- R. J. Rushdoony
Rev. R.J. Rushdoony (1916–2001), was a leading theologian, church/state expert, and author of numerous works on the application of Biblical law to society. He started the Chalcedon Foundation in 1965. His Institutes of Biblical Law (1973) began the contemporary theonomy movement which posits the validity of Biblical law as God’s standard of obedience for all. He therefore saw God’s law as the basis of the modern Christian response to the cultural decline, one he attributed to the church’s false view of God’s law being opposed to His grace. This broad Christian response he described as “Christian Reconstruction.” He is credited with igniting the modern Christian school and homeschooling movements in the mid to late 20th century. He also traveled extensively lecturing and serving as an expert witness in numerous court cases regarding religious liberty. Many ministry and educational efforts that continue today, took their philosophical and Biblical roots from his lectures and books.
- Otto Scott
Otto Scott (May 26, 1918—May 5, 2006), a former Chalcedon staffer, was a journalist, business executive, and historian. He began his newspaper career at the age of sixteen and later worked for United Features Syndicate and The San Diego Union. When WWII broke out he joined the Merchant Marine. After the war, Scott worked in the advertising industry, then became editor of a manufacturing trade journal, Rubber World. In the course of his assignments, he interviewed Paul Blazer, the chairman of Ashland Oil, in Ashland, Kentucky, and was invited to write the history of the company. He would later write corporate histories for Raytheon, Black & Decker, and Arch Mineral Corporation. After his conversion to Christianity, he focused on writing about modern history, politics, and cultural trends. In his later years, he worked for Chalcedon before publishing his own newsletter, The Compass.
- Samuel L. Blumenfeld
Samuel L. Blumenfeld (1927–2015), a former Chalcedon staffer, authored a number of books on education, including NEA: Trojan Horse in American Education, How to Tutor, Alpha-Phonics: A Primer for Beginning Readers, and Homeschooling: A Parent’s Guide to Teaching Children.
He spent much of his career investigating the decline in American literacy, the reasons for the high rate of learning disabilities in American children, the reasons behind the American educational establishment’s support for sex and drug education, and the school system's refusal to use either intensive phonics in reading instruction and memorization in mathematics instruction. He lectured extensively in the U.S. and abroad and was internationally recognized as an expert in intensive, systematic phonics. His writings appeared in such diverse publications as Home School Digest, Reason, Education Digest, Boston Magazine, Vital Speeches of the Day, Practical Homeschooling, Esquire, and many others.
