The world is filled with inventions that have shaped the modern world as we know it. From the first power-driven aeroplane invented by Wilbur and Orville Wright to the creation of the telegraph and Morse code by Samuel Morse, these inventions have paved the way for modern tools and technology. Some inventions are the result of teamwork, while others are the brainchild of individual inventors, scientists, and engineers. The measurement of time, for instance, has a long history, with ancient civilisations using water clocks and sundials to tell the time. Today, we continue to build upon these inventions and ideas, creating new innovations that will shape the future.

What You'll Learn
Who invented the lightbulb? — Thomas Edison
While Thomas Edison is often credited as the inventor of the lightbulb, several other inventors played a role in its creation. The development of the lightbulb was a cumulative effort that built on the work of previous inventors.
The story of the lightbulb began long before Edison's time. In 1799-1800, Italian physicist Alessandro Volta developed the first practical method of generating electricity with the voltaic pile, which is considered one of the earliest forms of incandescent lighting. Humphry Davy built upon Volta's work in 1802, using the voltaic pile to create the world's first electric lamp, known as the "electric arc lamp." However, this early lamp shone too brightly and burned out quickly. In 1835, James Bowman Lindsay, and later in 1840, Warren de la Rue, expanded on Davy's idea to create a light source comparable to that of a candle. De la Rue's device used a thin metal strip made of a metal with a high melting point, encased in a glass bulb with the air evacuated, resembling the modern lightbulb.
Other inventors also contributed to the development of the lightbulb. In 1878, Joseph Swan, a Sunderland-born chemist, created the first successful incandescent filament electric lamp and gave public demonstrations of it in 1878 and early 1879. Swan's lamp used carbonised cotton thread, which produced superior results in light longevity. Around the same time, Edison was also working with cotton thread filaments. Edison's combination of thin carbon filament design and improved vacuum pump technology made him the first to develop a commercially viable lightbulb.
Edison's contribution to the electric lighting system was significant. He modelled his lighting technology on the existing gas lighting system and demonstrated that electricity could be distributed from a centrally located generator. He also focused on improving electricity generation and developed the first commercial power utility. Edison's work on the lighting system and his ability to commercialise the lightbulb led to him being widely credited as the inventor.
However, it is important to recognise the contributions of other inventors who paved the way for Edison's success. The lightbulb is a testament to the cumulative efforts of numerous inventors and scientists over almost two centuries.

Who invented the telephone? — Alexander Graham Bell
The telephone is considered one of the most influential inventions of the Victorian era. Scottish-born Canadian-American inventor, scientist, and teacher Alexander Graham Bell is credited with inventing the first practical telephone. He was born on March 3, 1847, in Scotland, and moved with his family to England in 1865 and Canada in 1870. In 1871, he filed a caveat for his design of a talking telegraph.
Bell's work on the telephone was influenced by his family background. His father, grandfather, and brother were all associated with work on elocution and speech, and his mother and wife were deaf. This influenced Bell's career choice as a teacher of the deaf. He taught speech to deaf students and also invented and improved several electrical technologies, including hearing devices. His research on hearing and speech further led him to experiment with hearing devices, which eventually culminated in his invention of the telephone.
On March 7, 1876, Bell was granted US Patent Number 174,465 for an "Improvement in Telegraphy". There is some controversy regarding the invention of the telephone, with some sources claiming that Bell's work was influenced by Italian immigrant Antonio Meucci, who began developing the design of a talking telegraph or telephone in 1849. Meucci filed a caveat for his design in 1871 but could not renew it due to financial hardships. Elisha Gray, an American inventor, and German physicist Johann Philipp Reis are also sometimes cited as candidates for the invention of the telephone.
Bell's telephone design was the first to be patented, and he continued to work beyond this patent to create a working device. On March 10, 1876, Bell successfully transmitted vocal sounds over his telephone, saying to his assistant Thomas Watson, "Mr. Watson, come here, I want to see you!". This was the first successful telephone conversation, and Bell's invention revolutionized the way we communicate.

