John Glen Sperling (January 9, 1921 – August 22, 2014) was an American billionaire businessman who is credited with having led the contemporary for-profit education movement in the United States[1] The fortune he amassed was based on his founding of the for-profit University of Phoenix for working adults in 1976, which became part of the publicly traded Apollo Group. Sperling brought the business model of higher education to the forefront, a model that employed the scientific management of higher education to the forefront: diminishing the power and importance of labor, increasing the importance of technology, marketing and advertising, and as University of Phoenix cofounder John D. Murphy explained, maximizing profit.[2] For ventures ranging from pet cloning to green energy, he has widely been described as an "eccentric" self-made man by The Washington Post and other media.[3][4]
