Former President Gerald Ford and Gov. Norm Bangerter are among a host of dignitaries and business executives who will help observe the 100th anniversary of the American Express Traveler's Cheque Friday night at the company's operations center in West Valley City.

Best known for its commercial slogan "Don't leave home without it," the product was created in April 1891 by a company employee who developed the traveler's check to help stem his boss's difficulties in converting letters of credit to cash while traveling abroad.American Express' 1990 sales of Traveler's Cheques worldwide was $25.3 billion.

The company opened its worldwide operations center in West Valley City in October 1982, said spokesman Mark Day. The center employs about 2,000 people.
