From 1837 to 1840 Herford studied at Manchester College, York, and while there came into contact with German philosophy and theology. He moved with the college from York to Manchester in the summer of 1840, and thus came under the influence of three new professors, Francis Newman, James Martineau, and John James Tayler, the last of whom he regarded as his "spiritual father". Graduating B.A. of London University in the autumn of 1840, he began to preach in Unitarian pulpits, but declined a permanent engagement as minister at Lancaster in order to accept a scholarship for three years' study in Germany. In 1842 Herford went to Bonn University, where he attended the courses of Ernst Moritz Arndt, August Wilhelm Schlegel, and Friedrich Christoph Dahlmann, and formed a close friendship with his contemporary Wilhelm Ihne. After two years there he spent eight months in Berlin, where he was admitted to the family circles of August Neander and Christian Gottfried Ehrenberg. In the summer of 1845 he accepted an invitation from a Unitarian congregation at Lancaster, where he remained a year. In 1846 Lady Byron invited Herford, on James Martineau's recommendation, to undertake the tuition of Ralph King, younger son of her daughter, Ada, Countess of Lovelace. Herford, early in 1847, accompanied the boy to Wilhelm von Fellenberg's Pestalozzian school at Hofwyl, near Berne. Herford grew close to von Fellenberg, became a temporary teacher on the staff, and took to Pestalozzi's and Froebel's educational ideas.
Educator
In February 1848 Herford resumed his pastorate at Lancaster, deciding also to work out in a systematic way educational ideas which he had developed at Hofwyl. In January 1850, while retaining his ministerial duties, he opened at Lancaster a school for boys on Pestalozzian principles. It continued for 11 years, when a decline in its numbers caused him to transfer it to other hands. Resigning his pastorate at the same time, Herford with his family went for eighteen months to Zurich in charge of a pupil. On his return in September 1863, he filled the pulpit of the Free Church in Manchester until 1869, acquiring a reputation as a teacher and lecturer, especially to women and girls: he was an advocate of the opening of universities to women. Some of his teaching was given at Brooke House School, Knutsford, whose headmistress, Louisa Carbutt, was educating girls on principles similar to his own. Herford then formed a plan of a co-educational school for younger children. In 1873 he opened his co-educational school at Fallowfield, Manchester, and then moved it to Ladybarn House, Withington, as Lady Barn House School. For 12 years he ran it in an individual style. Resigning the school to his second daughter in 1886, he concentrated on writing and travel.
Herford published in 1889 his major work The School: an Essay towards Humane Education, based on his teaching experience. In 1893 he published The Student's Froebel, adapted from Die Menschenerziehung of Friedrich Fröbel. In 1902 he published Passages from the Life of an Educational Free Lance, a translation of the Aus dem Leben eines freien Pädagogen of Dr. Ewald Haufe.
