Mr. Moquin’s first job for Encyclopaedia Britannica was as associate editor of the 20-volume set, Annals of America. After this he compiled and edited the materials to be included in the 10-volume Makers of America, documenting immigration and ethnicity in the United States from the 16th to the late 20th century. He then compiled and edited the materials for four one-volume books published by Praeger Publishers in New York. These were Documentary History of Mexican Americans, Great Documents in American Indian History (before they were called Native Americans), Documentary History of Italian Americans, and The American Way of Crime. In retirement he found another career as an indexer of textbooks in economics.
