After publishing a popular self-help book titled Finding the Love of Your Life, this theologian, psychologist, author, and motivational speaker created the famous eHarmony dating website.
After receiving his bachelor's degree from Pepperdine University, he attended the Princeton Theological Seminary and went on to earn a doctorate in psychology from the University of Chicago.
He spurred controversy by not allowing same-sex matches on his eHarmony site.
His marriage to Marylyn Warren resulted in three children. In the mid-1990s, he and his son-in-law, Greg Forgatch, established a company called Neil Clark Warren & Associates that was later renamed eHarmony.
He and Gary Chapman both penned Christianity and relationship-themed self-help books.
