Bernhardt "Ben" Klassen ((1918-02-20)February 20, 1918 (O.S. February 7, 1918) – (1993-08-06)August 6, 1993) was an American white supremacist politician who founded the Creativity new religious movement when he published his book Nature's Eternal Religion in 1973. Klassen was openly racist, antisemitic and anti-Christian and first popularized the term "Racial Holy War" within the White Power movement.

Klassen was a Republican Florida state legislator for several months, as well as a supporter of George Wallace's presidential campaign. In addition to his religious and political work, Klassen was an electrical engineer and he was also the inventor of a wall-mounted electric can-opener. Klassen held unorthodox views about dieting and health. He was a natural hygienist who opposed the germ theory of disease as well as conventional medicine and promoted a fruitarian, raw food diet.

Bernhardt Klassen was born on February 20, 1918, in Rudnerweide (now Rozivka in Chernihivka Raion in Zaporizhzhia Oblast), Ukraine, to Bernhard and Susanna Klassen (née Friesen) a Russian Mennonite Christian couple. He had two sisters and two brothers. When Klassen was nine months old, he caught typhoid fever and nearly died. Due to the Russian Civil War, circumstances during his early childhood were quite difficult. When he was five, the family moved to Mexico, where they lived for one year. In 1925, at age six, he moved with his family to Herschel, Saskatchewan, Canada. He attended the German-English Academy (now Rosthern Junior College).

Klassen established a real estate firm in Los Angeles in partnership with Ben Burke. Believing that his partner was prone to drinking and gambling, Klassen eventually bought him out and became sole proprietor. He hired several salesmen, including Merle Peek, who convinced him to buy large land development projects in Nevada. Klassen and Peek started a partnership called the Silver Springs Land Company, through which they founded the town of Silver Springs, Nevada. In 1952, Klassen sold his share of the company to Phillip Hess for $150,000 and retired.

On March 26, 1956, Klassen filed an application with the U.S. Patent Office to patent a wall-mounted, electric can opener which he marketed as Canolectric. In partnership with the marketing firm Robbins & Myers, Klassen created Klassen Enterprises, Inc. In the face of competition from larger manufacturers that could provide similar products more cheaply, Klassen and his partners dissolved the company in 1962.

Klassen served Broward County in the Florida House of Representatives from November 1966 – March 1967, running on an anti-busing, anti-government platform. He campaigned for election to the Florida Senate in 1967, but was defeated. That same year, he was vice chairman of an organization in Florida which supported George Wallace's presidential bid.

Klassen was a member of the John Birch Society, at one point operating an American Opinion bookstore, but became disillusioned with the Society because of what he viewed as its tolerant position towards Jews. In November 1970, Klassen, along with Austin Davis, created the Nationalist White Party. The party's platform was directed at White Christians and it was explicitly religious and racial in nature; the first sentence of the party's fourteen-point program is "We believe that the White Race was created in the Image of the Lord." The logo of the Nationalist White Party was a "W" with a crown and a halo over it, and it would be used three years later as the logo of the Church of the Creator.

Less than a year after he created the Nationalist White Party, Klassen began expressing apprehension about Christianity to his connections through letters. These letters were not well received, and they effectively ended the influence of the Nationalist White Party.
