Who Invented Deep Dish Pizza?

April 5 is National Deep Dish Pizza Day. Although some months have passed, you don't need an excuse to indulge in one of Chicago’s favorite foods. But who came up with the idea, anyway? 

Unfortunately, there is no official documentation about the original inventor of the delicacy, so the origin story is largely speculation. What we do know for sure is that the Chicago chain Pizzeria Uno plays an integral part in the story. According to the Chicago Tribune, following a paper trail about the pie's creation leads you back to a 19th century mansion on 29 E. Ohio St. The mansion is now home to Pizzeria Uno. 

Business partners and mansion residents Ike Sewell and Ric Riccardo wanted to open a restaurant. Their first idea was a Mexican establishment, but the trial runs left Riccardo physically ill. Riccardo was Italian, so the duo decided to make pizza their plan B. 

Originally called The Pizzeria, their restaurant opened in 1943 and wanted to serve an Americanized version of pizza that was unique to Chicago. The result was a thick, cake-like pizza pie with gooey cheese and sausage in its center, and sauce on top. 

Of course, Chicagoans had been eating pizza before the birth of deep dish. The first American pizzeria opened in Manhattan in 1905, and enjoyed a boom in popularity shortly after World War II. The food was not uncommon in Chicago during the '40s, but pie from The Pizzeria (which changed its name to Pizzeria Uno in 1955) stood out due to its unique construction, and sheer weight. 

Sewell and Riccardo may be the founders of the restaurant that popularized deep dish, but they probably didn't create the new style of pizza themselves. Neither of them had any cooking experience, so it’s unlikely they were able to concoct an entirely new recipe. 

So who’s the mystery chef behind the Chicago favorite? One strong possibility is Adolpho "Rudy" Malnati, Sr. The Italian-born employee worked as a bartender for Pizzeria Uno. His son, Rudy Malnati Jr. has a 1956 news clipping that refers to his father as the one who established Pizzeria Uno. In 1991, the younger Malnati opened his own pizzeria—the famous Pizano’s. 

Other Pizzeria Uno employees are also suspected of having created the new style; many moved on to make deep dish pizza at other locations. Alice May Redmond, a former cook for Uno’s, eventually went to bake pies at Gino’s East. 

Unfortunately, the world may never know what individual created the Chicago treat. "It's an enigma, wrapped in a pie crust. Every day, it feels a little more lost to history," Jeff Ruby, co-author of Everybody Loves Pizza told the Chicago Tribune.

Big Questions
Where Should You Place the Apostrophe in President's Day?

Happy Presidents’ Day! Or is it President’s Day? Or Presidents Day? What you call the national holiday depends on where you are, who you’re honoring, and how you think we’re celebrating.

Saying "President’s Day" infers that the day belongs to a singular president, such as George Washington or Abraham Lincoln, whose birthdays are the basis for the holiday. On the other hand, referring to it as "Presidents’ Day" means that the day belongs to all of the presidents—that it’s their day collectively. Finally, calling the day "Presidents Day"—plural with no apostrophe—would indicate that we’re honoring all POTUSes past and present (yes, even Andrew Johnson), but that no one president actually owns the day.

You would think that in the nearly 140 years since "Washington’s Birthday" was declared a holiday in 1879, someone would have officially declared a way to spell the day. But in fact, even the White House itself hasn’t chosen a single variation for its style guide. They spelled it “President’s Day” here and “Presidents’ Day” here.

Maybe that indecision comes from the fact that Presidents Day isn’t even a federal holiday. The federal holiday is technically still called “Washington’s Birthday,” and states can choose to call it whatever they want. Some states, like Iowa, don’t officially acknowledge the day at all. And the location of the punctuation mark is a moot point when individual states choose to call it something else entirely, like “George Washington’s Birthday and Daisy Gatson Bates Day” in Arkansas, or “Birthdays of George Washington/Thomas Jefferson” in Alabama. (Alabama loves to split birthday celebrations, by the way; the third Monday in January celebrates both Martin Luther King, Jr., and Robert E. Lee.)

