Ada Lovelace: The First Computer Programmer

Ada Lovelace has been called the world's first computer programmer. What she did was write the world’s first machine algorithm for an early computing machine that existed only on paper. Of course, someone had to be the first, but Lovelace was a woman, and this was in the 1840s. Lovelace was a brilliant mathematician, thanks in part to opportunities that were denied most women of the time.

Ada Byron was a teenager when she met Cambridge mathematics professor Charles Babbage, who had invented the Difference Engine, a mechanical computer designed to produce mathematical tables automatically and error-free. Babbage never built the actual machine due to personal setbacks and financing difficulty. By 1834 he had moved on to design his Analytical Engine, the first general purpose computer, which used punch cards for input and output. This machine also lacked financing and was never built. (Babbage's Difference Engine was finally constructed in 1985–2002, and it worked.)

Babbage was impressed with the brilliant young woman, and they corresponded for years, discussing math and computing as he developed the Analytical Engine. In 1842, Babbage gave a lecture on the engine at the University of Turin. Luigi Menabrea, a mathematician (and future Italian prime minister), transcribed the lecture in French. Ada, now in her late 20s and known as Countess of Lovelace, was commissioned to translate the transcript into English. Lovelace added her own notes to the lecture, which ended up being three times as long as the actual transcript. It was published in 1843

Lovelace's notes made it clear that she understood the Analytical Engine as well as Babbage himself, and furthermore, she understood how to make it do the things computers do. She suggested the data input that would program the machine to calculate Bernoulli numbers, which is now considered the first computer program. But more than that, Lovelace was a visionary: she understood that numbers could be used to represent more than just quantities, and a machine that could manipulate numbers could be made to manipulate any data represented by numbers. She predicted that machines like the Analytical Engine could be used to compose music, produce graphics, and be useful to science. Of course, all that came true—in another 100 years. 

Babbage was so impressed with Lovelace's contributions, he dubbed her "The Enchantress of Numbers."

How did a young woman get the opportunity to show the world her talents in the 19th century? Mathematical intelligence was not the only thing Ada Lovelace had going for her. Her potential for intelligence probably came genetically, as she was the daughter of the poet Lord Byron and his first wife Anne Isabella Noel Byron. Both were privileged members of the aristocracy, and both were gifted and well educated. The marriage broke up shortly after Ada was born.

Lady Byron, who studied literature, science, philosophy, and, most unusual for a woman, mathematics, was determined that Ada not follow in her father's footsteps. Instead of art and literature, Ada was tutored in mathematics and science. Ada excelled in all her studies, and her interests were wide ranging. Ada became a baroness in 1835 when she married William King, 8th Baron King; the two had three children. In 1838, she became Countess of Lovelace when her husband was elevated to Earl of Lovelace. Her pedigree and peerage alone would have landed Lovelace in the history books, but her accomplishments in mathematics made her a pioneer of not only computing, but of women in science.

Lovelace died of cancer in 1852, when she was only 36. More than 150 years later, we remember her contributions to science and engineering in the celebration of Ada Lovelace Day on October 13. First celebrated in 2009 (in March), it is a day set aside to learn about women in science, technology, engineering, and mathematics.

15 Things You Might Not Know About Jules Verne

Jules Verne, widely regarded as one of the fathers of science fiction, wrote some of literature's most famous adventure novels, including seminal works like Journey to the Center of the Earth, Twenty Thousand Leagues Under the Sea, and Around the World in 80 Days. In addition to helping pioneer a new genre of writing, the French author also sailed the world, had a career as a stockbroker, fell in love with his cousin, and was shot by his nephew. Here are 15 facts you probably didn't know about him.

1. HE GREW UP SURROUNDED BY SHIPS.

On February 8, 1828, Pierre and Sophie Verne welcomed their first child, Jules Gabriel, at Sophie's mother's home in Nantes, a city in western France. Verne's birthplace had a profound impact on his writing. In the 19th century, Nantes was a busy port city that served as a major hub for French shipbuilders and traders, and Verne's family lived on Ile Feydeau, a small, man-made island in a tributary of the Loire River. Verne spent his childhood watching ships sail down the Loire and imagining what it would be like to climb aboard them [PDF]. He would later work these early memories of maritime life into his writing.

