History Undusted: The Evolution of the Zipper

zipperA zipper is something one rarely thinks about until it breaks.  It’s something we use every day, from trousers to jackets to purses to zip-lock bags.  Yet the actual modern zipper has only been around 101 years!  The idea began forming as a practical design in 1851 in the mind of Elias Howe, who patented an “Automatic Continuous Clothing Closure” (no wonder that name never caught on).  He was not a marketing whiz, and the idea petered out.  At the 1893 Chicago World’s Fair, a device designed by Whitcomb Judson was launched but wasn’t very practical, and again, it failed to take off commercially.  In 1906, a Swedish-American electrical engineer by the name of Gideon Sundback was hired by (and married into) the Fastener Manufacturing and Machine Company (Meadville, PA), and became the head designer.  By December 1913, he’d improved the fastener into what we would recognize as the modern zipper, and the patent for the “Separable Fastener” was issued in 1917.  In March of that year, a Swiss inventor, Mathieu Burri, improved the design with a lock-in system added to the end of the row of teeth, but because of patent conflicts, his version never made it to production.

The name “zipper” was coined by the B.F. Goodrich Company in 1923, when they used Sundback’s fastener on a new type of rubber boot.  When they first came into production, zippers were mainly used on boots and tobacco pouches, only making it onto leather jackets in 1925 (produced by Schott NYC), trousers in 1937 (beating out the traditional button method for men’s trousers).  The next time you use a zipper, stop and think about what you would have had to use 100 years ago!

And in the meantime, here are a couple idioms that have arisen using “zip” or “zipper” or which refer directly to that imagery:

Zip it (up) – close your mouth

Zip your lip/mouth

Zip Your Lip

Euphemisms about undone zippers are numerous; here are a few of the better ones (IMHO):

Barn/stable door’s open

It’s six-thirty

Bombay’s open

Fly time

What do birds/airplanes do?

You’re advertising

Flag’s at half-mast

Front/trap door’s open

Your horse/colt’s gonna bolt

Mind the gap

Zip code

XYZ (PDQ) – “Examine Your Zipper (pretty darn quick)” – Your zipper is open

History Undusted: Celebrating Amalie Noether

The celebration of this relatively unknown figure highlights her brilliance in the face of staunch sexism.  As a woman, I still feel sexism today, though it’s far more subtle – the glass ceilings still need to be broken through, and the duplicity of definition needs to be redressed (name any male characteristic, and often the negative reverse is applied to women, whether stated or subconscious; e.g. a man may be assertive, but if a woman shows the same spirit, she’s often labelled as aggressive). Though they paved the way for a better path for many women, Amalie and her female contemporaries faced brick ceilings and walls.

Born in 1882 in Erlangen, Germany, Amalie was born into a family of brilliant mathematicians, yet had to beg to be allowed to study at University; when she aced her audited courses, they only reluctantly acknowledged her achievements. She was an unpaid, unsung heroine for years, yet Einstein himself referred to her as “the most significant creative mathematical genius thus far produced.”  To read more about her story, and details of her scientific breakthroughs, please click on the image below.

History Undusted: The Shilling

1 Shilling front

Numismatics is an interesting field, and in doing research for the Northing Trilogy, I wanted to know just what currencies would have been used at the time (1750s, England), and what the value of the currencies were:  How much could be purchased or earned?  Would a Stirling pound have made a pauper a land owner or not?  That brought me to the current book I’m reading, called “The Splendid Shilling” by James O’Donald Mays.  Here are a few bits and bobs:

The Shilling was a form of currency used in Britain up until the 1970s; even after that, the coins continued in circulation as smaller denominations (1 shilling was 5 p, and 2 shilling was 10p) until 1990, when it was demonetized.  I remember using them until they were phased out and replaced by the smaller coins of 5p and 10p values, and I kept a few for my coin collection.  One shilling coins were called “bobs”, and that led to programs such as “bob-a-job” fund raisers by the boyscouts, starting in 1914.  Two shillings were known as Florins, or “two-bob bits”.

