What is paper? Paper is a dried, compressed mat of plant fibers—nothing more, nothing less. It's a bit like clothing you can write on.

Clothes are made by weaving together yarns such as cotton and wool spun from natural fibers.

Paper is more like the fabric we call felt, made without the weaving stage by pressing together cellulose fibers extracted from plants and trees so they knit and fuse to form a strong, solid, but still very flexible mat.
How is paper made?
Most paper pulp is made from trees (mainly fast-growing, evergreen conifers), though it can also be made from bamboo, cotton, hemp, jute, and a wide range of other plant materials. Smooth papers used for magazines or packaging often have materials such as china clay added so they print with a more colorful, glossy finish.
Who invented paper and papermaking? 3000 BCE: Ancient Egyptians begin writing on papyrus, made from rushes growing on the banks of the Nile River. It's the first lightweight, portable writing surface. 105 CE: Chinaman Ts'ai Lun (c.50–121 CE; also written Cai Lun) invents paper based on tree bark for the Emperor of China. Papermaking technology gradually spreads throughout Asia. 1100s: The Moors introduce papermaking technology to North Africa and Spain, from where it passes to the rest of Europe. Their paper is made from hemp and linen.
1450s: German Johannes Gutenberg (c.1400–1468) invents movable metal type and the modern printing press, and prints around 180 copies of his famous Gutenberg Bible. This invention greatly increases the demand for paper. 1790s: Papermaking machines are invented by Frenchman Nicholas Louis Robert (1761–1828), then improved by British brothers Henry Fourdrinier (1766–1854) and Sealy Fourdrinier (1774–1847) around 1803. (The National Portrait Gallery has a painting of the Fourdrinier family.) 1804: Englishman Andrew Wilson produces the first book on machine-made paper. Wilson is a London-based printer employed by Charles Mahon, 3rd Earl of Stanhope, inventor of the first iron printing press (the Stanhope press). 1809: Several years after the Fourdiniers, Englishman John Dickinson (1782–1869) invents and patents an alternative papermaking apparatus called the cylinder machine. (You can see a great model of Dickinson's 1809 machine on the Science and Society Picture Library website.)
improved public hygiene. In 1931, Scott produces the first paper towels, ScottTowels, and sells them in grocery stores.
1840: The Groundwood method of making wood pulp is developed in Germany.
1883: German inventor Karl Dahl develops a chemical method for making strong paper pulp called the Kraft ("strength") process.
