A Deep Dive into the World of Burgers

May is celebrated as National Hamburger Month, which started in 1993 thanks to the creative efforts of the White Castle restaurant chain. The best way to mark the occasion is by enjoying a hamburger. You can either cook one at home or visit a nearby burger place, since burgers are hugely popular worldwide. As mentioned by Maggie Hennessy in her book “Hamburger Bible,” a staggering 60% of all sandwiches consumed globally are burgers. The United States alone boasts roughly 84,000 establishments dedicated to this beloved food item, highlighting its widespread appeal.

Maggie Hennessy, a prolific freelance writer, contributes to various publications including WBEZ/Sun-Times. Hennessy has an interesting background, having grown up in Hershey, Pennsylvania, where her father worked for the Hershey Company. This made her a favorite among friends, especially around Halloween. Later, her family moved to Western Springs, and she graduated with a journalism degree from the University of Wisconsin-Madison.

Hennessy’s career has allowed her to explore many topics, with a focus on food, drinks, and the people behind them. She worked as a critic for Timeout Chicago and earned a professional cookery certificate from Kendall College. Her book on burgers materialized when Welbeck Publishing Group approached her with an offer. Despite a tight nine-month deadline, she delivered an engaging volume filled with information on 80 burger joints, ranging from local favorites to those as far as Dubai and Bangkok. The book not only explores burger history and includes recipes, but it also delights with its vibrant photos and playful tone.

In her book, Hennessy acknowledges fellow food writers, with a special mention of George Motz, known as Mr. “Hamburger America.” Motz has made a notable impact in the burger world, starting with his 2004 documentary “Hamburger America.” This was followed by a state-by-state guide to great burger spots, a Travel Channel show, and even his own restaurant in New York City, all under the “Hamburger America” brand. His latest book edition highlights 200 notable burger places across 452 pages, while lamenting the closures of some old favorites.

Both Hennessy and Motz’s works delve into why burgers are so universally loved. As Hennessy points out, burgers are affordable, fast, and filling. They also connect us to a primal desire for fire-cooked food. Motz encourages his readers to indulge in these tasty treats, appreciating the history of each dining experience. His sentiment that burgers are deeply enjoyable is echoed by many, including within the pages of Hennessy’s and his own books.

Among these iconic burger places is the Billy Goat in Chicago, known for its long history and millions of burgers served. The recent passing of Sam Sianis, the iconic owner, evokes nostalgia. When asked why burgers are so popular, Sam Sianis remarked simply, “The people like them because they’re good.” It’s a sentiment that resonates with the many who have enjoyed a burger at the Billy Goat under Michigan Avenue.
