Harriet Tubman secretly worked as a Union spy

Most Americans know Harriet Tubman for her leadership of the Underground Railroad, but during the Civil War, she also became a Union scout and spy in South Carolina. Working with Colonel James Montgomery, Tubman gathered intelligence from enslaved people living behind Confederate lines near the Combahee River .

In June 1863, Tubman helped lead the Combahee River Raid, guiding Union gunboats through Confederate waters filled with hidden mines. The operation freed more than 700 enslaved people and made Tubman the first woman known to lead a major U.S. military mission.

Julia Child worked for the U.S. intelligence agency

Before becoming television’s most famous chef, Julia Child joined the Office of Strategic Services, or OSS, in 1942 during World War II. The OSS later evolved into the CIA. Too tall to enlist in the Women’s Army Corps, Child instead classified files and overseas communications in Asia.

One of her strangest assignments involved helping researchers develop shark repellent for Navy explosives and emergency rescue kits . The repellent used copper acetate and black dye to create an odor similar to a dead shark.

Benjamin Franklin conducted unofficial spy work in Europe

Benjamin Franklin was more than a scientist and Founding Father. During the American Revolution, he quietly acted as an intelligence organizer while serving as ambassador to France beginning in 1776 . Franklin cultivated secret alliances, intercepted information, and used coded correspondence to support the colonies’ fight against Britain.

Operating from Paris, Franklin built relationships with French officials and helped persuade France to support the American cause with money, troops, and naval power. Historians consider his diplomatic intelligence efforts essential to the American victory at Yorktown in 1781 and eventual independence.

Louisa May Alcott published thrillers under another name

Louisa May Alcott became a literary icon after publishing Little Women in 1868, but few readers knew that she had already written sensational thrillers under the pen name "A.M. Barnard." These stories featured revenge, hidden identities, forbidden romance, and dramatic crime plots that shocked Victorian audiences.

Alcott used a pseudonym because publishers often expected women writers to produce respectable domestic fiction. Many of her darker stories remained forgotten until scholars rediscovered them in the 1940s. Today, titles like Behind a Mask reveal a far more rebellious side of the beloved author.

Maya Angelou worked as San Francisco’s first black female cable car conductor

Long before becoming a celebrated poet and author, Maya Angelou made history in San Francisco during the 1940s. At only 16 years old, she applied repeatedly for a conductor job on the city’s cable cars after seeing an advertisement that excluded Black applicants .

Angelou refused to give up despite repeated rejection. She eventually became San Francisco’s first Black female cable car conductor in 1944. Years later, she described proudly wearing the blue uniform while working long shifts across the city before launching her writing and civil rights careers.

Dr. Seuss created classified wartime propaganda films

Before writing Green Eggs and Ham and The Cat in the Hat , Theodor Geisel, better known as Dr. Seuss, worked on wartime propaganda during World War II. Between 1943 and 1945, he joined director Frank Capra’s Signal Corps unit to produce military training films for American soldiers .

Geisel also drew political cartoons supporting the Allied war effort and criticizing fascism. Some of his films were classified during the war because they contained military training material. His animated work helped explain battlefield strategy and morale issues to thousands of U.S. troops overseas.

7

Babe Ruth once played an entire game with a fever over 102 degrees

In 1925, Babe Ruth became seriously ill during spring training and collapsed while traveling by train . Newspapers nicknamed the incident "the bellyache heard around the world." Reports from the time described Ruth suffering from a fever above 102 degrees while still insisting on returning to baseball activities.

Despite his condition, Ruth’s determination became part of baseball legend. The illness hurt his performance during the 1925 season, when the New York Yankees finished seventh in the American League. Even so, Ruth rebounded quickly and helped lead the Yankees to championships in later years.

Harry Houdini worked with police departments

Harry Houdini’s famous escape acts fascinated police departments across America and Europe in the early 1900s. Officers regularly challenged him to escape from handcuffs, prison wagons, and locked jail cells. Houdini often invited local police to inspect restraints before his performances began.

Beyond entertainment, Houdini also worked closely with law enforcement to expose fraudulent mediums and fake spiritualists during the 1920s . Using his knowledge of locks, hidden compartments, and deception, he publicly demonstrated how many supposed supernatural tricks were actually carefully staged illusions.

Frank Lloyd Wright hid a private apartment inside one of his buildings

Architect Frank Lloyd Wright secretly maintained a private apartment inside his famous Oak Park Studio near Chicago, Illinois. Built in the 1890s, the studio served as both his workplace and personal retreat while he designed many of his early Prairie-style homes across the Midwest.

The hidden living quarters allowed Wright to work late into the night and host select guests away from public attention. The building itself became one of the most important centers of American architecture, producing groundbreaking residential designs that influenced modern architecture around the world.

Muhammad Ali quietly funded humanitarian causes for years

Muhammad Ali’s boxing fame often overshadowed his enormous charitable work. For decades, Ali quietly donated money to hospitals, food programs, children’s charities, and international humanitarian efforts . Friends and family later revealed that many of his contributions were intentionally kept private.

