She was the daughter of count Arvid Wittenberg and Eva Margareta von Langen, and married riksråd baron Henrik Horn in 1674.
In 1675, her spouse assigned her with a diplomatic mission to Hamburg. Her task was to secure the link between Sweden and its diplomats in Paris and London in connection to ongoing transfer of funds, and to secure the food-transport to the city of Stade, which was not yet conquered by Sweden and at the time besieged by Horn and the Swedish army. Reportedly, she developed "an activity worthy of respect on this post and managed to secure both funds and supplies to the disposition of her spouse".
She was widowed in 1693.
During Hedvig Sophia"s stay in Gottorp, Frederick regularly visited his lovers in Hamburg and also brought some of them to Gottorp. Wittenberg took the side of Hedvig Sophia and became involved in a physical argument with a male courtier who acted as the pimp of Frederick, an argument which ended with Wittenberg losing her wig and Hedvig Sophia"s demand to return to Sweden.
