A New York farmer established the first cheese factory and revolutionized the industry

Jesse Williams, a farmer in New York state, had a passion for cheese but didn’t have the resources to produce it at the scale he desired. So, in 1851, Jesse and his son opened the first cheese factory, sourcing milk from multiple local farms and producing 100,000 pounds of cheddar—in their first season. Soon, Williams had hundreds of factories and created the prototype for cheesemaking as we know it today.

The hidden engineering of gas stations

Contemporary gas stations are the result of a century of engineering progress. In the early 1900s, only a few thousand cars drove around, and they used kerosene. As vehicles and cheaper gasoline became more popular, fire hazards grew, forcing the invention of fuel pumps, underground storage tanks, and the automatic shutoff valve—all engineering marvels.

The first American roller coaster was built at Coney Island
