McDonald's Corporation is the world's largest chain of fast-food restaurants, primarily selling hamburgers, chicken, french fries, breakfasts and soft drinks. More recently, it also offers salads, fruit, snack wraps, and carrot sticks. The business began in 1940, with a restaurant opened by siblings Dick and Mac McDonald in San Bernardino, California. Their introduction of the "Speedee Service System" in 1948 established the principles of the modern fast-food restaurant. The present corporation dates its founding to the opening of a franchised restaurant by Ray Kroc, in Des Plaines, Illinois on April 15, 1955, the ninth McDonald's restaurant overall. Kroc later purchased the McDonald brothers' equity in the company and led its worldwide expansion.

With the successful expansion of McDonald's into many international markets, the company has become a symbol of globalization and the spread of the American way of life. Its prominence has also made it a frequent subject of public debates about obesity, corporate ethics and consumer responsibility. (less)

The first permanent photograph was made in 1826 or 1827 by Joseph Nicéphore Niépce using a sliding wooden box camera made by Charles and Vincent Chevalier in Paris. Niépce built on a discovery by Johann Heinrich Schultz (1724): a silver and chalk mixture darkens under exposure to light. While this was the introduction of photography, the history of the camera can be traced back much further. Photographic cameras were a development of the camera obscura, a device dating back to the Book of Optics (1021) of the Iraqi Arab scientist Ibn al-Haytham (Alhacen), which uses a pinhole or lens to project an image of the scene outside onto a viewing surface.

Before the invention of photographic lapel processes there was no way to preserve the images produced by these cameras apart from manually tracing them. The earliest cameras were room-sized, with space for one or more people inside; these gradually evolved into more and more compact models such that by Niépce's time portable handheld cameras suitable for photography were readily available. The first camera that was small and portable enough to be practical for photography was built by Johann Zahn in 1685, though it would be almost 150 years before such an application was possible.
