In 1867, J.B. Merwin, who had been connected with the Home and School Journal in Chicago, established the American Journal of Education, and has remained its editor and proprietor ever since. Mr. Merwin was associated with Horace Mann and Henry Barnard in establishing the school systems of Massachusetts and Connecticut. He made the American Journal of Education a progressive publication, and under his management it has largely contributed to building up the school system of the Southwest. The Journal of Education has a large circulation, and editions are printed for Missouri, Illinois and Wisconsin, Kansas and Colorado, Texas, Mississippi, Arkansas, and Tennessee. A specialty of the Journal of Education has been the publication of plans for schoolhouses, many of which have been adopted in the states mentioned.
