DID YOU KNOW THAT BONDAGE HAD ITS BEGINNINGS IN AMERICAN EARLE DICKSON’S KITCHEN?

When American Earle Dickson married in 1917, he discovered that his new bride Josephine was so clumsy in the kitchen that she cut herself umpteen times a day. Being a solicitous husband, Dickson I would rush to her aid with gauze and sticking tape. Soon, Dickson thought of a better idea. He placed small strips of gauze in the centre of the pieces of sticking tape and then lined the tape with crinoline (a stiff fabric) so that it wouldn’t stick to itself. He re-rolled the tape so that Josephine could unwind and cut off whatever she needed. Dickson worked at Johnson & Johnson, which produced cotton and gauze bandages for hospitals and the military. They were impressed with his idea, but the first versions of the bandage they made did not sell very well because they were too big.

Eventually Band-Aid was popularised by distributing them free to Boy Scouts. The company also began machine-cutting them in different sizes in 1924. By 1939, Band-Aid was sterilised, and in 1958, a completely waterproof version was in the market. Today, the company sells millions of dollars worth of the little sticking plasters every year.

HOW DID WRIGHT BROTHERS INVENTED THE AIRPLANE?

The Wright brothers need no introduction. Best known for achieving the first powered heavier-than-air craft flight, the Wright brothers obtained the patent for a “Flying Machine” on May 22, 1906.

The names of Wilbur Wright and Orville Wright will forever be intertwined with the history of flying machines. For, the Wright brothers were the first to achieve the flight of a powered heavier-than-air craft.

The elder of the two, Wilbur, was born in 1867 and was the third child in the Wright family. Orville was the sixth of seven children that his parents had. The seeds for an idea about flying were sown when Wilbur and Orville were still two young boys.

A toy that inspires

Their mother gave them a toy helicopter to play with. This little piece of wood that had two rubber bands to turn a propeller laid the foundation for a lifetime’s work.

Drawn towards flying, the Wright brothers spent plenty of time observing birds in flight. This allowed them to notice that lift was created when birds soared into the wind and the air flowed over the curved surface of their wings. They use this knowledge to build kites, which they even sold to their friends.

Cycling to aviation

As avid cyclists, Wilbur and Orville owned a bicycle shop as adults. Despite the fact that they had less than 10 years of combined high school education, the experience of building bicycles provided them the understanding of early engine design – be it using chains, sprockets, or ball bearings.

Years of riding a bicycle gave them ideas as to how they could control and balance an aircraft. Add to this the countless hours that they had spent observing flight in nature and they had the necessary knowledge and interest to get started.

By 1899, the Wright brothers ventured into flying. Between 1900 and 1902, they researched every aspect of flight, from roll, pitch, and yaw to the rudder, elevator, and performance of the wing. In order to test the aerodynamic qualities of wing models, they even developed the first wind tunnel. The brothers also worked on their own piloting skills by making over a thousand flights on a series of gliders at Kitty Hawk, North Carolina.

Master a control system

Their years of trial and error allowed them to master their glider in all three axes of flight: pitch, roll, and yaw. While the pitch was operated by a forward elevator, their breakthrough discovery included the simultaneous use of roll control with wing-warping and yaw control with a rear rudder.

Even though they had just started conducting experiments with propellers and begun to build their own engines, they applied for a patent in March 1903 for their control system. They were granted U.S. Patent 821,393 for a “Flying Machine” on May 22, 1906. This patent is significant as it laid down a useful and modern means of controlling a flying machine, regardless of whether it was powered or not.

Not ones to be kept waiting, the Wright brothers had already made the first free, controlled, and sustained flights in a powered, heavier-than-air craft on a chilly day at Kitty Hawk, on December 17, 1903. With just a handful of others witnessing history, Orville stayed 12 seconds in the air and flew 120 feet in the first trial at 10.35 a.m. In the fourth and final trial of the day, Wilbur achieved the longest flight of 59 seconds in the air and reached a height of 852 feet. In a little over 100 years since then, human beings have flown farther and faster than ever before, and continue to progressively get better at it.

What did Peter Henlein invent?

Peter Henlein, a locksmith from Nuremburg, Germany, is considered as the inventor of the modern day watch. He was one of the first craftsmen to make small ornamental Taschenuhren, portable clocks worn as pendants or attached to clothing, which were regarded as the first watches. The Pomander Watch is one of the world’s earliest known portable timepieces and is thought to have been made by Henlein in 1505.

Peter Henlein was born in 1485, and very little is known about his early life. It is most probable that he became apprentice as a repair man and locksmith. His appearance in history books start on September 7, 1504 after he was involved in a brawl in which his friend and fellow locksmith George Glaser was killed. Peter immediately went to the local Franciscan monastery where he found safety. Four years later he returned to the Nuremberg where he became one of the most famous locksmiths, who was especially praised for his ability to create small spring-powered brass clock which were then very rare and expensive. With such popularity, it was not strange that local and distant nobility contacted him on regular basis, demanding ever more beautiful and smaller clock designs. As far historical records are concerned, Peter’s first clock was made in 1510, and by 1541 he was well known for his craft and has been tasked on building not only small clocks but also big tower clock for Lichtenau castle.

Even though his spring designs were not particular accurate (they could lose several hours during one day’s work) or even portable (with around 3 inches in size, they were more suited to be worn as a pendant than in pocket), clocks that were made by Peter Henlein soon became sensation in Europe scientific circles and later on by general European population.

Today, Peter Henlein is regarded as a father of modern clocks even though he was not the first locksmith that made small clock designs or was responsible for the discovery of key clock component –mainspring. He died in 1547 knowing that his invention will live forever.
