Don't eat hamburgers unless you're aware of this. 

The history of hamburgers can be traced back to the late 19th century in the United States. This dish consisted of a beef patty that was seasoned and served between two slices of bread. Sometimes later, because of German immigrants, burgers became a famous food in the USA. The first recorded instance of a burger served on a bun was at the World's Columbian Exposition in Chicago in 1893. The dish was served by a vendor named Charles Noreen, who is now considered the "father of the hamburger."

In the early 20th century, the popularity of burgers continued to grow as they became a staple of American fast food culture. The first chain of burger restaurants, White Castle, was established in 1921, and the first drive-in restaurant, In-N-Out Burger, was opened in 1948.

 

The popularity of burgers also spread internationally in the mid-20th century, with the expansion of American fast food chains like McDonald's, Burger King, and Wendy's. These chains revolutionized the fast food industry by introducing the concept of mass-produced, standardized burgers that could be made quickly and sold at a low cost.

However, the rise of fast food also led to concerns about the quality of burgers, as the mass-production process often involved the use of low-quality ingredients and preservatives. In response, a growing movement of "gourmet" burger restaurants emerged in the late 20th and early 21st centuries, offering burgers made with high-quality, locally sourced ingredients and unique flavor combinations.

Today, burgers remain one of the most popular foods in the world, with a vast array of options available to suit different tastes and dietary restrictions. From classic fast food chains to gourmet restaurants, burgers have come a long way from their humble origins as a simple beef patty on a bun.

In conclusion, the birth of burgers can be traced back to the late 19th century in the United States, where the Hamburg steak dish was introduced by German immigrants. The dish evolved over the years, becoming a staple of American fast food culture in the 20th century and a popular food worldwide today. Despite concerns about the quality of mass-produced burgers, the rise of gourmet burger restaurants has ensured that this classic dish continues to thrive in the modern era.
