What was McDonald's corporate name when it was incorporated in 1955?

McDonald's corporate name when it was incorporated in 1955 was McDonald's System, Inc.

The company was incorporated by Ray Kroc in 1955 as he developed the franchise system based on the McDonald brothers' restaurant model. The name emphasized an organized operating system rather than only a single restaurant or family business.

McDonald's System, Inc. later became McDonald's Corporation, the name most associated with the public company and global brand. The corporate-name change belongs to the company's later development and should not be projected backward onto the 1955 incorporation.

This distinction matters because the McDonald brothers had operated their own restaurant business before Kroc's corporate expansion. The 1955 incorporation marked a major step in creating the franchising organization that would build the modern McDonald's brand.
