Inventions that changed history, from paper to the internet
Quick answer: Some of the most important inventions are the wheel (about 3500 BC), paper (China, about 105 AD), the printing press (about 1440), the steam engine (1700s), the telephone (1876), the light bulb (1879), antibiotics (1928) and the internet (1960s–1990s).
Ancient inventions
The wheel, writing in Mesopotamia and Egypt, and paper in China made trade and records possible.
Contributions of Muslim scholars
Al-Jazari designed water clocks and mechanical devices in the 12th century, Ibn al-Haytham laid foundations of optics, and al-Khwarizmi’s work gave us the word “algorithm”.

Inventions from the Islamic Golden Age
Between roughly the 8th and 13th centuries, scholars in Baghdad, Cairo, Córdoba and other cities made major advances. Al-Khwarizmi’s work gave us the words algebra and algorithm. Ibn al-Haytham studied light and vision and is often called a father of modern optics. Al-Jazari designed water-powered machines and clocks, and Fatima al-Fihri founded al-Qarawiyyin in Fez, often cited as the oldest existing university.
Why many inventions have more than one inventor
Big inventions are rarely the work of one person. The light bulb, the telephone and the television all had several inventors working at the same time, and quizzes usually credit the person who made the first practical or commercial version.
