Ben (Bernhardt) Klassen (1918 — 1993) was the main founder of the religion of Creativity. In 1973 he founded the original Church of the Creator (COTC) (not to be confused with the TE-TA-MA Truth Foundation - Family of URI Inc.'s Oregon-based group), which changed its name to the World Church of the Creator (WCOTC) in 1996 when Matt Hale was elected as its Pontifex Maximus, or Supreme Leader, and later to The Creativity Movement (TCM) in 2003 after a trademark dispute with the TE-TA-MA Truth Foundation - Family of URI® Inc. He attracted several hundred white supremacists as members from the US, Canada, Sweden, Ukraine, Russia, Poland, and South Africa.

Klassen first popularized the term Racial Holy War (RaHoWa) within white supremacism.

Klassen committed suicide in 1993 after the death of his wife, by overdosing on sleeping pills. In his suicide note, he made reference to his book The White Man's Bible, which describes suicide as "an honorable and dignified way to die for any ... of a number of reasons, such as having come to the decision that life is no longer worthwhile."

Klassen was the author of several books - Expanding Creativity (1985), The White Man's Bible (1986), A Revolution of Values Through Religion (1991) and Nature's Eternal Religion (1992).
