McDonald's

McDonald's is the world's largest chain of hamburger fast food restaurants, serving around 68 million customers daily in 119 countries across more than 36,000 outlets. Founded in the United States in 1940, the company began as a barbecue restaurant operated by Richard and Maurice McDonald. In 1948, they reorganized their business as a hamburger stand using production line principles. Businessman Ray Kroc joined the company as a franchise agent in 1955. He subsequently purchased the chain from the McDonald brothers and oversaw its worldwide growth.

MacDonald, Macdonald, and McDonald are Anglicised forms of the Scottish Gaelic and Irish Gaelic name MacDhòmhnaill, which in modern Gaelic is approximated as McConnell. It is a patronym where Mac means "son" and Dhòmhnaill means "of Dòmhnall". The personal name Dòmhnall is composed of the elements domno "world" and val "might", "rule". According to Alex Woolf, the Gaelic personal name is probably a borrowing from the British Dyfnwal.
