MCH was founded in 1928 by noted educator Dr. Forrest E. Long. Dr. Long was a Professor of Education at New York University. He was also an author, editor, publisher, administrator, and innovator. While at NYU, he became the editor and publisher of Junior High Clearing House, an educational journal for secondary schools. The focus of the journal was to be a “clearing house” of ideas and research about the new “junior high school” as grades six through nine were known at that time.
Distribution of Junior High Clearing House to secondary school principals soon evolved into the first commercial school mailing list and became the forerunner of today’s educational mailing list industry. Before the age of computers, the mailing lists were maintained mechanically on addressograph plates. By the early 1930s, the New York City office in Rockefeller Center became too small, and a branch office was opened in Sweet Springs, Missouri, Dr. Long’s birthplace.
In addition to being a journal publisher and mailing list and mailing services supplier, the company was also a book publisher under the names Inor Publishing and Roxbury Press. In the 1930s, the company’s Inor Guidance Series by Richard D. Allen became the national best seller in books for high school guidance counselors. The company pioneered when it published Sex Education as Human Relations by Lester Kirkendahl, which was recognized as the first textbook that dared to consider sex education as a topic of possible interest to schools.
