Robert Harold Schuller is an American televangelist, pastor, and author known around the world through his weekly Hour of Power television broadcast. He is the founder of the Crystal Cathedral in Garden Grove, California, where the Hour of Power program originates.

Schuller was born a few miles outside of Alton, Iowa to a family of Dutch ancestry and, after finishing his studies at Hope College and Western Theological Seminary, was ordained as a minister in the Reformed Church in America.

Strongly influenced by his mentor, Norman Vincent Peale, Schuller has chosen to focus on what he believes are the positive aspects of the Christian faith. He deliberately avoids condemning people for sin, and he encourages Christians (and non-Christians) to achieve great things through God, uplifting theology and positive thinking.
