The First Known Uses of 6 Common Typographic Symbols

Many of the most common symbols on our keyboards have fascinating origin stories. Some, such as the zero, we now take for granted—yet the idea of denoting an absence of value was not present in Western mathematics until introduced from the East. Other symbols, such as the hashtag or at-sign, had a variety of uses until the internet ushered in a new way of communicating and fixed them with the meanings we know today. Below are six examples of the first known usage and subsequent history of some of the most common typographic symbols.

1. AT SIGN // @

The @ (or at-sign) is usually dated to 1536 in a letter from a Florentine merchant, Francesco Lapi, who used it to mean a unit of wine called “amphorae.” But a Spanish researcher claims to have found an even earlier usage in a 1448 document, where the symbol also referred to a unit of measurement (even today, Spaniards call the @ symbol arroba, which is also a unit of weight, and some other Romance languages have similar dual meanings). Either way, the researchers think that the symbol then moved to Northern Europe, where it eventually gained the meaning of “at the price.” Other explanations have also been offered, but whatever the exact root of the symbol, its meaning eventually became known as shorthand for at, and it was generally used in written financial transactions—for example, in noting “Bob sells James 4 apples @ $1.”

The sign had largely fallen out of use by the early 1970s, when computer scientist Ray Tomlinson was working at what is now BBN Technologies, in Cambridge, Massachusetts. Tomlinson, who was working for the government on a forerunner of the internet, was trying to figure out how to address messages sent from one computer to another when he noticed the little-used @ on his computer keyboard, and used it to send a prototype email. This precedent was soon adopted as the internet developed, and the at-sign is now, of course, central to our lives.

2. ZERO // 0

The absence of a value is a complex concept, one that many ancient civilizations struggled with. The idea of a zero ultimately came to the West from the mathematicians of India, where, as in a few other cultures, zero was initially used as a placeholder, for example to indicate a lack of units, as in the number 101.

The earliest surviving usage of a zero in India has been traced to an ancient mathematical text known as the Bakhshali manuscript, which is held at Oxford’s Bodleian Library. In September 2017, radiocarbon dating indicated that the manuscript was produced as early as the 3rd or 4th century—providing us with the first known usage of zero some 500 years earlier than previously thought. As Oxford’s Bodleian Library says, “the symbol in the Bakhshali manuscript is particularly significant for two reasons. Firstly, it is this dot that evolved to have a hollow centre and became the symbol that we use as zero today. Secondly, it was only in India that this zero developed into a number in its own right, hence creating the concept and the number zero that we understand today."

The manuscript itself was discovered buried in a field in 1881 in what is today Pakistan. Written on 70 delicate leaves of birch bark, historians think it represents a training manual for Silk Road traders, teaching them concepts of arithmetic.

3. HASHTAG // #

The origin of the hashtag (or pound sign as it's traditionally known in the U.S.) comes from scribes writing shorthand for the Latin libra pondo, which translates as "pound by weight." The abbreviation they used was lb, which was sometimes misread as 16. So, scribes took to drawing a line through the top of the two letters, which over time developed into the now familiar #. In the 1960s, the pound sign was chosen by Bell Laboratories to be a function key on their newly designed telephone keypad. (The Bell Labs team fondly nicknamed the symbol the “octothorpe,” possibly in honor of athlete Jim Thorpe.) Fast-forward to 2007, when early Twitter users wanted to be able to group and filter their feeds, so developer Chris Messina suggested they appropriate the method used in IRC (Internet Relay Chat) whereby users employed the pound sign or "hashtag" to signpost what they were chatting about. (Programmers knew the symbol as the hash, which was now being used to "tag" content.) This simple method soon caught on, and today the hashtag has become indelibly linked to the rise of social media.

4. ELLIPSIS // …

Originally, periods of silence were marked textually with a series of hyphens, but today the symbol of choice is the , a.k.a. the ellipsis. Dr. Anne Toner of Cambridge University spent years researching the ellipsis and finally discovered what she thinks is its first use—an English translation of Roman dramatist Terence’s play Andria printed in 1588. Although the play used hyphens instead of dots, the general idea caught on rapidly. (Toner notes that although there are only four “ellipses” in the 1588 translation, there are 29 in the 1627 version.) By the 18th century, dots started to replace the dashes, which an assistant professor from Southeastern University suggests may be connected to a medieval piece of punctuation called subpuncting or underdotting, which generally indicated something was incorrectly copied.

