As Chancellor for the Universities of Uppsala and Lund, what did De Geer promote?

Context:
In 1876 De Geer became the first Prime Minister of Sweden following a reform where the previous offices of Prime Minister for Justice (which he held at the time) and Prime Minister for Foreign Affairs were changed into Minister for Justice and a Minister for Foreign Affairs. He served until April 1880, when the failure of his repeated efforts to settle the armaments issue again induced him to resign. From 1881 to 1888 he was Chancellor for the Universities of Uppsala and Lund. He was an advocate of free trade and economic liberalism. Some argue that it was De Geer who laid the foundations for the strong economic growth in Sweden from 1870 to 1970.<|im_end|>