In 1990, Ali traveled to Iraq during tensions leading up to the Gulf War and helped secure the release of 15 American hostages. He also supported global relief organizations and Parkinson’s disease research after his own diagnosis. In 2005, President George W. Bush awarded Ali the Presidential Medal of Freedom.

Bohemians

Bohemianism, an original subculture that ended up lending its name as an adjective often used to describe other subcultures, is a social and cultural movement that embraces a way of life away from society's conventional norms and expectations . The term comes from the French bohème , and it was used to describe mid-19th-century non-traditional lifestyles, especially those of artists, writers, journalists, musicians, and actors.

Today, the term is used to describe anyone who shows disdain for money, dresses in hippie fashion (more on this later), and appreciates everything art-related.

2

Greasers

Think John Travolta in _Grease_—yes, Grease . Think Biff Tannen in the 1950s segment of Back to the Future . Greasers emerged in the 1950s and early 1960s from predominantly working-class and lower-class teenagers and young adults in the United States and Canada.

An interest in cars, motorcycles, leather jackets, jeans, and rock music was the common theme among greasers. According to some sources, the subculture’s name was applied to its members partly because of their characteristic greased-back hair.

3

Beatniks

The first subculture on this list to adopt the adjective "bohemian," beatniks were a mid-20th-century social movement that embraced an anti-materialistic lifestyle, rejecting consumerism and expressing themselves through art, spirituality, drugs, and sexuality.

The term "beat" was first used by Jack Kerouac in 1948 to describe his group of friends and fellow writers, including Allen Ginsberg, William S. Burroughs, and Neal Cassady. Kerouac said that "beat" had multiple meanings, such as "beaten down," "beatific," "beat up," and "beat out." Beatniks are often stereotyped as wearing black clothing, and speaking in hip slang that incorporates words like "cool," "dig," "groovy," and "square."

Hippies

One of the most famous countercultures of all time, hippies are deeply associated with the 1960s. The term "hippie" originally came from "hipster" (more on this later) and was used to describe the aforementioned Beatniks, who were "hip" to all things sophisticated and fashionable. In fact, early hippies adopted much of the language and values of the Beat Generation.

The festivals of Human Be-In (1967), Monterey (1967), and Woodstock (1969) popularized hippie culture, with its fashion and values influencing culture, popular music, television, film, literature, and the arts. Since the 1960s, mainstream society has assimilated many aspects of Hippie culture.

Mods

The Mods were a group of stylish, London-based young men and women in the late 1950s, named for their preference for modern jazz. This subculture was known for its distinctive fashion, including tailor-made suits, as well as its love for music and scooters.

By the mid-1960s, their musical tastes had shifted toward rock and blues, with bands like The Who and Small Faces gaining popularity among Mods. Mod fashion was a defining element of the "Swinging London" era, and during this time, the subculture spread to other countries, becoming emblematic of the larger youth culture of the period.

6

Punks

Another popular subculture, thanks in no small part to its striking visual component, is the punk movement, which encompasses music, fashion, ideologies, dance, film, and visual arts, among other forms of expression. Its strong anti-establishment views, stances on individual freedom, and DIY ethic make punks easy to identify.

Punk fashion includes T-shirts, leather jackets, boots, distinctive hairstyles such as brightly colored hair and spiked mohawks, as well as cosmetics, tattoos, jewelry, and even body modification.

7

Yuppies

Anyone who has seen the movies Wall Street (the one with Charlie Sheen and Michael Douglas) or American Psycho knows what a yuppie is. The term stands for "young urban professional" and was coined in the early 1980s as a way to describe young professionals living in a city.

Those labeled as yuppies generally dislike the association, because this characterization often suggests a very materialistic approach to life in general and a cutthroat attitude towards the workplace environment.

8

Skaters

An offshoot of the punk subculture, skater culture rose to prominence in the 1980s when a massive drought in California left numerous empty pools, which skaters used to practice their sport. The rise of magazines like Thrasher and stars like Tony Hawk helped the movement transition from an underground scene to a mainstream sport.

Its aesthetics centered around the preferred type of clothes for skateboarding: baggy and sturdy pants, sneakers, and oversized shirts. Its music was shared by the punk and hardcore movements.

9

Straight Edge

Going deeper down the rabbit hole, we encounter the Straight Edge subculture, an offshoot of both skater and hardcore punk cultures. Its followers reject the excesses of the punk scene by abstaining from alcohol, tobacco, and recreational drugs . Many also refrain from casual sex, follow a vegetarian or vegan diet, and avoid caffeine or prescription drugs. The name "Straight Edge" was inspired by the 1981 song "Straight Edge" by the hardcore punk band Minor Threat.

Overall, Straight Edge culture promotes a lifestyle of self-discipline, health, and community, and it continues to evolve while maintaining its roots in the hardcore punk scene.

