You probably think fear only affects everyday people, but some of history’s biggest names had anxieties that shaped their choices and personalities. Phobias aren’t just quirks; they’re intense reactions your brain treats as real threats, even when danger is minimal.
Diaries, letters, and biographies reveal that inventors, leaders, and artists lived with fears most would find surprising. Courage often coexists with vulnerability, showing how fear influenced lives we think we already understand.
These stories remind you that even greatness doesn’t erase human fragility. They show how personal struggles can coexist with public triumphs.
1. Howard Hughes’s Fear of Germs (Mysophobia)
Howard Hughes, the pilot and industrialist, was famous for daring aviation feats, yet he lived with an extreme fear of germs that grew worse over time. His avoidance wasn’t casual dislike; it was a pattern of behavior that controlled his environment.
Hughes washed until his skin was sore, sealed doors and surfaces, and limited human contact. He even had staff handle items with tissues and refused handshakes.
What’s startling is how someone who took the skies could feel unsafe in simple human encounters. This fear shaped his later life, pulling him away from public view and into self‑imposed isolation.
2. Nikola Tesla’s Fear of Germs and Pearls
Nikola Tesla was brilliant with electricity, but his personal habits reveal an anxiety you wouldn’t expect from such a rational mind. Tesla’s discomfort with germs went beyond neatness; he avoided handshakes, counted steps, and stuck to rituals that made the world feel predictable.
What takes it a step further is his reaction to pearls. Seeing someone wear them made him uneasy, and he would sometimes refuse to speak with pearl wearers.
Tesla’s routines weren’t mere preferences; they were coping strategies for the intense discomfort his brain associated with unpredictability and contamination. His fears shaped his habits.
3. Hans Christian Andersen’s Fear of Being Buried Alive (Taphophobia)
Hans Christian Andersen, the storyteller behind unforgettable fairy tales, lived with a profound fear that seems almost gothic today: the terror of being buried while still alive. This fear, known as taphophobia, was common in his era before modern medical certainty, but Andersen took it further.
He carried written instructions asking attendants to verify that he was truly dead before burial. The fear was enough that he told doctors and caretakers to check vital signs carefully.
It’s one thing to write dark fairy tales, but Andersen’s personal dread shows how even creative minds carry deep, human fears rooted in the fragility of life.
4. Franklin D. Roosevelt’s Fear of the Number 13
Franklin D. Roosevelt, the U.S. president who led the nation through crisis, publicly embraced courage, yet privately had a strong aversion to the number 13. His discomfort wasn’t casual superstition; he avoided travel or events on Friday the 13th.
Roosevelt sometimes rearranged or paused plans to dodge the number, showing how even command on the world stage can coexist with personal unease. His careful avoidance reveals how deeply personal fears can shape daily decisions. It also shows that even the most powerful figures live with small but persistent anxieties. These fears remind you- everyone has vulnerabilities, no matter their status.
5. Salvador Dalí’s Fear of Insects
Surrealist artist Salvador Dalí explored strange imagery on canvas, but his real-life fear of insects was more than artistic flair. Dalí didn’t just dislike bugs; he reacted with genuine panic when he believed insects were on him.
In one intense moment, he tried to remove what he thought was a tick with a razor blade, a risky choice that showed how visceral the fear felt to him. Insects are small, but for Dalí, they triggered a response that tipped into anxiety and discomfort. His vivid art may have amplified odd themes, but his nervous system had its own, very human alarm system.
This fear shaped how he moved through everyday life.
6. Aretha Franklin’s Fear of Flying
Aretha Franklin’s voice carried around the world, but for decades she avoided flying after a turbulent experience reshaped her comfort with air travel. The fear wasn’t a mild dislike; it dictated how she toured and traveled.
Instead of jets, she chose buses, lengthening journeys and reshaping schedules to suit how she felt safe. You might assume that someone with global fame would confront fear head‑on, yet Franklin’s solution was to adapt and keep performing in a way that felt manageable.
Her fear didn’t stop her career; it just changed how she lived it. It also shows how personal anxieties can shape even the busiest, most public lives.
7. Isaac Asimov’s Lifelong Flight Avoidance
Isaac Asimov wrote hundreds of books and captivated readers with visions of the future, but he rarely flew. His avoidance of airplanes wasn’t a casual preference; it was a consistent pattern that influenced how he traveled between cities and countries. Instead of air travel, he took trains and ships, sometimes adding days to trips because flight anxiety simply didn’t fit his comfort zone.
For someone whose imagination soared through space and time on the page, real‑world travel triggered a fear response that shaped choices throughout his adult life. This cautious approach shows how even brilliant minds manage deep personal anxieties.
8. Julius Caesar’s Fear of Thunder
Even Julius Caesar, whose military career and political genius helped reshape the ancient world, had moments of unease you wouldn’t expect from a conquering general.
Ancient sources suggest he responded to thunder and lightning with visible fear, seeking shelter and protection during storms. This intense avoidance of thunder, known as brontophobia, appeared not as a joke but as a genuine reaction to the power and unpredictability of nature.
That one of Rome’s most formidable figures could be unnerved by the weather shows how deeply fear is wired into the human brain, towering reputation or not.
9. Emily Dickinson’s Social and Open Space Anxiety
Poet Emily Dickinson created powerful verse from her home, but letters and accounts hint at a nervous system finely tuned to overwhelm in open or crowded spaces. Dickinson preferred thresholds and quiet gardens over parlors full of visitors, choosing solitude because it calmed her rather than isolated her.
What looks like reclusiveness was, in part, a real discomfort with social exposure. Writers and thinkers often lean into solitude, but for Dickinson, it was more than a preference; it was a way to manage the sharp anxiety that accompanied too many stimuli at once, letting her mind focus where it felt safe.
