The History of our Lawns (Guest Post)

savannaWhen early humans roamed the African savannas, the short grasses there allowed them to spot both prey and predators from far away. It’s for this reason that some now believe our obsession with manicured lawns actually comes from our genetics – we’re instinctively drawn to surround ourselves with areas of short grass for survival and protection. There could be some truth to that, but for now it’s just stipulation. The more accepted explanation for our well-kept lawns is much, much younger and much more in line with the reason many major trends become norm – status.

In Europe during the 17th century, lawns became widely embraced by royals as a great way to show off their magnificent castles, palaces and manors from afar, and to flaunt their wealth. While today, the sheer size of a lawn can speak to a measure of wealth due to upkeep alone, in those days there was another level to it. In the 1600s, a large lawn told everyone around that the owner was extremely wealthy, not simply because they owned all that land, but because they could afford to keep it essentially unused, rather than farming the land for food. It was this idea that kept lawns in the realm of the wealthy only for a long time; members of the lower classes used their lawns as gardens to help provide for themselves and their families.

It wasn’t until the mid 19th century that lawns began to become more desirable in America. Magazines and books brought images of lavish European lawns back across the Atlantic, and they were soon essential for any truly beautiful home. While still only affordable to the wealthy, advancements in technology soon changed all that.

Push-Mower

The push mower, invented in 1870, allowed anyone who owned property to create a lawn of their own. By the time American suburbs exploded in the 1950′s, lawns had fully transitioned from being a status symbol of the wealthy and powerful to the standard for homes everywhere; the idea of “keeping up with the Joneses” made a well-groomed lawn the expectation, not a luxury, for families everywhere.

Lawns continue to be the norm for home landscapes in America today, with almost $30 billion dollars a year spent on lawn care. Even in rural areas, it’s not uncommon to see houses surrounded by a manicured lawn. And just as our ancestors kept fit by running at and from wild animals through the short grass, we too use it for fitness, playing the majority of our sports on fields of grass.

It is safe to say, no matter where it came from, that our obsession with grass and lawns is just a strong as ever.

Pillows Throughout The Ages (Guest Post)

Ancient Egyptian Pillow

A quick Google search for “pillows” will return almost a billion page results and over 30,000 shopping results. Pillows are a universal part of our lives and there are more options than there have ever been, each with its own claim of support and comfort. While the idea of pillows being a soft place to rest your head is not a new concept, it certainly wasn’t its original purpose.

So far as we know, the earliest pillows date back over 9,000 years to Mesopotamia, or modern day Iraq. Formed from stone, the top was carved in a half-moon shape to support the neck. The idea obviously wasn’t comfort, at least not immediate comfort. The basic function of the pillow was to keep the head off the ground and prevent insects from crawling into mouths, noses, and ears. Ancient Egyptians and Chinese also used similar pillows, though each culture had its own reasons for them.

The Egyptians believed that the head was an important spiritual and life center for the body, so pillows and headrests were created to hold and protect it. Most of these pillows, while similar to the Mesopotamians in their curved top, were carved out of wood and reserved mainly for wealthy individuals.

The Chinese on the other hand, created ornately decorated pillows from many materials including wood, stone, bamboo, and even porcelain, bronze, and jade. Though they had the knowledge and ability to create soft pillows, they believed that such pillows stole energy and vitality from the body while one slept and were ineffective at keeping demons away.

Ancient Greeks and Romans used pillows more similar to those we know today–cloth filled with materials such as feathers or straw. By the Middle Ages in Europe, however, pillows had fallen out of favor with many. Many men viewed pillows as a sign of weakness, and their use was primarily limited to pregnant women.

While they did make a resurgence after the Middle Ages, pillows did not become nearly as universal as they are today until the industrial revolution. The improvements in technology made mass production of textiles possible, meaning everyone could sleep with a pillow at night and could even afford decorative pillows for chairs and couches, something that earlier would have been seen as a symbol of high status.

Pillows were created for children to use as weapons.