10

Hipsters

The final entry on the list is dedicated to the most modern subculture in it: the hipsters. Mostly associated with perceived upper-middle-class white young adults who gentrify urban areas , hipster culture has been critiqued for lacking authenticity and focusing on consumption.

As mentioned earlier, members of this subculture typically do not self-identify as hipsters, as the term’s connotations are often unflattering. It is no coincidence that the term evokes the previously mentioned Beatniks, as that subculture can be seen as an early precursor to hipster culture.

The expedition was almost entirely unplanned

Theodore Roosevelt had originally envisioned a simple travel itinerary consisting of public lectures in Argentina and Brazil. However, when Brazilian officials offered him the chance to embark on a voyage of discovery alongside Brazilian explorer Colonel Cândido Rondon, the famously adventurous ex-president couldn’t resist. Without proper medical preparation or specialized gear, Roosevelt eagerly agreed to chart an unmapped 600-mile river.

2

The River of Doubt was unmapped and deadly

The river they sought to navigate, a tributary of the Aripuanã River in the tropical rainforest of the Amazon, was called Rio da Dúvida (River of Doubt) because no civilized mapmaker knew where it flowed or whether it was even navigable. Once the team launched their canoes onto the water in February 1914, they realized the river was a nightmare of endless rapids. Repeatedly smashed against rocks, the crew had to spend their days breaking into dense jungle canopy just to drag their heavy boats around impenetrable waterfalls.

3

Deadly insects and disease ravaged the crew

The Amazonian rainforest proved to be a relentless environment of venomous fauna and pests. Swarms of biting sandflies, bees, ticks, and mosquitoes tormented the men day and night. Malaria quickly spread through the crew, causing debilitating chills and burning fevers. Nearly every member, including Roosevelt and his son Kermit, suffered repeated bouts of severe tropical sickness that left them physically incapacitated in the damp heat.

4

Starvation was a constant threat

Due to the poor preparation, much of the expedition’s heavy canned food supply had to be abandoned along the trail to lighten the load. To make matters worse, as canoes overturned in violent rapids, crucial food provisions washed away downstream. Hunting in the dense rainforest wasn’t very fruitful, leaving the men on the verge. Consuming less than a fraction of the calories required for daily heavy labor, the crew was forced to forage for palm hearts, small fish, and whatever wildlife they could kill to avoid dying from starvation.

5

A murder led to a desertion

As exhaustion, heat, and hunger wore down morale, tempers within the crew flared. One irritated Brazilian porter named Julio was caught stealing food rations from his starving comrades. When another crew member, Paishon, confronted him over the theft, Julio drew a rifle and shot Paishon dead. Following the murder, Julio fled into the jungle. Knowing that hunting him down would kill more men, the expedition just left him behind.

6

Roosevelt nearly died from a wounded leg

Trying to prevent two canoes from smashing against boulders, Roosevelt hit his leg against a submerged rock, slicing open his shin. In the tropical humidity, the wound became infected, resulting in tropical fever and blood poisoning. Afflicted with fevers reaching 105ºF, Roosevelt became delirious. Realizing he was slowing down his son and the team, he fetched a lethal vial of morphine he carried for emergencies and prepared to end his own life, stating "I will stop here". Kermit firmly refused to abandon his father, forcing the crew to carry the bedridden former president along.

7

Encounters with mysterious indigenous tribes

Throughout their expedition, the crew was silently tracked by the Cinta Larga, an indigenous Amazonian tribe that remained completely uncontacted by the Western world. Though they rarely saw the warriors directly, they found freshly abandoned campsites and saw warning markers along the riverbanks. Years later, oral stories from the Cinta Larga revealed that tribal warriors had shadowed Roosevelt’s party for weeks, constantly considering killing the intruders with poisoned arrows before ultimately deciding to leave them alone.

8

Roosevelt lost over 50 pounds

When Theodore Roosevelt left New York in late 1913, he was a robust figure weighing over 220 pounds. By the time the expedition finally reached an outpost near the mouth of the river in late April 1914, the former president was a frail shadow of his former self. Roosevelt had lost over 50 pounds, could barely stand unassisted, and required help simply getting into and out of his hammock.

9

Discovery of new species

Despite the suffering, the expedition achieved remarkable scientific success. Accompanied by naturalists George Cherrie and Leo Miller from the American Museum of Natural History, the team collected and catalogued thousands of plant and animal specimens. They found over 2,500 birds, hundreds of mammals, and dozens of previously undescribed reptile and insect species, enriching the understanding of South American biodiversity.

10

Roosevelt’s Amazonian legacy

The expedition successfully put a major river on the map, which the Brazilian government officially renamed Rio Roosevelt (or Rio Teodoro ) in his honor. However, the physical toll permanently broke Roosevelt’s famous vigor. He suffered from recurring flare-ups of Malaria and inflammatory infections for the rest of his life. Historians generally agree that the severe damage sustained during his Amazonian ordeal directly contributed to his premature death just five years later in 1919 at age 60.
