Although knowledge about geomagnetism was old, only in the nineteenth century was it possible to improve precision measurements of magnetic intensity. After Carl Friedrich Gauss (1777-1855) established an international Magnetic Union (Magnetische Verein) based in G\u00f6ttingen in 1836, a network of magnetic observatories promoted a worldwide collaboration in order to get a deeper understanding of Earth's magnetism. While the participation of England, Russia, and the United States in this network is better known, Portugal also participated in this Union. This article aims to show how Portuguese institutions were influenced by the development of this branch of science and to detail their participation in the international geomagnetic network in the nineteenth century.<\/jats:p>","DOI":"10.17704\/eshi.24.1.y7250t05306q7215","type":"journal-article","created":{"date-parts":[[2015,4,30]],"date-time":"2015-04-30T16:11:06Z","timestamp":1430410266000},"page":"113-126","source":"Crossref","is-referenced-by-count":1,"title":["The Genesis of Geomagnetic Observatories in Portugal"],"prefix":"10.17704","volume":"24","author":[{"given":"Isabel","family":"Malaquias","sequence":"first","affiliation":[{"name":"Departamento de F\u00edsica, Universidade de Aveiro, 3810-193 Aveiro, Portugal"}]},{"given":"Em\u00edlia","family":"Vaz Gomes","sequence":"additional","affiliation":[{"name":"Departamento de F\u00edsica, Universidade de Aveiro, 3810-193 Aveiro, Portugal"}]},{"given":"D\u00e9cio","family":"Martins","sequence":"additional","affiliation":[{"name":"Departamento de F\u00edsica, Universidade de Coimbra, 3000 Coimbra, Portugal"}]}],"member":"7294","reference":[{"key":"2020060503405738500_"},{"key":"2020060503405738500_"},{"key":"2020060503405738500_"},{"key":"2020060503405738500_"},{"key":"2020060503405738500_"},{"key":"2020060503405738500_"},{"key":"2020060503405738500_"},{"key":"2020060503405738500_"},{"key":"2020060503405738500_"},{"key":"2020060503405738500_"},{"key":"2020060503405738500_"},{"key":"2020060503405738500_"},{"key":"2020060503405738500_"},{"key":"2020060503405738500_"},{"key":"2020060503405738500_","unstructured":"Escola Polit\u00e9cnica de Lisboa, Documentos comprovativos dos Direitos da Escola Polytechnica sobre o Observat\u00f3rio Meteorol\u00f3gico do Infante D.