Who invented the World Wide Web? — Tim Berners-Lee
Tim Berners-Lee invented the World Wide Web in 1989 while working at CERN, the European Particle Physics Laboratory. He wrote the first web client and server in 1990, and published the first web page for CERN users in December 1991. Berners-Lee's creation of the Web was motivated by a desire to make the lives of CERN's several thousand scientists easier by linking their project information through one extended network of computers.
Berners-Lee's parents were both mathematicians and computer scientists, and he built his own computer out of an old television set while at university. After graduating with a first-class BA in physics from the Queen's College, Oxford, he worked as an engineer at the telecommunications company Plessey in Poole, Dorset. He then worked as an independent contractor at CERN from June to December 1980, during which he proposed a project based on the concept of hypertext to facilitate information sharing and updating among researchers. He built a prototype system named ENQUIRE to demonstrate his idea.
After leaving CERN in late 1980, Berners-Lee worked at John Poole's Image Computer Systems, Ltd, in Bournemouth, Dorset, for three years, gaining experience in computer networking. He returned to CERN as a fellow in 1984, and in 1989, he saw an opportunity to join hypertext with the Internet, leading to the creation of the World Wide Web.
Berners-Lee has received numerous awards and honours for his pioneering work, including being knighted by Queen Elizabeth II in 2004 and receiving the A.M. Turing Award, often called "computing's Nobel Prize", in 2016. He has also been inducted into the Internet Hall of Fame and was named one of Time magazine's 100 Most Important People of the 20th Century.

Who invented the airplane? — Orville and Wilbur Wright
The Wright brothers, Orville and Wilbur, are credited with inventing the first powered and controlled airplane. They achieved the first successful piloted flight of a heavier-than-air powered aircraft on December 17, 1903, in Kitty Hawk, North Carolina. Orville piloted the plane, later named the Wright Flyer, for 12 seconds, covering a distance of 120 feet (36 meters).
The Wright brothers' interest in aviation began at a young age when their father brought home a small model helicopter. They were fascinated by its mechanics and developed a lifelong passion for aeronautics and flying. As they grew up, they experimented with mechanical objects and began to design their own flying machine. They drew on ideas from their earlier experiments with kites, toy helicopters, printing machines, and bicycles.
The Wright brothers took a different approach from other experimenters of their time. Instead of focusing on developing powerful engines, they concentrated on creating a reliable method of pilot control. They constructed a small home-built wind tunnel, which allowed them to gather more accurate data and design more efficient wings and propellers. Their system of aircraft controls made fixed-wing powered flight possible and remains the standard for all types of airplanes today.
The Wright brothers' first successful flight was witnessed by four other men, one of whom took pictures. However, the event received little attention from newspapers, and it was almost five years before they gained fame. In 1908, Wilbur went to France, where he gave demonstration flights and garnered a much more receptive audience. A French company agreed to manufacture the Wright brothers' flying machine, and they began selling their airplanes in Europe. The brothers became wealthy businessmen, fulfilling contracts for airplanes in both Europe and the United States.

Who invented Morse code? — Samuel Morse
Morse code is a telecommunications method that encodes text characters as standardised sequences of two different signal durations, called dots and dashes, or dits and dahs. It was named after Samuel Morse, one of the early developers of the system, who was an American inventor and painter.
Born in Charlestown, Boston, Massachusetts, in 1791, Morse contributed to the invention of a single-wire telegraph system in the 1830s. He developed the concept of a single-wire telegraph after witnessing experiments with electromagnets while returning to America from Europe by ship in the early 1830s. He was intrigued by the idea of using electricity to transmit messages over long distances.
Morse code was developed alongside the telegraph and assigned a set of dots and dashes to each letter of the English alphabet, allowing for the simple transmission of complex messages across telegraph lines. The code was necessary to help translate the marks on the paper tape created by the telegraph machine into readable text messages. Morse developed the first version of this code, which initially included only numbers. His assistant and partner, Alfred Vail, soon expanded it to include letters and a few special characters, such as punctuation marks.
The original Morse code used patterns of dots and spaces to represent some of the letters, while the International Morse Code, devised by a conference of European nations in 1851, uses combinations of dots and short dashes for all letters. The International Morse Code also uses dashes of constant length, rather than the variable lengths used in the original Morse Code.
