopher went on to reach a very elevated position in the legal profession in Norway. Johan Herman (three years older than Caspar) became a poet and is the only one of the Wessel children to have their own entry in

Extractions: Hjemmeside Sange Matematik ... Links KRONIKEN I POLITIKEN Torsdag 8. juni 1995 Af JØRGEN EBERT Den dansk-norske landmåler Caspar Wessel er mindre kendt end sin storebror Johan Herman. Men han opdagede grundlaget for moderne matematik. I dag fylder han 250 år. Jørgen Ebert er lektor, cand. scient. TALLENE er alle tings væsen, sagde Pythagoras. Han mente, at vejen til sjælens frigørelse lå i et studium af de talmæssige forhold, som gør naturen til et harmonisk kosmos. Selv om vi nu, omkring 2500 år senere, nok ikke ville udtrykke os helt på denne måde, må vi indrømme, at tallene spiller en væsentlig rolle for vores forståelse af verden. Og vi har opnået så stor fortrolighed med dem, at vi er tilbøjelige til at betragte dem som evige og naturgivne. Men den opfattelse er forkert. Ideen om tallene er skabt af mennesker, som gennem årtusinder har forbedret regnekunsten. Den mest betydningsfulde drivkraft har været de skiftende kulturers forsøg på at forklare naturens forskelligartede fænomener som for eksempel årstidernes rytme og månens bevægelser. Men også rent praktiske gøremål har inspireret. Oldtidsbonden har haft brug for at holde styr på antallet af husdyr, og søfareren behøvede en vis form for navigation. Alle disse aktiviteter involverede beregninger, som blev mere og mere avancerede i takt med naturvidenskabernes udvikling. Når kravene til tallenes anvendelighed steg, måtte man udvide og forbedre forældede talsystemer. Tallene bør derfor betragtes som en kulturel frembringelse, der har været undervejs, siden de første civilisationer opstod.

Extractions: Siste utgave Om fagbladet Redaksjonsarkiv ... Nettforum av Nils Voje Johansen Caspar Wessel (1745-1818) regnes som Norges første matematiker. I en avhandling som ble lest i Det kgl. danske Videnskabernes Selskab i 1797, gav Wessel som førstemann en geometrisk tolkning av de komplekse tall. Hele sitt yrkesaktive liv arbeidet han imidlertid som landmåler. De fleste forbinder Wesselnavnet med dikteren Johan Herman Wessel eller krigshelten Peter Wessel Tordenskiold. Den første var Caspar Wessels bror, den andre hans grandonkel. Caspar ble født i Vestby i Akershus. Den første undervisningen fikk han hjemme før han i 1757 ble innskrevet ved katedralskolen i Christiania sammen med sine to eldre brødre Johan Herman og Ole Christopher. Spesielt én lærer ser ut til å ha hatt stor betydning for unge Caspar. I voksen alder skrev han: Jeg kom i 4de Lektie, som den gang havde til Lærer Magister Bartholin, der siden blev Sekretær i Missionskollegiet. Ham skylder jeg meget; uanmodet gav han mig fri privat Undervisning, og hjalp mig dessuden til at Lære Tegning. I 1763 gikk turen til København Universitet hvor han valgte matematikeren og astronomen Horrebow til veileder. Kanskje viser dette at han allerede da hadde en spesiell interesse for realfag. Etter anneneksamen valgte Wessel imidlertid å studere jus, men ble snart opptatt med andre aktiviteter enn lovstudier.