1 Shillings reverseThe word shilling most likely comes from a Teutonic word, skel, to resound or ring, or from skel (also skil), meaning to divide.  The Anglo-Saxon poem “Widsith” tells us …”þær me Gotena cyninggodedohte; se me beag forgeaf, burgwarenafruma, on þam siexhund wæs smætes goldes, gescyred sceatta scillingrime...”  “There the king of the Goths granted me treasure: the king of the city gave me a torc made from pure gold coins, worth six hundred pence.”  Another translation says that the gold was an armlet, “scored” and reckoned in shilling.  The “scoring” may refer to an ancient payment method also known as “hack” – they would literally hack off a chunk of silver or gold jewellery to purchase goods, services and land, and the scoring may have been pre-scored gold to make it easier to break in even increments, or “divisions”.  From at least the times of the Saxons, shilling was an accounting term, a “benchmark” value to calculate the values of goods, livestock and property, but did not actually become a coin until the reign of Henry VII in the 1500s, then known as a testoon.  The testoon’s name and design were most likely inspired by the Duke of Milan’s testone.

History Undusted: The Origins of Basketball’s Jump Shot

Everyone who’s seen basketball has seen a jump shot; but at some point in the past, someone came up with the idea of becoming airborne over the basketball court when no one else had ever done it before. And that someone was Kenny Sailors. An unassuming elderly man now, if you passed him on the street, you’d never know that his way of thinking changed a sport forever. Click on the image below to hear his story.

The Art of Diatom Microscopy

 

John Quekett.jpg

John Quekett

Recently, I came across an interesting piece of history:  During the Victorian Age, people were fascinated with nature, excursions, and technology.  Microscopes were becoming accessible to the rising middle classes of England, and one man, John Quekett, was fascinated by both microscopes and phytoplankton. He wrote a book called Practical Treastise on the Use of the Microscope, which was a hit among the Victorians, and they began discovering a hidden world of tiny creatures known as plankton and diatoms.

 

Plankton is what makes the ocean waters green, or aqua-blue – the differences are not only the sand or rock colour of a particular region, but also the density of microscopic life in the water. The denser the population, the lower the visibility. A teaspoon of seawater can contain a million living creatures. Regardless of their size, they underpin the marine foodchain, and indeed, all life on earth: Diatoms, which is the most common type of plankton, number in the trillions (there are over 100,000 known species to date), produce more than 20% of all oxygen on earth, and contribute nearly half of the organic life in the oceans. The shells of dead diatoms can cover the ocean bed as deep as half a mile in places, and they fertilize the Amazon basin to a tune of 27 million tons annually.

The Victorians knew very little of all that; they were at the dawn of discovery, and modern sciences owe a lot to those early intrepid explorers – women and men who braved the weather, cliffs and oceans in (heavy skirts and) leather shoes to discover, explore, and appreciate nature.  Not only did they discover it, but they began making beautiful arrangements from the various shapes – they would display their microscopic artwork to friends, much like we might look through someone’s holiday photos today.  These were known as Rosette Slides, and there is still one famous artist keeping this art form alive today: Klaus Kemp, known as the Diatomist. Here are just a few of his masterpieces; to see more, just google his name. The two links in this article will take you to two short videos on the topic.  Enjoy!

History Undusted: The Immortal Life of Henrietta Lacks

Henrietta Lacks, Immortal HeLa CellsIf you’ve ever taken any medication stronger than an aspirin and benefited from it, chances are that you owe your thanks to an African American woman who never lived to hear your tale.

Born in 1920 as Loretta Pleasant, when her mother died giving birth to her 10th child and the father could not support the family, the children were divided among relatives to be raised.  Loretta, who became known as Henrietta, was sent to live with her grandfather, Tommy Lacks, who lived in a two-storey log cabin (former slave quarters) on the tobacco plantation of her white great-grandfather.  After having five children with her first cousin, whom she married after their first two children were born, she died at the age of 31 of cervix cancer.

