From 1854 until 1858 the K.Valdemāra studied at Tartu University in the country and economic sciences. To their student's room door, he proudly fastened a business card with the note "Latvian". K.Valdemārs, the first of educated Latvians, openly acknowledged his nationality and recommended that he not be ashamed and not retreat from it. His calling card with the word "Latvian" was something unheard of at that time.
