Famous Coffee Lovers: Napoleon, Bach & Mathematicians

When you think of the great minds of history — military geniuses, composers, mathematicians — you might not immediately picture them hunched over a cup of coffee. But the truth is, some of the most influential figures in art, science, and war were as passionate about their daily brew as they were about their life’s work. What did they drink? Where did they go? And what did coffee really mean to them? Here are the real stories.

At least three iconic figures — French Emperor Napoleon, German composer Bach, and Polish mathematicians Banach and Ulam — had deep, documented connections to coffee. Napoleon reportedly pawned his military cap for a coffee tab, Bach composed a full coffee-themed comic opera, and Banach and Ulam co-created the famed ‘Scottish Book’ of unsolved math problems over years of café sessions.

Napoleon: The Emperor Who Pawned His Hat for Coffee

Before becoming Emperor, a young, stocky Napoleon Bonaparte was a frequent presence at Paris’s Regency Café (Café de la Régence), a hub for chess and political debate. On one occasion, he finished his coffee but couldn’t pay — and left his military cap with the waiter as collateral. Though brief, the story underlines his love for both caffeine and chess. He played often at the café, though with limited skill, once complaining that ‘chess is too difficult to be merely a game, yet not precise enough to be a science.’ To this day, Regency Café displays the original copper-rimmed chess table he used.

Bach: Coffee, Comedy, and Community

Johann Sebastian Bach, born in 1685 in a German town, was a prolific composer — and an avid coffee drinker. He didn’t just enjoy coffee alone; he actively encouraged friends and relatives to join him. During the 18th century, coffeehouses across Germany served as vital social spaces and even hosted live music. In 1732, likely fueled by his regular coffee habit, Bach wrote the Coffee Cantata (BWV 211), a comic opera about a father’s struggle with his coffee-addicted daughter. It premiered at a Leipzig coffeehouse to great acclaim. Later, when students couldn’t afford tuition, Bach used his position as a church musician to organize café performances — a clever way to help them earn money while enjoying music and coffee together.

Banach & Ulam: Coffee, Calculations, and the Scottish Book

Polish mathematicians Stefan Banach and Stanisław Ulam were central figures in the Lwów School of Mathematics. They spent hours — sometimes entire days — in cafés, furiously working through complex equations. So much so, that the café owners grew concerned about their wooden tables being ruined by chalk and pencil marks. To protect their furniture, one owner started providing a dedicated notebook alongside coffee. This evolved into the legendary ‘Scottish Book,’ a record of 193 challenging mathematical problems compiled between 1935 and 1941. Many remain unsolved. The term ‘Scottish Café mathematics’ now refers to the informal yet highly productive problem-solving culture that flourished in that café setting. Ulam later played a key role in the U.S. atomic bomb project, but he often looked back fondly on those coffee-fueled mathematical marathons.

Why These Stories Matter

These accounts show how coffee wasn’t just a drink — it was a catalyst for creativity, debate, and collaboration. From imperial strategy to comic opera and groundbreaking mathematics, coffee helped fuel some of history’s most memorable achievements. The settings — whether a Parisian chess café, a Leipzig music house, or a Polish academic coffee spot — became second offices for genius.

Frequently Asked Questions

Did Napoleon really pawn his military hat for coffee?

Yes. Before he became Emperor, a young Napoleon Bonaparte was at Paris’s Regency Café and, unable to pay his coffee bill, left his military cap with the waiter as collateral. This small incident is one of the few verifiable anecdotes confirming his regular presence in the café and his love for coffee.

What coffee-related work did Bach create?

In 1732, Bach composed the Coffee Cantata (BWV 211), a comic opera about a father dealing with his coffee-obsessed daughter. Likely inspired by his own frequent café visits and love of coffee, the piece premiered successfully at a Leipzig coffeehouse and remains one of his most accessible and entertaining works.

What is the Scottish Book?

The Scottish Book is a legendary notebook of 193 unsolved mathematical problems, created between 1935 and 1941 by Polish mathematicians Stefan Banach and Stanisław Ulam and their peers. It originated when a café owner provided a notebook to protect his tables from being covered in calculations. Many problems remain unsolved to this day.

Where did Banach and Ulam develop their famous mathematical theories?

Banach and Ulam developed many of their ideas at a café in Lwów (now Lviv), working long hours over coffee. Their routine of solving problems together in a café led to the creation of the ‘Scottish Book’ — a key historical document in 20th-century mathematics.

Did these historical figures drink coffee the way we do today?

While we don’t know their exact brew methods, they drank coffee as it was prepared in their eras — likely roasted dark and brewed simply, perhaps as filter or boiled coffee. Their devotion to the drink, however, mirrors that of many dedicated coffee drinkers today.

Are the cafés they frequented still around?

Yes. The Regency Café (Café de la Régence) in Paris still exists and displays the copper-rimmed chess table used by Napoleon. While the original Lwów café is gone, the legacy of the Scottish Book lives on in mathematical history.
