John H. Saxon Jr. was a U.S. air officer and educator. Saxon flew 55 missions in a B-26 Night Intruder during the Korean War. After the war, he wrote a series of mathematics textbooks (such as ones for arithmetic, algebra, and calculus) which use an incremental teaching method often called "Saxon math". His books have gained popularity among certain "traditionally"-oriented groups of homeschoolers and private schools, but are also used in a number of public schools. Wikipedia