You can look to official grammar sources to declare the right way, but even they don’t agree. The AP Stylebook prefers “Presidents Day,” while Chicago Style uses “Presidents’ Day.”

The bottom line: There’s no rhyme or reason to any of it. Go with what feels right. And even then, if you’re in one of those states that has chosen to spell it “President’s Day”—Washington, for example—and you use one of the grammar book stylings instead, you’re still technically wrong.

Big Questions
How Do You Steer a Bobsled?

Now that the Olympics are well underway, you might have developed a few questions about the games' equipment. For example: How does one steer a bobsled? Let's take a crack at answering this pressing query.

How do you steer a bobsled?

Bobsled teams careen down an icy, curving track at up to 90 miles per hour, so steering is no small concern. Drivers steer their sleds just like you steered your childhood sleds—by manipulating a pair of ropes connected to the sled's steel runners. The driver also gets help from the rest of the crew members, who shift their weight to aid with the steering.

Why do speed skaters wear glasses?

Speed skaters can fly around the ice at upwards of 40 mph, so those sunglasses-type specs they wear aren't merely ornamental. At such high speeds, it's not very pleasant to have wind blowing in your eyes; it's particularly nightmarish if the breeze is drying out your contact lenses. On top of that, there's all sorts of ice and debris flying around on a speed skating track that could send you on a fast trip to the ophthalmologist.

Some skaters also say the glasses help them see the track. American skater Ryan Bedford recently told the Saginaw News that his tinted shades help him focus on the track and filter out distracting lights and camera flashes from the crowd.

What kind of heat are the biathletes packing?

As you might guess, there are fairly strict rules governing what sort of rifles biathletes carry on the course. They are equipped with guns chambered for .22 LR ammunition. The gun must weigh at least 3.5 kilograms without its magazines and ammunition, and the rifle has to have a bolt action or a straight-pull bolt rather than firing automatically or semi-automatically.

Is a curling stone really made of stone?

You bet it is, and it's not just any old stone, either. Curling enthusiasts swear by a very specific type of granite called ailsite that is only found on the Scottish island of Ailsa Craig. Ailsite supposedly absorbs less water than other types of stone, so they last longer than their competitors.

Ailsa Craig is now a wildlife sanctuary, so no new ailsite has been quarried since 2002. As a result, curling stones are incredibly expensive. Kays of Scotland, which has made the stones for every Olympics in which curling has been an official event, gets prices upwards of $1,500 per stone.

What about the brooms?

The earliest curling brooms were actual brooms made of wood with straw heads. Modern brooms, though, are a bit more technologically advanced. The handles are usually made of carbon fiber, and the heads can be made of synthetic materials or natural hair from horses or hogs. Synthetic materials tend to be more common now because they pull all of the debris off of the ice and don't drop the occasional stray bristle like a natural hair broom might.

What are the ski jumpers wearing?

It may look like a ski jumper can pull on any old form-fitting bodysuit and hit the mountain, but things are a bit more complicated than that. Their suits have to be made of a spongy material and can't be thicker than five millimeters. Additionally, the suits must allow a certain amount of air to pass through them; jumpers wearing suits without sufficient air permeability are disqualified. (This rule keeps jumpers from wearing suits that could unfairly act as airfoils.) These rules are seriously enforced, too; Norwegian skier Sigurd Petterson found himself DQed at the 2006 Torino Games due to improper air permeability.

Those aren't the only concerns, though. In 2010, judges disqualified Italian jumper Roberto Dellasega because his suit was too baggy.

What's up with the short track speed skaters' gloves?

If you watch a bit of short track speed skating, the need for gloves quickly becomes apparent. When the skaters go to make passes or careen around a turn, they need the gloves to keep from cutting their hands due to incidental contact with other skaters' blades.

There's more to the gloves than just safety, though. Since the skaters' hands often touch the ice during turns, they need hard fingertip coverings that won't add friction and slow them down. The tips can be made of any material as long as it's hard and smooth, but you've got to give American skater Apolo Ohno some style points for the gold-tipped left glove he broke out in 2010.
