Henry Houghton originally started The Riverside Press in an old Cambridge building along the banks of the Charles River. A visitor described it as  one of the model printing-offices in America. Houghton chose to employ women as well as men as compositors, a radical decision which he said was influenced by the Victoria Press in England.

They soon established an educational department and quickly expanded the company's educational offerings. Modern era.
