First president to live in the White House

Image: Raymond M.E. Aguirre

In 1790, President George Washington signed an act of Congress declaring that the government would reside in a district "not exceeding ten miles square […] on the river Potomac." Today, we all know what stands at 1600 Pennsylvania Avenue NW in Washington, DC. That's right! We're talking about the White House, an enduring symbol of the US presidency.

But it hasn't always been that way. The construction of the White House began in 1792 and only had its first resident 8 years later. He was President John Adams, who moved into the Executive Mansion with his wife Abigail in 1800.

First president with telephone in Office

Nowadays, many of us can’t imagine getting anywhere without our cell phones. But in the 19th century, things were entirely different.

The landline telephone arrived at 1600 Pennsylvania Avenue in the late 1870s, during the presidency of Rutherford B. Hayes, shortly after Alexander Graham Bell had unveiled the communication device. It's said that President Hayes was interested in the technology and recognized its potential.

However, because the invention was so new, calls from the White House were rare. The first president to use the telephone frequently and regularly is considered to be William McKinley, who took office in 1897.

First president to serve two non-consecutive terms

Several men have had the honor of serving as president of the United States on more than one occasion, starting with none other than George Washington. Thomas Jefferson, James Madison, and others have served two consecutive terms.

But there was someone who, for the first time, served two non-consecutive terms as president: Grover Cleveland. That's right, Cleveland first took office in 1885 after defeating Republican candidate James G. Blaine in the election. In 1888, he lost the presidency to Benjamin Harrison. However, in 1892, Cleveland won again, assuming his second mandate in 1893.

First president to win the Nobel Peace Prize

Winning a Nobel Peace Prize is not something that happens every day, right? Fortunately, four US presidents have achieved this remarkable recognition.

The first was Theodore Roosevelt, who received the Nobel Peace Prize in 1906 for his role in negotiating the end of the Russo-Japanese War. The other three presidents who received the Nobel were Woodrow Wilson, Jimmy Carter (who was awarded the prize after leaving office), and Barack Obama.

First president born in the 20th century

Image: Florida Memory

The turn of the century is always a momentous and exciting event, and the first decades of the last century were quite... shall we say, "busy." The first president to serve during the 20th century was William McKinley, who was already in office at the turn of the century. But here’s a different question: who was the first future president born in the 20th century?

We're referring to none other than John F. Kennedy, who was born on May 29, 1917, in Brookline, Massachusetts. At the age of 29, he won a seat in the House of Representatives, and six years later, he secured a position in the Senate.

Finally, in 1961, JFK was inaugurated as the 35th president of the United States.

First president to light the National Christmas Tree

The lighting of the National Christmas Tree by the president of the country has become a cherished tradition that beautifully reflects the American Christmas spirit.

This tradition began on December 24, 1923, when President Calvin Coolidge became the first to light the National Christmas Tree located at the Ellipse near the White House. The imposing tree stood 48 feet tall and was decorated with over 2,500 electric lights. Beautiful!

Fortunately, the presidents who followed Coolidge have continued this delightful Christmas custom, keeping the tradition alive for generations to enjoy.

First president on TV

Image: Yle Archives

In the 1930s, it wasn't common to see the president's face on TV. In fact, before 1939, no president had ever appeared on television while in office.

The first American president on TV was Franklin D. Roosevelt, who made his television debut on April 30, 1939, at the New York World's Fair. Although this might not seem so revolutionary today, at the time, it marked a turning point in political communication and how leaders connected with citizens. His speech is remembered for addressing important issues, such as the future of the nation and the world.

First president on color TV

Image: Aleks Dorohovich

Yes, Franklin D. Roosevelt was the first US president to appear on TV, but Dwight D. Eisenhower was the first sitting US president who was lucky enough to appear on color television!

This detail, which seems trivial today, was a radical change at the time. When color TV arose, everything people watched on their living room screens began to better reflect the reality outside. Eisenhower made his color TV debut during the 1950s , delivering a speech as part of his re-election campaign—a moment that symbolized the merging of politics and modern technology.

First president to visit all 50 states

Image: David Lusvardi

We know that the United States of America is a big country. In fact, we're one of the largest countries in the world in terms of territory. For this reason, it can be a challenge to get to visit all 50 states that make up our nation in a short period of time. However, one president managed to accomplish this feat for the first time.

The president who achieved this milestone was Richard Nixon, the 37th president (1969-1974), when he visited Maine on October 22, 1972, marking the completion of his goal.

It’s worth noting, in fairness to all previous presidents, that Hawaii and Alaska didn’t become states until 1959.

First president on the internet

Image: Anthony Massaro

Although the origins of the Internet can be traced back to the 1960s, it wasn’t until the late 1980s that it became a widely popular and accessible phenomenon.

In line with global technological advances, the White House decided to incorporate the use of the Internet during the presidency of Bill Clinton, who officially became the first president to use the Internet for work purposes while in office.

But that wasn't all! Clinton also hosted an event that seemed unimaginable before —he organized a live chat from the White House. With that, Clinton was establishing the first direct communication between a US president and the public through the Internet.

As exotic as these treats might seem elsewhere, reindeer dogs are a normal thing in Anchorage, Alaska, as seen in the previous post, and this one, where the Polish-style dogs are the house’s specialty.

The menu even features names like Rudy-in-a-Parka and Chili-Rudy, as a nod to Santa Claus’ ride. But visitors can rest assured that the meats used don’t belong to the famous reindeer.

The Windy City makes a second entry at the last stop of our list with The Hot Dog Box, a father-daughter-managed joint venture. While classic Chicago-style hot dogs are on the menu, what makes this place a Chicago original is the craftier original creations that prove there's still room for creativity in the hot dog department.

The Bronzeville Bourbon Hot Dog is a menu star, comprised of a decadent steak dog covered with bourbon barbecue sauce, a fresh cabbage and carrot medley, and hickory-smoked bacon , all served in a pretzel bun.

This stunning subterranean retreat was built entirely by hand. Tucked under the sun-scorched landscape of Fresno, California, lie the Underground Gardens of Baldassare Forestiere .

Wind Cave National Park

Image: Francesco Ungaro

Wind Cave National Park, located in the Black Hills of South Dakota, is one of the world’s largest caves, but that’s not what it’s most famous for. One signature sight here is the boxwork formation , a rare lattice-like pattern formed by calcite deposits.

The cave system stretches for over 140 miles, though much of it remains unexplored. Popular tours take guests through captivating features like the "Ribbon Room" and the "Crystal Palace."

Why is Wind Cave called that? Mainly due to the "wind" phenomenon that occurs at its entrance. The cave's air pressure causes the entrance to draw in or expel air, depending on atmospheric conditions.