What is most remarkable about her life is something she never knew:  During the diagnosis of her cancer, done at Johns Hopkins (the only hospital near her home that would treat black patients), her doctor, George Gey, was given samples of her cervix for biopsies. Before this time, any cells cultured from other cells would die within days.  Dr Gey discovered that her cells were remarkably durable and prolific.  A selection of her cells was isolated and cultured (without her knowledge – back then, permission wasn’t necessary for what was considered tissue waste) into the immortal cell line that became known as HeLa Cells; they are still in use today worldwide, being the first human cells to be cloned successfully, in 1955.

HeLa cells are so prolific that if they land in a petri dish, they will take over; they have been used to create the vaccine against Polio, in research for AIDS, gene mapping, cancers and countless other projects; to date, scientists have grown over 50 million metric tonnes of her cells*, and there are nearly 11,000 patents involving these cells.  Her name should be known, and as the godmother of biotechnology, her history deserves to be undusted!

For a fascinating book on this topic, see The Immortal Life of Henrietta Lacks, by Rebecca Skloot. I’ve read it, and had trouble putting it down!

History Undusted: Hnefatafl (Viking Chess)

hnefatafl

Hnefatafl (meaning King’s Table, aka “Viking Chess”) is a board game that originated in Northern Europe; the oldest board found to date was located in Denmark, dated to ~ 400 BC. Because no written history of that period for northern Europe exists, apart from runic inscriptions on stone, wood, and bone, the rules of this game had to be recreated, so there are no hard and fast rules agreed upon by those who play it.  It is far older than chess, which originated in northern India in the 6th century AD and spread to the rest of the world through Persia.

In Hnefatafl, the game is played on a square board (as pictured). There are five spaces on the board that are considered special: The space in the centre of the board is the ‘Throne’ space, and the four corner spaces are the escape points for the King.

Unlike most modern board games, Hnefatafl does not start with even-strength sides (as in chess). The two sides are divided into attackers and defenders; in the illustration, the pieces along the edges of the board are the attackers, and those in the centre are the defenders. The objective of the attacker is to capture the king (centre). The objective of the defenders is to protect the king long enough for him to escape.

The board shown above is a modern version; but online, I’ve seen a wide variety of boards, from draw-bags of leather with stone pieces to wooden blocks on a large outdoor board.  I’m certain that the travelling Norse, who loved board games, word games and competitions of any sort, would have made do with whatever was at hand and would have also had travel versions of their favourite games, just like we do today.

For further information, check out the Wikipedia article, or see the rules and how to play the game here.

Stinging Nettles: A Weed with a Bad Rap and a Great Sap!

stinging nettleStinging nettles have gotten a bad rap, in my opinion.  True, they’ve not done much to endear themselves to hikers who get stung as they walk through undergrowth; but if you can get beyond first impressions, you’ll discover one of the power-packs of nature!  Stinging nettles have been around for thousands of years, and recipes for their use have been around for probably just as long. A fast-growing herb related to the mulberry, they grow everywhere (especially well in northern climates), and the list of their benefits reads more like a “Who’s Who” of remedies, from prostate, arthritis, blood pressure (it balances both high and low!), to iron and mineral deficiencies.  The younger the leaves, the more power and goodness they still have in them, so pick the top 4 to 6 new leaves for the best results.

It can be eaten raw straight off the plant:  “Taco”-fold the leaf by gripping it on the underside near the base of a young leaf and nipping it off with a pinch of the fingers, pop it in the mouth and chew; the juices from the leaf itself will neutralize any brief sting.  Also, if you’re out on a hike and get stung by the leaves inadvertently, take a leaf as described, chew it up or smash it up in your hand and rub the juices onto the sting area; it will neutralize itself.  It can also be boiled for teas, soups (it boils down like spinach, so you’ll need a lot more than you think you will), or blended into a pesto, or pizza sauce; the variety of ways to eat it are endless.  Once the stingers have been neutralized (their own juices will do the trick once released through blending, boiling, or processing in any way needed), its health benefits are unprecedented as a common plant, free to be had!  Just a word to the wise:  If you let it grow in your own garden, eat it as-is or with a light rinse if you’d like; but if you harvest from a public pathway, park or forest, washing it thoroughly is a good idea; where there are humans, there could be traces of herbicides or dogs… need I say more?

Click on the image above for a delicious, quick recipe.  When spring arrives, I’ll be looking for a fresh patch!
