Melvin Nolan Freeman Gabler (January 5, 1915 - December 19, 2004) and his wife, Norma Elizabeth Rhodes Gabler (June 16, 1923 - July 22, 2007) were campaigners against public school textbooks which they regarded as "anti-family" or "anti-Christian".
The couple began their work in 1961 at their kitchen table in Hawkins, a small town in Wood County in northeastern Texas, after they claimed to have uncovered numerous errors in a son's history text. They established the nonprofit organization, Educational Research Analysts, a conservative Christian interest group based in Longview, the seat of Gregg County in east Texas.
Educational Research Analysts claims to uncover factual errors and examples of secular humanism, or the censorship of conservative political or social views in textbooks. Neal Frey, who worked with the Gablers since 1972 and now runs the organization, said that the Gablers' network of national supporters was invaluable to the cause. The organization has had national impact because Texas is second to California in population and is one of twenty-two states with a textbook-approval process which influences decisions made by other smaller states.
