1. The Light Bulb – Thomas Alva Edison
• In 1879, Thomas Alva Edison introduced the first practical incandescent light bulb to replace the hazardous gas lamps providing a reliable, economical and long-lasting source of light,
• Edison’s experimentation led to the discovery of a carbonised cotton thread filament that could emit a glow within a vacuum-sealed glass bulb.
• The light bulb transformed daily human life and living. This invention illuminated homes, workplaces, and public spaces setting the stage for modern electric systems.
• The light bulb also brought about even more inventions, such as electrical appliances, the phonograph, and advanced versions of the light bulb like the LED bulbs.
• The electrical power grids were expanded because of the light bulb. The largest and world’s first electrical power grid was built in 1895 in Niagara Falls.
2. The Telephone – Alexander Graham Bell
• In 1871, Alexander Graham Bell, a Scottish inventor, scientist, and engineer, began developing the harmonic telegraph, enabling simultaneous transmission of numerous messages over a wire.
• By 1875, Bell, alongside his partner Thomas Watson, created a basic receiver that converts electricity into sound.
• In 1876, Bell was granted his telephone patent. Bell’s experiments in transmitting sound over electrical wires resulted in real-time voice communication over long distances. This invention changed the way people communicate, paving the way for the interconnected world we live in today.
• Among his remarkable creations included the metal detector, photophone, graphophone, and audiometer.

3. The World Wide Web – Tim Berners-Lee
• Invented in 1989, by October of 1990, Tim, the inventor had written the three fundamental technologies that remain the foundation of today’s web
  • HTML: HyperText Markup Language. The markup (formatting) language for the web.
  • URI: Uniform Resource Identifier. The “address” is unique and used to identify each resource on the web. It is also commonly called a URL.
  • HTTP: Hypertext Transfer Protocol. Allows for the retrieval of linked resources from across the web.
• His invention transformed businesses and organisations, becoming an integral part of personal and professional lives.
• By 1990, Tim also wrote the first web page editor/browser (“WorldWideWeb.app”) and the first web page was served on the open internet.
4. The Wheel – Unknown
• The wheel was first created around 3500 BC in Mesopotamia. There is archaeological evidence of wheels dating back to at least 5500 years ago. However, nobody knows exactly who invented them. Hence, the invention of the wheel unlike other inventions cannot be credited to one inventor.
• In the time from the Neolithic to the Bronze Age, wheels crafted from wood featured a hole in the centre for the axle. Originally serving as pottery tools, they later found use in transportation and other areas.
• This invention made transportation of goods easier and boosted various sectors laying a strong foundation for several advancements in technology and engineering.

5. The Automobile – Karl Benz
• In 1885, German engineer Karl Benz, launched the first automobile.
• Karl completed the first car propelled by a petrol engine, which he named the Benz Patent-Motorwagen (World’s first automobile).
• Benz’s car had a tricycle design and used a four-stroke engine.
• This invention made travel faster and more efficient.
6. Radio – Guglielmo Marconi (Father of Radio)
• Guglielmo Marconi, an Italian inventor and electrical engineer achieved the first transatlantic radio communication in 1901.
• This invention facilitated long-distance communication and played a vital role during emergencies, aiding the military during wars and enabling news broadcasts widely.
• Today, radio, in diverse forms, continues to connect people across cultures and continents.

7. Computer – Charles Babbage
• Charles Babbage, an English mathematician, analytical philosopher and mechanical engineer, invented the first mechanical computer in the early 19th century.
• Babbage’s Analytical Engine incorporated an input device (the ability to read punch cards), a memory (storehouse), a control unit (the mill), and an output device.
• Often referred to as the ‘Father of the Computer,” his invention served as an inspiration for the modern computing era.
• It was not until the 1940s that machines like ENIAC and UNIVAC could finally realise their vision.
8. Aeroplane – The Wright Brothers
• Orville and Wilbur Wright revolutionised transportation with the successful flight of their aeroplane in 1903.
• The Wright Brothers’ biplane demonstrated the principles of aerodynamics and flight control, changing the dynamics of long-distance travel.
• The aeroplane transformed the world of transportation, making long-distance travel faster and more efficient.
9. Penicillin – Alexander Fleming
• Alexander Fleming, Professor of Bacteriology discovered Penicillin in 1928.
• This antibiotic has saved many lives by treating serious illnesses like bacterial endocarditis, meningitis, pneumonia, gonorrhoea, and syphilis.
