=As Teacher.=--Meeting with little success in various enterprises in which he engaged, he at last drifted to Frankfurt-am-Main, where he made the acquaintance of Dr. Gruner, head master of the Model School. Dr. Gruner quickly discovered Froebel's talent, and urged him to accept a position under him as teacher. Froebel reluctantly consented, but in speaking later of his first experience in the schoolroom, he says, "It seemed as if I had found something I had never known, but always longed for, always missed; as if my life had at last discovered its native element. I felt as happy as the fish in the water, the bird in the air." Although Froebel succeeded at once in his new profession, thereby justifying Dr. Gruner's opinion of him, he felt that he needed special preparation for the work of teaching. Accordingly, in 1808, after two years' experience in teaching, having in the meantime visited Pestalozzi at Yverdon, and having read his works, he gave up his position and joined the institute at Yverdon. He took with him three of his pupils to tutor, and "it thus happened," he tells us, "that I was there both as teacher and scholar, educator and pupil." Froebel spent two years at Yverdon, and his testimony concerning Pestalozzi is interesting. He says, "He set one's soul on fire for a higher and nobler life, though he had not made clear or sure the exact road toward it, nor indicated the means whereby to attain it." This sums up in a word the secret and extent of Pestalozzi's power. Dittes thinks that "the origin of the kindergarten is due to the pedagogical revival of Pestalozzi." Froebel himself, speaking of his experience at Yverdon, says, "I studied the boys' play, the whole series of games in the open air, and learned to recognize their mighty power to awaken and to strengthen the intelligence and the soul as well as the body." Here we find the first suggestion of the kindergarten, which has made Froebel famous. After leaving Yverdon, Froebel spent about two years at the universities of Goettingen and Berlin in furthering his preparation for educational reform, to which he had devoted himself. In 1813 war for German liberty broke out, and Froebel, with many other students, enlisted. It is not the purpose here to follow his fortunes as a soldier, but while in the army he made the acquaintance of two young men who afterward became associated with him in educational enterprise,--Wilhelm Middendorff and Heinrich Langethal.