5. AMPERSAND // &

The ampersand originated in Latin when the word et (meaning and) was written in cursive script as a ligature (in which one or more letters are written together as a single glyph). One of the earliest examples was found daubed in graffiti on the walls of a house in Pompeii, where it was preserved by the eruption of Vesuvius in 79 CE. By the 8th century the ampersand became a recognizably distinct character, but the word ampersand did not come into use until the late 18th/19th century, when English school children would recite "and per se and" meaning “and by itself means and” to help remember the symbol (per se being Latin for "by itself"). One of the most thorough investigations into the typographic history of the ampersand comes courtesy of German graphic designer Jan Tschichold, who in 1953 published The am­persand: its ori­gin and de­vel­op­ment, in which he collected numerous examples of the ampersand from the 1st century onwards, visually charting its developing form.

6. PLUS SIGN // +

The plus sign used for addition in mathematics likely derives from a shorthand ligature for the Latin et meaning “and” and was probably in use for a long time before a surviving example appeared in print. One candidate for the earliest surviving usage is in French philosopher and polymath Nicole Oresme's Algorismus proportionum, a manuscript handwritten between 1356 and 1361, although scholars debate whether it's a true plus symbol. The first use of a plus sign in a printed book is more definitive, and can be found in a 1489 edition of Johannes Widmann’s Mercantile Arithmetic. Widmann also uses the minus sign for the first time in print in this volume—although both plus and minus signs relate not to addition and subtraction but to surpluses and deficits in business accounting. After this usage, the plus sign began to appear more frequently in German mathematical texts, and first appeared in an English text in 1557 in Robert Recorde’s The Whetstone of Witte—which also introduced the equals sign.

6 Facts About International Women's Day

For more than 100 years, March 8th has marked what has come to be known as International Women's Day in countries around the world. While its purpose differs from place to place—in some countries it’s a day of protest, in others it’s a way to celebrate the accomplishments of women and promote gender equality—the holiday is more than just a simple hashtag. Ahead of this year’s celebration, let’s take a moment to explore the day’s origins and traditions.

1. International Women's Day originated more than 100 years ago.

On February 28, 1909, the now-dissolved Socialist Party of America organized the first National Woman’s Day, which took place on the last Sunday in February. In 1910, Clara Zetkin—the leader of Germany’s 'Women's Office' for the Social Democratic Party—proposed the idea of a global International Women’s Day, so that people around the world could celebrate at the same time. On March 19, 1911, the first International Women’s Day was held; more than 1 million people in Germany, Switzerland, Austria, and Denmark took part.

2. The celebration got women the vote in Russia.

In 1917, women in Russia honored the day by beginning a strike for “bread and peace” as a way to protest World War I and advocate for gender parity. Czar Nicholas II, the country’s leader at the time, was not impressed and instructed General Khabalov of the Petrograd Military District to put an end to the protests—and to shoot any woman who refused to stand down. But the women wouldn't be intimidated and continued their protests, which led the Czar to abdicate just days later. The provisional government then granted women in Russia the right to vote.

3. The United Nations officially adopted International Women's Day in 1975.

In 1975, the United Nations—which had dubbed the year International Women’s Year—celebrated International Women’s Day on March 8th for the first time. Since then, the UN has become the primary sponsor of the annual event and has encouraged even more countries around the world to embrace the holiday and its goal of celebrating “acts of courage and determination by ordinary women who have played an extraordinary role in the history of their countries and communities.”

4. International Women's Day is an official holiday in dozens of countries.

International Women’s Day is a day of celebration around the world, and an official holiday in dozens of countries. Afghanistan, Cuba, Vietnam, Uganda, Mongolia, Georgia, Laos, Cambodia, Armenia, Belarus, Montenegro, Russia, and Ukraine are just some of the places where March 8th is recognized as an official holiday.

5. It’s a combined celebration with Mother’s Day in several places.

In the same way that Mother’s Day doubles as a sort of women’s appreciation day, the two holidays are combined in some countries, including Serbia, Albania, Macedonia, and Uzbekistan. On this day, children present their mothers and grandmothers with small gifts and tokens of love and appreciation.

6. Each year's festivities have an official theme.

In 1996, the UN created a theme for that year’s International Women’s Day: Celebrating the Past, Planning for the Future. In 1997, it was “Women at the Peace Table,” then “Women and Human Rights” in 1998. They’ve continued this themed tradition in the years since; for 2019, it's “Better the balance, better the world” or #BalanceforBetter.