For such a simple idea, it’s amazing to see that the pillow is still changing – new materials and shapes arise constantly, claiming to provide more support and a better night’s sleep than your old pillow. Though few people likely base their purchases on how well a pillows protects their ears from insects anymore, the pillow has been an important piece of human culture throughout much of our history and continues to be today.

The Convict and the Currents (Guest Post)

On March 29th, 1889, William Kemmler murdered his common-law wife, Matilda Ziegler, with a hatchet. He wasn’t a good guy.

If you’re a believer in a well-balanced universe, or maybe just sort of a gross person, you’ll be delighted to know Kemmler himself was put to death in a congruent, disgusting manner. A year or so later, Kemmler was tried, convicted and slated for the death sentence by means of the New York prison system’s newest form of capital punishment: electrocution.

Thomas-Edison

Thomas Edison

At the very same time, two of America’s most powerful minds were engaged in an ongoing battle that would eventually shape our country’s infrastructure: Thomas Edison and Nikola Tesla were viciously competing to popularize their rival forms of electricity distribution. Edison, the patent holder for the incumbently-used direct current (DC), held a serious contempt for Tesla, the creator of the newer, more dynamic alternating current (AC), and vice-versa.

At a young age, Tesla had immigrated to America to work under the tutelage of Edison himself. Quickly defining himself as a young starlet in the scientific community, Tesla refashioned many of the projects Edison had already posited and developed. After making significant improvements to Edison’s generator and motor systems, Tesla left to start his own company (it’s claimed Edison offered a massive cash prize for Tesla’s innovation, but then claimed it to be a joke and instead proposed a $10 per week pay raise – that was a serious insult to Nikola).

Soon enough, Tesla was up and running with the monetary support of George Westinghouse, a Pittsburgh-based entrepreneur who was looking for an inventive, updated vehicle for electrical power. Tesla secured an American patent for the AC system, and furthered its development while working as a contractor for Westinghouse. The perks of AC distribution were pretty evident from the get-go: it facilitated power delivery over longer distances and at greater speeds. Edison’s direct current, however, still owned merit. Not only was it the preferred choice of the era’s metropolitan hubs, it was also a fair bit simpler for the average consumer.

Kemmler, however, wasn’t your average consumer. He was a murderer who was probably less than concerned over two currents’ discrepancies once he found out he was to be removed from society on a permanent basis. As part of a smear campaign, Edison promoted Kemmler’s electrocution to be carried out via alternating current, rather than his own direct current, as a way to prove that Westinghouse and Tesla were creators of murderous, unsafe electrical current which couldn’t stack up to his own.

Thanks to a few connections and financial backers who involved themselves with the New York justice system, Edison got his wish. On August 6th, 1890 Kemmler was put to death by AC in one of the most painstaking, inhumane executions from modern history. It lasted eight minutes and required two attempts, since the first bout had only used enough voltage to do little more than slowly burn his flesh and leave him unconscious, but still breathing.

Westinghouse, repulsed, commented, “They would have done better using an axe.” But in spite of seeing his name attached to the botch, the American public soon adopted the AC system as its preferred mode of power transmission thanks to its viability over long distances. DC, however, is still employed today in smaller, closed systems which are better served by its attributes. In fact, much of our current-day focus centers on using the two in tandem, or converting one to the other in order to maximize efficiency.

It’s a shame Tesla and Edison couldn’t live to see the maturation and partial reconciliation of their duel. As for Kemmler, he shouldn’t have to worry much about electric currents anymore. I’m relatively sure that hell is powered by furnace.

The History of the Chainsaw (Guest Post)

doctors-invented-chainsawsBig, bushy beards, red flannel shirts, and suspenders. The stereotypical image of the lumberjack is something that many people know. The lumberjack has two standbys in his arsenal of tree removal: the ax and the chainsaw.

The evolution of the ax makes enough sense just by looking at it – the wedge with its sharpened edge can easily be placed at the end of the long line of primitive carving tools from centuries and millennia before. But what about the chainsaw? How did such a strange tool come about?

