The horse diaper

Image: Lucia Macedo

Designed to catch manure in crowded cities—a problem once so severe that it shaped public infrastructure as well as the entrances to houses—the horse diaper was an invention meant to be strapped beneath working horses pulling carts and carriages.

The idea was to reduce disease and street filth during the horse-powered urban era. While the device saw limited use before automobiles rapidly replaced horses, similar designs are still occasionally used in modern veterinary practice.

The baby cage

Image: Taylor Flowe

Built as wire cages attached to apartment windows, so-called "baby cages" allowed infants to get fresh air when outdoor space was unavailable. Some models were guaranteed to safely hold over 30 pounds.

While alarming today and ultimately abandoned due to obvious safety concerns, the designs likely inspired some of the baby-proofing nets used today.

The pneumatic subway

Image: Eddi Aguirre

In the late 1860s, American entrepreneur and inventor Alfred Ely Beach set out to prove the feasibility of a human-sized pneumatic subway system beneath New York City, capable of moving both people and cargo using nothing more than air pressure.

The prototype was set up as a public attraction and carried passengers along a tunnel just over 300 feet long, from a station to a dead end. Despite its initial success, bureaucratic obstacles and high costs halted expansion, leaving it as a functional but largely forgotten underground experiment.

The mechanical horse

Image: Gabriel Tovar

Created for exercise and riding practice, the mechanical horse used a system of gears, cranks, and pedals to simulate walking and trotting motions while the rider sat in a saddle-like seat. It was marketed to urban riders and cavalry trainees who lacked access to stables or live horses.

Though bulky and impractical for widespread use, the device anticipated modern fitness machines by replicating real-world movements for conditioning and skill retention, rather than simple repetitive exercise.

The first metal detector

Image: Fer Troulik

After a failed assassination attempt on President James Garfield, Alexander Graham Bell hastily built an early metal detector in an effort to locate the bullet lodged in his body. The device functioned as intended, but it was unable to find the bullet because metal bed springs interfered with the signal.

Despite this setback, Bell’s early design proved the concept and directly influenced the development of modern metal detectors.

The pet-powered butter churn

Image: Matt Bero

In an inventive twist on animal-powered machinery, some 19th-century American farmers rigged small treadwheels for dogs, cats, or even goats to generate kinetic energy for churning butter. The animal ran inside the wheel, turning a rope or pulley connected to the churn.

While technically functional, the system was limited by the animal's willingness to cooperate and the small amount of power it generated.

The umbrella hat

Image: Claudio Schwarz

Robert W. Patten, often called the "Umbrella Man," patented one of the first commercially successful hands-free umbrella hats. It strapped a small umbrella directly to the wearer’s head, providing both sun and rain protection while keeping the hands free for work or walking.

His original design even included a mosquito net attached to the canopy. Patten didn’t enjoy much commercial success but became somewhat of an eccentric and comical popular figure, partly due to a series of comics that were inspired by his unusual invention.

The one-wheel motorcycle

Image: CJ Toscano

In 1971, American inventor Kerry McLean built and refined a monowheel—a one‑wheeled motorized vehicle in which the rider and engine sit inside the wheel’s circumference.

Since then, various attempts have been made to build on his original design, but it remains a niche vehicle used primarily for entertainment rather than practicality, as riders must be highly skilled simply to turn or even stay upright.

The first talking doll

Image: Holly Ward

In 1890, Thomas Edison embedded miniature versions of one of his most popular inventions —the phonograph—inside dolls so they could recite nursery rhymes.

While the idea was innovative, the technology was not yet there. The recordings were fragile, distorted, and often failed to work properly. The dolls were pulled from the market within weeks due to customer complaints, making it one of Edison’s rare commercial failures.

The glass harmonica

Image: Francesco Bovolin

Faithful to his eccentricity and inventive spirit, Benjamin Franklin redesigned the existing glass harp into a rotating spindle of glass bowls, played by touching the spinning rims with wet fingers, which he called the "glass harmonica."

The instrument produced eerie, sustained tones unlike anything else of its era. However, its fragile nature made it somewhat impractical, and the rotating mechanism posed a potential danger to the player if anything went wrong.

Ella Fitzgerald and Marilyn Monroe

Strange as it may sound, Ella Fitzgerald and Marilyn Monroe developed a beautiful friendship in the 1950s. Hollywood's favorite blonde was a big fan of Fitzgerald's music and went to see her perform in Los Angeles in 1954. When they met in person they became inseparable.

Monroe helped her land a gig at the famous Mocambo nightclub in Los Angeles, which had previously turned Fitzgerald down. These performances were a turning point in the career of the Queen of Jazz. Marilyn used to say that Ella was her favorite person and that she loved her as a person and as a singer. They remained friends until Monroe's death at the age of 36.

Thomas Jefferson and John Adams

John Adams and Thomas Jefferson are perhaps America's most famous pair of "frenemies". Their historic relationship began in 1775. Despite their very different political views, the two Founding Fathers maintained an on-and-off relationship for five decades, tinged by a mixture of mutual respect and contempt.

Their relationship began to crack when George Washington decided not to run for a third term, and Adams and Jefferson had to compete for the presidency. They stopped speaking to each other for 12 years, but finally, in 1812, they resumed contact. Perhaps as proof of their troubled but strong friendship, John Adams and Thomas Jefferson died just a few hours apart on July 4, 1826, the 50th anniversary of the adoption of the Declaration of Independence.

