History of Inventions
For many people, elevators are one of those parts of everyday life that you just don't think about. They get in, push a button, get off and go about their day without giving it a second thought. But elevators at not only mechanically fascinating, they have also played a major role in shaping our modern day society.
The guitar is one of the most popular instruments in modern music. It is the core instrument of genres like rock and blues and it is beloved by music aficionados and hobbyists alike. What few know, though, is that the modern guitar is a relatively recent invention. The evolution of the guitar is certainly an interesting journey, starting before written language and developing through the modern-day. A story that's as much about engineering and innovation as it is music, the tale of the guitar starts in the distant past.
Bicycles are a wonder of modern technology, persisting to this day despite there being many other more efficient means of transport. While being fun and easy to use are its main appeal, the bicycle also sports a long history of innovation and evolution that brought it to where it is today.
It is widely accepted that crude blades made from stone were among the first tools to be developed & used by mankind. So it comes as no surprise that the first surgical instrument would be a variation of the blade, that fundamental tool which found ubiquitous use in so many of man's earliest activities such as hunting, preparing food, making art, crafting other tools and of course our earliest attempts at medicine & surgery.
The barber chair has been a fixture in barbershops for more than a century and a half, with engravings from as far back as the Civil War era showing designs not entirely unlike those still in use today.
However, the barber chair truly came to prominence around the turn of the century, when a number of patented inventions by an enterprising young man named Ernest Koken led to the basic chair design that is still in use today. Koken barber chairs dominated the first half of the century, and they remain popular today both as collectible antiques and as modern, contemporary chairs.
