ABSTRACT Johan Gadolin (1760-1852), considered the father of Finnish chemistry, was one of the leading chemists of the second half of the 18th century and the first half of the 19th century. His life and scientific achievements were described in the literature published between the 19th and 21st centuries. The purpose of this paper is to familiarize readers with the important events in the life of Gadolin and his research activities, in particular some of his research results, as well as his selected publications. In addition, the names of authors of biographical notes or biographies about Gadolin, published in 1839-2017 are presented. Keywords: J.

Ångströmlaboratoriet Uppsala Universitet [KEMIVANDRING ‐ UPPSALA] Uppsala universitet: kort historik[Karta: 1‐4] Uppsala universitet grundades 1477 av katolska kyrkan som utbildningsinstitution för präster och teologer. Det är nordens äldsta universitet och var vid tidpunkten världens nordligaste universitet. Domkyrkorna utbildade präster men för högre utbildningar var svenskar från 1200‐ talet och framåt tvungna att studera vid utländska universitet i till exempel Paris eller Rostock. Den starkast drivande kraften för bildandet av Uppsala universitet var Jakob Ulvsson som var Sveriges ärkebiskop mellan år 1469‐1515 och därmed den som innehaft ämbetet längst (46 år). Vid domkyrkan mot riddartorget finns en staty av Jakob Ulvsson av konstnären och skulptören Christian Eriksson. Statyns porträttlikhet med Ulvsson är förstås tvivelaktig eftersom man inte vet hur Jakob Ulvsson såg ut. Konstnären studerade i Paris tillsammans med Nathan Söderblom och det sägs att Eriksson hade honom som förebild för Ulvsson statyn och som därmed fick mycket lika ansiktsdrag som Söderblom. (Nathan Söderblom var ärkebiskop i Uppsala 1914‐ 1931, grundade den Ekumeniska rörelsen och fick Nobels fredspris 1930). Till en början bestod undervisningen vid Uppsala universitet främst av filosofi, juridik och teologi. Någon teknisk eller naturvetenskap utbildning fanns inte vid denna tidpunkt. -

Astrid Cleve Von Euler Född 11 Januari 1875, Död 8 April 1968, Dotter Till Professor (Uppsala) Per Teodor Cleve Och Författaren Caralma Öhbom
Sveriges första kvinnliga doktor i naturvetenskapliga ämnen var lärare på Norra Real 1912-16 Astrid Cleve von Euler född 11 januari 1875, död 8 april 1968, dotter till professor (Uppsala) Per Teodor Cleve och författaren Caralma Öhbom. Disputerade i botanik den 27 maj 1898 vid Uppsala universitet. Astrid Cleve utbildade sig till botanist och blev fil. kand. 1894 och disputerade i Uppsala 1898. Hon var därmed den tredje kvinnan i Sverige som disputerade. (Ellen Fries var den första kvinnan som doktorerade, 1883 i historia). Hon var starkt målinriktad på att bli forskare men när hon som kvinna inte accepterades som sådan, blev hon lärare istället. Hon fick mycket goda betyg i undervisningsskicklighet och därmed tjänst som lärare på Norra Real. Naturligtvis inte som lektor på gymnasiet - kvinnor kunde inte få sådan tjänst - men genom sin kompetens kom hon ändå att vikariera som lektor med en lön som så småningom blev 75,9 procent av vad hennes manliga kolleger fick. Lönefrågan diskuterades i många instanser innan den här procentsatsen fastställdes. Man var helt enkelt rädd att statuera exempel. ”... doktor Cleve von Euler gjorda framställningen knappast lärer kunna anses vara prejudicerande i avseende å kvinnors anställning i statstjänst. Ett dylikt bifall kommer framför allt ej att beröra det mycket omstridda spörsmålet om kvinnas lämplighet eller icke såsom undervisare för manliga lärjungar å högre stadium, ...” Astrid Cleve gifte sig den 2 september 1902 med Hans von Euler, som 1929 skulle få nobelpriset i kemi. Han var invandrare från Tyskland, men hade då bott i Sverige tillräckligt länge - och var av ”god frejd” - för att få gifta sig här. -
