Which McDonald's training institution opened in 1961 at the company's Illinois headquarters?

Hamburger University opened in 1961 at McDonald's headquarters in Oak Brook, Illinois.

The institution was created to train restaurant managers and owner-operators in McDonald's operating standards, service methods, quality control, and procedures. Although its name sounds playful, it became a serious part of the company's corporate culture and brand consistency.

Training helped McDonald's deliver a similar customer experience across restaurants operated by different franchisees. That consistency supported the company's visual identity, menu presentation, service style, and broader branding.

Hamburger University is not the name of a restaurant concept or a school for culinary degrees. It is McDonald's internal training center, and the company later established additional training facilities in other countries.