2. HE FELL IN LOVE WITH HIS COUSIN.

Verne began writing poetry at just 12 years old. As a teenager, he used poetry as an outlet for his burgeoning romantic feelings. Verne fell in love with his cousin, Caroline Tronson, who was a year and a half older than him. He wrote and dedicated poems to Tronson, gave her presents, and attended dances with her. Unfortunately, Tronson didn't reciprocate her younger cousin's feelings. In 1847, when Verne was 19 and Tronson was 20, she married a man two decades her senior. Verne was heartbroken.

3. HIS FATHER PRESSURED HIM TO BE A LAWYER.

While Verne had been passionate about writing since his early teens, his father strongly encouraged young Jules to follow in his footsteps and enter the legal profession. Soon after Tronson's marriage, Verne's father capitalized on his son's depression, convincing him to move to Paris to study law.

Verne graduated with a law degree in 1851. But he kept writing fiction during this period, and continued to clash with his father over his career path. In 1852, Verne's father arranged for him to practice law in Nantes, but Verne decided to pursue life as a writer instead.

4. HE LIVED IN PARIS DURING A TUMULTUOUS TIME.

Verne's time in Paris coincided with a period of intense political instability. The French Revolution of 1848 broke out soon after Verne moved to the city to study law. Though he didn't participate, he was strikingly close to the conflict and its turbulent aftermath, including the coup d'état that ended France's Second Republic. "On Thursday the fighting was intense; at the end of my street, houses were knocked down by cannon fire," he wrote to his mother during the fighting that followed the coup in December 1851. Verne managed to stay out of the political upheaval during those years, but his writing later explored themes of governmental strife. In his 1864 novella The Count of Chanteleine: A Tale of the French Revolution, Verne wrote about the struggles of ordinary and noble French people during the French Revolutionary Wars, while his novel The Flight to France recounted the wartime adventures of an army captain in 1792.

5. HE BECAME A STOCKBROKER TO PAY THE BILLS.

In May 1856, Verne was the best man at his best friend's wedding in Amiens, a city in northern France. During the wedding festivities, Verne lodged with the bride's family and met Honorine de Viane Morel, the bride's sister. He developed a crush on Morel, a 26-year-old widow with two kids, and in January 1857, with the permission of her family, the two married.

There was one big problem. Verne had been writing plays for Paris theaters, but being a playwright didn't pay the bills. Verne needed a respectable income to support Morel and her daughters. Morel's brother offered Verne a job at a brokerage, and he accepted, quitting his theater job to become a stockbroker at the Paris Bourse. Writing was never too far from Verne's mind, though. He woke up early each day to write and research for several hours before heading to his day job.

6. HIS ADVENTURE NOVELS WERE PART OF A SERIES …

Modern readers probably think of Verne's most famous books as distinct entities, but his adventure novels were actually part of a series. In the early 1860s, Verne met Pierre-Jules Hetzel, an established publisher and magazine editor who helped Verne publish his first novel, Five Weeks in a Balloon. This novel served as the beginning of Voyages Extraordinaires, a series of dozens of books written by Verne and published by Hetzel. Most of these novels—including famous titles like Twenty Thousand Leagues Under the Sea—appeared in installments in Hetzel's magazine before being published in book form.

7. … THAT PROVIDED HIM WITH A STEADY STREAM OF INCOME.

Starting in 1863, Verne agreed to write two volumes per year for Hetzel, a contract that provided him with a steady source of income for decades. Between 1863 and 1905, Verne published 54 novels about travel, adventure, history, science, and technology for the Voyages Extraordinaires series. He worked closely with Hetzel on characters, structure, and plot until the publisher's death in 1886. Verne's writing wasn't limited to this series, however; in total, he wrote 65 novels over the course of his life, though some would not be published until long after his death.