8 Enlightening Facts About Dr. Ruth Westheimer

For decades, sex therapist Dr. Ruth Westheimer has used television, radio, the written word, and the internet to speak frankly on topics relating to human sexuality, turning what were once controversial topics into healthy, everyday conversations.

At age 90, Westheimer shows no signs of slowing down. As a new documentary, Ask Dr. Ruth, gears up for release on Hulu this spring, we thought we’d take a look at Westheimer’s colorful history as an advisor, author, and resistance sniper.

1. The Nazis devastated her childhood.

Dr. Ruth was born Karola Ruth Siegel on June 4, 1928 in Wiesenfeld, Germany, the only child of Julius and Irma Siegel. When Ruth was just five years old, the advancing Nazi party terrorized her neighborhood and seized her father in 1938, presumably to shuttle him to a concentration camp. One year later, Karola—who eventually began using her middle name and took on the last name Westheimer with her second marriage in 1961—was sent to a school in Switzerland for her own protection. She later learned that her parents had both been killed during the Holocaust, possibly at Auschwitz.

2. She shocked classmates with her knowledge of taboo topics.

Westheimer has never been bashful about the workings of human sexuality. While working as a maid at an all-girls school in Switzerland, she made classmates and teachers gasp with her frank talk about menstruation and other topics that were rarely spoken of in casual terms.

3. She trained as a sniper for Jewish resistance fighters in Palestine.

Following the end of World War II, Westheimer left Switzerland for Israel, and later Palestine. She became a Zionist and joined the Haganah, an underground network of Jewish resistance fighters. Westheimer carried a weapon and trained as both a scout and sniper, learning how to throw hand grenades and shoot firearms. Though she never saw direct action, the tension and skirmishes could lapse into violence, and in 1948, Westheimer suffered a serious injury to her foot owing to a bomb blast. The injury convinced her to move into the comparatively less dangerous field of academia.

4. A lecture ignited her career.

In 1950, Westheimer married an Israeli soldier and the two relocated to Paris, where she studied psychology at the Sorbonne. Though the couple divorced in 1955, Westheimer's education continued into 1959, when she graduated with a master’s degree in sociology from the New School in New York City. (She received a doctorate in education from Columbia University in 1970.) After meeting and marrying Manfred Westheimer, a Jewish refugee, in 1961, Westheimer became an American citizen.

By the late 1960s, she was working at Planned Parenthood, where she excelled at having honest conversations about uncomfortable topics. Eventually, Westheimer found herself giving a lecture to New York-area broadcasters about airing programming with information about safe sex. Radio station WYNY offered her a show, Sexually Speaking, that soon blossomed into a hit, going from 15 minutes to two hours weekly. By 1983, 250,000 people were listening to Westheimer talk about contraception and intimacy.

5. People told her to lose her accent.

Westheimer’s distinctive accent has led some to declare her “Grandma Freud.” But early on, she was given advice to take speech lessons and make an effort to lose her accent. Westheimer declined, and considers herself fortunate to have done so. “It helped me greatly, because when people turned on the radio, they knew it was me,” she told the Harvard Business Review in 2016.

6. She’s not concerned about her height, either.

In addition to her voice, Westheimer became easily recognizable due to her diminutive stature. (She’s four feet, seven inches tall.) When she was younger, Westheimer worried her height might not be appealing. Later, she realized it was an asset. “On the contrary, I was lucky to be so small, because when I was studying at the Sorbonne, there was very little space in the auditoriums and I could always find a good-looking guy to put me up on a windowsill,” she told the HBR.

7. She advises people not to take huge penises seriously.

Westheimer doesn’t frown upon pornography; in 2018, she told the Times of Israel that viewers can “learn something from it.” But she does note the importance of separating fantasy from reality. “People have to use their own judgment in knowing that in any of the sexually explicit movies, the genitalia that is shown—how should I say this? No regular person is endowed like that.”

8. She lectures on cruise ships.

Westheimer uses every available medium—radio, television, the internet, and even graphic novels—to share her thoughts and advice about human sexuality. Sometimes, that means going out to sea. The therapist books cruise ship appearances where she offers presentations to guests on how best to manage their sex lives. Westheimer often insists the crew participate and will regularly request that the captain read some of the questions.

“The last time, the captain was British, very tall, and had to say ‘orgasm’ and ‘erection,’” she told The New York Times in 2018. “Never did they think they would hear the captain talk about the things we were talking about.” Of course, that’s long been Westheimer’s objective—to make the taboo seem tame.
