Andrew Schlafly is the fifth child of attorney John Fred Schlafly, Jr. and noted political activist Phyllis Schlafly. His great-grandfather, August Schlafly, was founder of the Union Trust and Savings Bank of East St. Louis, Ill., the First National Bank of Edwardsville, Ill., and other banks in Western states. 
He graduated from Princeton University with a bachelor's degree in Electrical Engineering and Computer Science. A magna cum laude graduate from Harvard Law School, he was an editor of the Harvard Law Review. 
Conservapedia developed as a result of his World History course. Andrew Schlafly and several of his top students continue to lead the project, and most of his students have contributed entries to it.
Andrew Schlafly has taught homeschoolers online since the late 1990s, and in person since fall 2002. Several of Andrew Schlafly's prior course materials are available on Eagle Forum University.
