Baroness Lehzen was a woman of sound knowledge and an important person of reference for Victoria, particularly since there were no children of her own age there when she was growing up. Victoria's mother expressed herself positively about the success of her education: "Her distinguishing trait," she was able to say about the fifteen year old, "is her good judgement, which allows her to teach herself with ease and to arrive quickly at a judicious and advantageous decision on every question about which she should express an opinion. Her love of truth is so marked that I am not concerned that this bulwark could be destroyed through any circumstances." Shortly before Victoria’s accession to the throne her uncle Leopold sent her his former personal physician in Coburg and then private secretary in Brussels, the liberal-minded Baron Christian Friedrich von Stockmar, who was to become an important adviser to Victoria and her husband for many years. His son would later take over the same position of trust with their daughter when she married and went to Prussia.
