Albert Einstein’s letter to Adolf Marx, dated April 1, 1934, is an exceptional document that connects Catalonia with one of the most relevant figures in European and world science. Written in a context of growing fascist threat, this correspondence reflects Einstein’s commitment to freedom, reason and human dignity. The fact that this document is preserved in a Catalan archive reinforces the idea of \u200b\u200bCatalonia as a place of welcome, culture and memory. It is also an example of how archives can guard not only local history, but also essential fragments of universal history. This letter reminds us that science and critical thinking are fundamental pillars of European civilization.<\/p>\n","protected":false},"featured_media":14702,"template":"","meta":{"_acf_changed":false,"inline_featured_image":false},"eix":[],"class_list":["post-10511","document","type-document","status-publish","has-post-thumbnail","hentry"],"acf":[],"yoast_head":"\nLetter from Albert Einstein to Adolf Marx (1\/4\/1934) - Catalunya Pa\u00eds d'Arxius<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/catalunyapaisdarxius.cat\/en\/catalunyapaisdarxius\/digital-resource\/resource\/document\/carta-dalbert-einstein-a-adolf-marx-1-4-1934\/\" \/>\n<meta property=\"og:locale\" content=\"en_US\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Letter from Albert Einstein to Adolf Marx (1\/4\/1934) - Catalunya Pa\u00eds d'Arxius\" \/>\n<meta property=\"og:description\" content=\"Albert Einstein’s letter to Adolf Marx, dated April 1, 1934, is an exceptional document that connects Catalonia with one of the most relevant figures in European and world science.
