When I entered it, though at that time it was much modified and established on firm foundations, I met with a similar experience. It was not only the open air, the forest, the life in Nature which so captivated new arrivals at Keilhau, but the moral earnestness and the ideal aspiration which consecrated and ennobled life. Then, too, there was that "nerve-strengthening" patriotism which pervaded everything, filling the place of the superficial philanthropy of the Basedow system of education. But Froebel's influence was soon to draw, as if by magnetic power, the man who had formed an alliance with him amid blood and steel, and who was destined to lend the right solidity to the newly erected structure of the institute--I mean Heinrich Langethal, the most beloved and influential of my teachers, who stood beside Froebel's inspiring genius and Middendorf's lovable warmth of feeling as the character, and at the same time the fully developed and trained intellect, whose guidance was so necessary to the institute. The life of this rare teacher can be followed step by step from the first years of his childhood in his autobiography and many other documents, but I can only attempt here to sketch in broad outlines the character of the man whose influence upon my whole inner life has been, up to the present hour, a decisive one. The recollection of him makes me inclined to agree with the opinion to which a noble lady sought to convert me--namely, that our lives are far more frequently directed into a certain channel by the influence of an unusual personality than by events, experiences, or individual reflections.
