INVENTIONS
From 1936 to 1903 the development of a series of inventions was essential for the continuation of human evolution. They were improved over the years and are still used today in their optimum form. -
DEVELOPMENT OF THE ELECTRIC TELEGRAPH
The American, Samuel Morse, developed an electric telegraph between 1832 and 1836 in United States. This device using electric signals and a system of dots and dashes, the Morse Code (created by Samuel), allowed people to communicate over long distances, connected by wire, instantaneously. In 1844, Morse transmitted his first message with the telegraph among two cities, Washington and Baltimore. -
PATENT FOR DYNAMITE
The Swedish Alfred Nobel patented the dynamite in Great Britain in 1867. He added an absorbent substance made of algae to make stable the nitroglycerine, as it was dangerous, discovered by Ascanio Sobrerio. The dynamite was used in demolitions and to make tunnels in an easier way in mining and on railways. Unfortunately, it was also used in wars. Later, he created the detonator. -
PATENT FOR THE TELEPHONE
In 1876, the Irish, Graham Bell patented the telephone at Washington. However, he had problems with Antonio Meucci, who invented the telephone many years before. And also with Elisha Gray, who went a few hours before to patent a similar device to Bell’s one. The telephone changed the way of transmission of information, as it used sound waves, unlike the telegraph. -
TEST OF THE FIRST LIGHT BULB
Thomas Alva Edison, tested in his laboratory in Menlo Park (New Jersey) his light bulb, shining more than half a day. He did not invented it, but improved the designing of previous light bulbs, making the filament of carbonized bamboo. With this upgrade, the bulbs were cheaper, more practical and the most important thing, they were shining more time. In 1880, he received the patent. -
FIRST CAR WITH INTERNAL COMBUSTION ENGINE
Karl Benz made the Benz-Patent Motorwagen, the first car with an internal combustion engine in 1886, in Germany. It had three wheels, a maximum speed of 16 "km" ⁄"h" and the engine, it was of four-stroke and had one cylinder and a weight of 100 kilograms. His wife did the first journey with it, from Mannheim to Pforzheim, more than a hundred kilometers. With it, journeys became quicker and more comfortable. -
CINÉMATOGRAPHE
The Lumiere brothers patented the cinématographe in 1895. It was made up of a box with a lens and a 35 millimetre perforated film. The film was rolled by a handle to take the snapshots that made up the sequence, which lasted no more than a minute, and then projected onto a screen. The same year, they did their first screening, at Paris. Whit them, it started the cinema. -
WIRELESS TRANSMISSION ACROSS THE ENGLISH CHANNEL
Marconi patented the Wireless Telegraphy System, a device that transmitted electromagnetic waves without the need for wires. In 1899 he established the first wireless communication between France and England, across the English Channel and, in 1901 across the Atlantic Ocean. In its early days, wireless telegraphy was used to speed up communication between ships during navigation and nowadays, in mobile communications, Internet access or security systems. -
PILOTING THE FIRST POWERED AIRPLANE
In 1903, in Kitty Hawk (North Carolina), Orville Wright completed the first flight on the Flyer, the first powered airplane in History. He flew four times and, in the first one, he was at the air for 12 seconds and went across 36 metres. To make the airplane he observed birds’ flights and based on previous models. This was the first step to travel big distances in a short period of time.