8. HE DREW INSPIRATION FROM HIS OWN SAILING ADVENTURES.

During the 1860s, Verne's career was taking off, and he was making good money. So in 1867, he bought a small yacht, which he named the Saint Michel, after his son, Michel. When he wasn't living in Amiens, he spent time sailing around Europe to the Channel Islands, along the English Coast, and across the Bay of Biscay. Besides enjoying the peace and quiet at sea, he also worked during these sailing trips, writing most of the manuscripts for Around the World in Eighty Days and Twenty Thousand Leagues Under The Sea on his yacht. As he earned more money, he replaced the Saint Michel with a larger boat that he called the Saint Michel II. A few years later, he bought a third vessel, the Saint Michel III, a steam yacht that he hired a crew of 10 to man on long voyages to Scotland and through the Mediterranean.

9. HE'S ONE OF THE MOST TRANSLATED AUTHORS IN THE WORLD …

Verne wrote in French, but his works have always had an international appeal. Since the 1850s, his writing has been translated into approximately 150 languages—making him the second most translated author ever. He has appeared in translation even more often than William Shakespeare. He is second only to Agatha Christie, who holds the world record.

10. … BUT NOT ALL OF THOSE TRANSLATIONS ARE ACCURATE.

Although Verne wrote primarily for adults, many English-language publishers considered his science fiction writing to be juvenile and marketed his books to children. Translators dumbed down his work, simplifying stories, cutting heavily researched passages, summarizing dialogue, and in some cases, nixing anything that might be construed as a critique of the British Empire. Many translations even contain outright errors, such as measurements converted incorrectly.

Some literary historians now bemoan the shoddy translations of many of Verne's works, arguing that almost all of these early English translations feature significant changes to both plot and tone. Even today, these poor translations make up much of Verne's available work in English. But anglophone readers hoping to read more authentic versions of his stories are in luck. Thanks to scholarly interest, there has been a recent surge in new Verne translations that aim to be more faithful to the original texts.

11. HE HAD MAJOR HEALTH PROBLEMS.

Starting in his twenties, Verne began experiencing sudden bouts of extreme stomach pain. He wrote about his agonizing stomach cramps in letters to family members, but he failed to get a proper diagnosis from doctors. To try to ease his pain, he experimented with different diets, including one in which he ate only eggs and dairy. Historians believe that Verne may have had colitis or a related digestion disorder.

Even more unsettling than the stomach pain, Verne suffered from five episodes of facial paralysis over the course of his life. During these painful episodes, one side of his face suddenly became immobile. After the first attack, doctors treated his facial nerve with electric stimulation, but he had another attack five years later, and several more after that. Recently, researchers have concluded that he had Bell's palsy, a temporary form of one-sided facial paralysis caused by damage to the facial nerve. Doctors have hypothesized that it was the result of ear infections or inflammation, but no one knows for sure why he experienced this.

Verne developed type-2 diabetes in his fifties, and his health declined significantly in the last decade of his life. He suffered from high blood pressure, chronic dizziness, tinnitus, and other maladies, and eventually went partially blind.

12. HIS MENTALLY ILL NEPHEW SHOT HIM IN THE LEG …

In March 1886, a traumatic incident left the 58-year-old Verne disabled for the rest of his life. Verne's nephew Gaston, who was then in his twenties and suffering from mental illness, suddenly became violent, to Verne's detriment. The writer was arriving home one day when, out of the blue, Gaston shot him twice with a pistol. Thankfully, Verne survived, but the second bullet that Gaston fired struck the author's left leg.

13. … LEAVING HIM WITH A PERMANENT LIMP.

After the incident, Gaston was sent to a mental asylum. He wasn't diagnosed with a specific disorder, but most historians believe he suffered from paranoia or schizophrenia.

Verne never fully recovered from the attack. The bullet damaged his left leg badly, and his diabetes complicated the healing process. A secondary infection left him with a noticeable limp that persisted until his death in 1905.

