Louisa Ulrika was received with enthusiasm in Sweden as the hope for the salvation of succession crisis. At the birth of her first child in 1745, no children had been born in the Swedish royal house in over 50 years and she gained initial popularity with her beauty, wit and interest in science and culture. Carl Gustaf Tessin described her as "the wisdom of a god in the image of an angel",. Despite French being her native language, she was tutored in Swedish by Carl Jesper Benzelius and mastered it well after only two years. She studied Swedish literature and gathered a Swedish language library, she corresponded with the Royal Swedish Academy of Sciences and created a nature scientific collection. Her arrogant and haughty demeanor, however, eventually made her less popular outside of the royal court.