Groucho Marx and T.S. Eliot

Image: Flybynight

One was a comedian of the absurd, the other a melancholic poet and Nobel laureate. Believe it or not, Groucho Marx and T.S. Eliot were friends and admired each other. In 1961, Eliot wrote to Marx, telling him he was a fan and asking for an autographed photo. Marx agreed to the request and asked the same of Eliot. For the next three years, the two became pen pals, exchanging many letters.

According to Groucho Marx, they shared three things: an affection for good cigars, a love of cats, and a weakness for puns. However, when they finally met in person in 1964 they realized that they didn’t have that much in common after all and their relationship started to fade.

Ulysses S. Grant and James Longstreet

Ulysses S. Grant was the commander of the Union Army during the Civil War. James Longstreet, on the other hand, fought for the Confederate Army and became one of General Robert E. Lee's most trusted officers. That should make them enemies, right? Well, not exactly.

Grant and Longstreet became friends as young officers in the US Army and served together in the Mexican-American War. Years later they went their separate ways but were reunited after the Confederate surrender at Appomattox Court House. In fact, it was Longstreet who convinced General Lee to surrender, knowing that Grant would offer him generous terms. As soon as Grant saw Longstreet, he shook his hand warmly and asked him to play a game of cards for old time's sake.

Susan B. Anthony and Elizabeth Cady Stanton

Susan B. Anthony is known for having been a tireless activist who dedicated most of her 86 years to achieving women's suffrage. In 1851, Anthony met suffragist Elizabeth Cady Stanton, with whom she developed a lifelong friendship. Together they launched a national women's suffrage movement, published a newspaper called The Revolution , and gave many lectures.

Stanton died in 1902 and Anthony in 1906. It was not until 1920 that women were allowed to vote legally for the first time in U.S. federal elections, yet the legacy of these two friends was certainly invaluable.

Mark Twain and Nikola Tesla

Can a literary genius and a giant of science become good friends? In the case of Mark Twain and Nikola Tesla, the answer is definitely yes. Although the professions of writer and inventor seem very different, they actually have something very strong in common: creativity.

Tesla, who had been bedridden for nine months because of cholera, found in Twain's work a refuge that made him completely forget his state of despair. Meanwhile, Twain was fascinated by technological innovations and, in particular, by electricity. When the two men finally met in the 1890s, they became close friends. Over the years they maintained an assiduous correspondence and supported each other both professionally and personally.

Bill Gates and Warren Buffett

Bill Gates and Warren Buffett, two of the richest men in the United States, have been friends for more than 30 years. They met in 1991 at a Fourth of July celebration, and although they thought they had nothing in common, they spent 11 hours discussing business and philanthropy.

Bill and Warren played ping-pong together, traveled the world for business and pleasure, and shared several initiatives to encourage billionaires to invest their money in social and charitable endeavors. The creator of Microsoft also claims that Warren Buffett's advice and business vision were indispensable for the growth of his company.

Mary Todd Lincoln and Elizabeth Keckley

In the 1860s, Elizabeth Keckley, a former slave who had managed to buy her freedom and start a sewing business, landed an important position in the White House as Mrs. Mary Todd Lincoln's personal dressmaker. Despite their different upbringings, the two women developed a close relationship. In fact, the first lady came to describe her as her best friend.

Over the years Keckley became a confidant of Mrs. Lincoln; the two women traveled and worked together to raise money for the war effort. Unfortunately, their friendship ended when Keckley published her memoirs in 1868. Keckley had wanted the book to celebrate Mrs. Lincoln's legacy, but the First Lady felt betrayed as it revealed some private conversations.

Dwight D. Eisenhower and Bob Hope

Throughout his long career, comedian Bob Hope was a frequent White House visitor who had the honor of entertaining 11 different commanders-in-chief. In fact, he considered them the best possible audience. But of all the presidents who laughed at his jokes, Dwight D. Eisenhower was the one with whom he formed the most enduring relationship.

They met in Algeria in 1943 when Eisenhower was a General for the U.S. Army and Hope was performing at a United Service Organization show. They immediately hit it off. Even when Ike became president 10 years later their friendship continued. They often exchanged letters and played golf together.

Ben Affleck and Matt Damon

Matt Damon and Ben Affleck met in the 1980s in Cambridge, Massachusetts when they were still young children. They bonded over their passion for basketball and acting, and have been friends ever since. In fact, while in high school, they often traveled together to audition.

Damon and Affleck's partnership is arguably one of the most successful in Hollywood. They not only acted in movies together several times, but they also co-wrote the screenplay for Good Will Hunting , which earned them an Academy Award for Best Original Screenplay in 1997.

11

Truman Capote and Barbara "Babe" Paley

Another controversial friendship was that of author Truman Capote and New York socialite Barbara "Babe" Paley. This odd couple met in the late 1960s after Capote published In Cold Blood and became something of a celebrity. They quickly became close friends and confidants.

However, when in 1975 Capote published a preview of his forthcoming book Answered Prayers in Esquire magazine airing some of his friend’s secrets, their relationship was forever ruined. Although the writer admired Babe and considered her perfect, he could not resist the temptation to betray her.

John F. Kennedy and Frank Sinatra

Image: FotoshopTofs

No one knows exactly when and how they met, but it is not surprising that US President John F. Kennedy and music legend Frank Sinatra were friends. In addition to their mutual admiration, their relationship was beneficial to both. Sinatra gained access to the halls of power, while Kennedy relied on The Voice's charm and popularity to win votes in the 1960 presidential election.

When Kennedy won, the president-elect publicly thanked Sinatra for his campaign efforts. Unfortunately, the friendship fell apart after JFK entered the White House. According to lore, First Lady Jackie Kennedy didn't like the singer. And, let's be honest, Sinatra's alleged connections to organized crime weren't a good look for a head of state anyway.