Believe it or not, the modern chainsaw actually has its beginnings in medicine. John Aitken and James Jeffray were both Scottish doctors who independently invented the same basic tool in the 1780′s for the purpose of cutting not wood, but bone.

The hand saw consisted of a chain with serrated links on one side, running between two handles. One handle would be replaced with a curved needle, passed through the soft tissue around the bone, at which time the handle would be replaced and sawing could begin.

It wasn’t until the 1830′s that this design was expanded on into something more closely resembling a modern chainsaw. Bernhard Heine, a German doctor, closed the loop of the serrated chain and created a hand-cracked bone saw. Despite having created a basic, hand powered version of our modern-day chainsaw, it took nearly another century before the chainsaw as we know it was created.

Naturally, the idea was then applied for other solutions and used for more common applications, like cutting down trees.  The patent for the first electric chainsaw was awarded to Andreas Stihl in Germany in 1926. His first chainsaw weighted 140 pounds and required two men to operate it and because of the onset of the Great Depression, adoption of chainsaws was slow.

In 1927 another German, Emil Lerp, introduced the first gasoline powered chainsaw (Stihl followed with his version in 1929), though it suffered many of the same problems as Stihl’s, weighing in at 125 pounds and only usable by two men at a time.

Both men started companies to produce and sell their inventions. Lerp started his company, Dolmar, and Stihl started his company STIHL. STIHL still produces chainsaws to this day, though it was acquired by the Japanese company Makita in 1991.

Andreas Stihl’s company, despite the slow start in the 20′s, remains the top producer of chainsaws in the world to this day. Stihl’s invention is undoubtedly used by flannel-wearing lumberjacks and arborists everywhere. Today, the chainsaw is still the most dependable tool in the logging and tree care service industry.

The Emergence of Trademarks Throughout History (Guest Post)

trade·mark noun \-ˌmärk\

1 : a device (as a word) pointing distinctly to the origin or ownership of merchandise to which it is applied and legally reserved to the exclusive use of the owner as maker or seller

While the legal guidelines and implications of trademarks are fairly well documented in history, the basic idea of trademarks cannot be traced back to any single point in time, it is something that has grown and developed for as long as civilization, if not longer.

An example of a merchants’ mark.

The one condition that had to exist for the emergence of trademarks was that of commercial goods. As goods were produced and exchanged for money, competition and quality became much more prominent and important than in earlier barter systems.

Many artifacts from Greek and Roman ruins have displayed what are known as potters marks, which were used in those time to identify who (or where) the pot came from, and craftsmen of all kinds would mark their created goods. While these early markings likely bore no legal implications like our trademarks today, they were the essential first step to the trademark law of our time.

Some marks also arose to prove ownership of goods, rather than just their source. “Merchants marks” emerged in the 10th century and have been used ever since. Just as a modern day rancher may brand his animals, merchants marked their goods so that, if they were looted by pirates for example, they could prove their ownership and reclaim them.

Because of the competitive nature that led to these marks, a certain level of complexity was essential to ensure a unique symbol. There were, of course, issues and disagreement, and while some trademark cases had been brought around the world prior to 1803, it wasn’t until that year that France passed the “Factory, Manufacture and Workplace Act” an early (and the first) predecessor to modern trademark law, which made it illegal to pass someone else’s mark as one’s own.

Since then, countries all over the world have created, updated, and adopted regulations and practices to track and control trademarks. The United States passed its first federal law protecting trademarks in 1870, but it was not the last – even today there are still changes to the laws in reaction to our current world.

The advent of television had a massive effect on trademarks, as the medium allowed for innumerable products to reach users in their home. As television spread in the 1950s, the amount of trademark applications to the Patent Office skyrocketed.

Just a simple line, yet, no mistaking its owner.

Today, the biggest challenge facing the control of trademarks is the internet. The global nature of the internet with its many users has made the transfer of information (and therefore infringement) incredibly easy and fast and created a single, global market which can lead to conflicting claims on marks.
