The conflict dragged on as the Russians were as poorly prepared as their opponents. The Prime Minister, Lord Aberdeen, resigned and Palmerston succeeded him. A negotiated settlement eventually put an end to the war with the Treaty of Paris. During the war, Albert arranged the marriage of his fourteen-year-old daughter, Victoria, to Prince Frederick William of Prussia, though Albert delayed the marriage until Victoria was seventeen. Albert hoped that his daughter and son-in-law would be a liberalising influence in the enlarging but very conservative Prussian state. Albert promoted many public educational institutions. Chiefly at meetings in connection with these he spoke of the need for better schooling. A collection of his speeches was published in 1857. Recognised as a supporter of education and technological progress, he was invited to speak at scientific meetings, such as the memorable address he delivered as president of the British Association for the Advancement of Science when it met at Aberdeen in 1859. His espousal of science met with clerical opposition; he and Palmerston unsuccessfully recommended a knighthood for Charles Darwin, after the publication of "On the Origin of Species", which was opposed by the Bishop of Oxford. Albert continued to devote himself to the education of his family and the management of the royal household. His children's governess, Lady Lyttelton, thought him unusually kind and patient, and described him joining in family games with enthusiasm. He felt keenly the departure of his eldest daughter for Prussia when she married her fiancé at the beginning of 1858, and was disappointed that his eldest son, the Prince of Wales, did not respond well to the intense educational programme that Albert had designed for him. At the age of seven, the Prince of Wales was expected to take six hours of instruction, including an hour of German and an hour of French every day. When the Prince of Wales failed at his lessons, Albert caned him. Corporal punishment was common at the time, and was not thought unduly harsh. Albert's biographer Roger Fulford wrote that the relationships between the family members were "friendly, affectionate and normal ... there is no evidence either in the Royal Archives or in the printed authorities to justify the belief that the relations between the Prince and his eldest son were other than deeply affectionate." Philip Magnus wrote in his biography of Albert's eldest son that Albert "tried to treat his children as equals; and they were able to penetrate his stiffness and reserve because they realised instinctively not only that he loved them but that he enjoyed and needed their company."