14. HIS WORK CONTRIBUTED TO THE RISE OF STEAMPUNK.

Verne's body of work heavily influenced steampunk, the science fiction subgenre that takes inspiration from 19th century industrial technology. Some of Verne's characters, as well as the fictional machines he wrote about, have appeared in prominent steampunk works. For example, the TV show The Secret Adventures of Jules Verne explored the idea that Verne actually experienced the fantastic things he wrote about, and Captain Nemo from Twenty Thousand Leagues Under the Sea appeared as a character in the comic book series The League of Extraordinary Gentlemen.

15. MANY OF HIS PREDICTIONS WERE SURPRISINGLY SPOT-ON.

Some of the technology Verne imagined in his fiction later became reality. One of the machines that Verne dreamed up, Nautilus—the electric submarine in Twenty Thousand Leagues Under the Sea—came to life years after he first wrote about it. The first installment of the serialized Twenty Thousand Leagues Under the Sea was published in 1869, and the first battery-powered submarines were launched in the 1880s. (Similar submarine designs are still in use today.)

In addition, Verne's Paris In The Twentieth Century contains several surprisingly accurate technological predictions. Written in 1863, the dystopian novel imagines a tech-obsessed Parisian society in 1960. Verne wrote about skyscrapers, elevators, cars with internal combustion engines, trains, electric city lights, and suburbs. He was massively ahead of his time. He even wrote about a group of mechanical calculators (as in, computers) that could communicate with one another over a network (like the Internet). Pretty impressive for a guy born in 1828.

But Verne's influence goes beyond science fiction, steampunk, or real-world technology. His writing has inspired countless authors in genres ranging from poetry to travel to adventure. As Ray Bradbury wrote, "We are all, in one way or another, the children of Jules Verne."

Stolpersteine: One Artist's International Memorial to the Holocaust

The most startling memorial to victims of the Holocaust may also be the easiest to miss. Embedded in the sidewalks of more than 20 countries, more than 60,000 Stolpersteine—German for “stumbling stones”—mark the spots where victims last resided before they were forced to leave their homes. The modest, nearly 4-by-4-inch brass blocks, each the size of a single cobblestone, are planted outside the doorways of row houses, bakeries, and coffee houses. Each tells a simple yet chilling story: A person lived here. This is what happened to them.

The project is the brainchild of the German artist Gunter Demnig, who first had the idea in the early 1990s as he studied the Nazis' deportation of Sinti and Roma people. His first installations were guerrilla artwork: According to Reuters, Demnig laid his first 41 blocks in Berlin without official approval. The city, however, soon endorsed the idea and granted him permission to install more. Today, Berlin has more than 5000.

The Stolpersteine are unique in their individuality. Too often, the millions of Holocaust victims are spoken of as a nameless mass. And while the powerful memorials and museums in places such as Berlin and Washington, D.C. are an antidote to that, the Stolpersteine are special—they are decentralized, integrated into everyday life. You can walk down a sidewalk, look down, and suddenly find yourself standing where a person's life changed. History becomes unavoidably present.

That's because, unlike gravestones, the stumbling stones mark an important date between a person’s birth and death: the day that person was forced to abandon his or her home. As a result, not every stumbling stone is dedicated to a person who was murdered. Some plaques commemorate people who fled Europe and survived. Others honor people who were deported but managed to escape. The plaques aim to memorialize the moment a person’s life was irrevocably changed—no matter how it ended.

The ordinariness of the surrounding landscape—a buzzing cafe, a quaint bookstore, a tree-lined street—only heightens that effect. As David Crew writes for Not Even Past, “[Demnig] thought the stones would encourage ordinary citizens to realize that Nazi persecution and terror had begun on their very doorsteps."

While Demnig installs every single Stolpersteine himself, he does not work alone. His project, which stretches from Germany to Brazil, relies on the research of hundreds of outside volunteers. Their efforts have not only helped Demnig create a striking memorial, but have also helped historians better document the lives of individuals who will never be forgotten.
