Johan Henrik Burmester (1720-1770) Tillbaka Anders Celsius (1701-1744) Anders Celsius behöver egentligen ingen närmare presentation. Redan 1710 blev han inskriven vid Uppsala Universitet. Från början läste Celsius juridik men växlade snart över till naturvetenskapen. Celsius läste matematik för Anders Gabriel Duhre och fick snart även börja undervisa hos honom. År 1727 utgav Celsius läroboken "Aritmetika eller Ränekonst". I "Observationer om tvenne beständiga grader på en thermometer" (1742) visar Celsius att snöns smältpunkt alltid infaller vid samma temperatur oberoende av tryck, och presenterade den 100 gradiga skalan. Anders Celsius: Professor i Uppsala 1701-1744 (Uppsala 1936) och Sten Lindhrots (Stockholm 1989)] Tillbaka Anders von Drake (1682-1744) KVA såg i Drake en begåvad, oegennyttig man med "lätt och förnöjt" sinne. Herr Presidentens von Drakes Minne (KVA 1745:68)] Tillbaka Samuel Duraeus (1718-1789) Tillbaka Per Elvius (1710-1749) Elvius kompetens inom flera vetenskaper har diskuterats, men en konst han definitivt inte hade fallenhet för var talarkonsten. Åhörarna till hans Thamiska föreläsningar upphörde att komma och hans undervisningsskyldighet omvandlades snart till en serie artiklar i KVA. Härav uppkom den intressanta följetongen "Vetenskapernas Historia".

Anders Lexell, among others (including Herschel), calculates the orbit of the moving body discovered by Herschel, establishing that it is a new planet. Herschel originally proposes the name Georgium Sidus for the new planet (after England's King George III), but the international astronomical community, maintaining the old tradition of naming planets after the gods of Antiquity, settles on the name Uranus.
