Tsai Lun, is the inventor of paper. He lived and served as an official at the Chinese Imperial Court at the Han Dynasty in China at about 1800 years ago. In or about the year 105 A.D., He took the inner bark of a mulberry tree and bamboo fibers, mixed them with water, and pounded them with a wooden tool. He then poured this mixture onto a flat piece of coarsely woven cloth and let the water drain through, leaving only the fibers on the cloth. Once dry, Ts'ai Lun discovered that he had created a quality writing surface that was relatively easy to make and lightweight. He presented Emperor Han Ho Ti with samples of the paper. Chinese records do mention and credit Tsai Lun with the invention of paper. His name is well known in China.

Tsai Lun was a eunuch. Because he was an officer, he had the access to lots of resources, including money and human resources, for papermaking research. He was promoted by the Emperor for his invention and became wealthy. Later he got involved in palace intrigue, which led to his downfall. Finally he ended his life drinking poison.

Even though archaeological evidence shows that paper may have been made even a little earlier, Ts'ai Lun was the first to have his efforts recorded. Like many inventors through the centuries, he built upon the work of others.

Okay, people had written even before paper was invented. They scratched on cave walls, painted too, and drew characters on wet clay. They even wrote on papyrus made from thinly-sliced papyrus reed which they glued together to make a sheet.

But it was paper, not papyrus, which has come to touch just about every aspect of our lives, from term papers and books, to money and personal care products.

Of all the writing and drawing materials that people have employed down the ages, paper is the most widely used around the world. Its name derives from papyrus the material used by the ancient Egyptians, Greeks and Romans. Papyrus, however, is only one of the predecessors of paper that together are known by the generic term ‘tapa’ and are mostly made from the inner bark of paper mulberry, fig and daphne.

Tapa has been found extensively in nearly all cultures along the Equatorial belt and is made by what is possibly the oldest papermaking technique – one still practised in some parts of the Himalayas and South East Asia. Indeed, recent archaeological excavations in China have revealed some of the oldest ‘tapa’ paper ever found which shows that paper was being produced in China before western records began. [c.3000BC]

The tapa technique involves cooked bast, which is flattened with a wooden hammer to form a thin, fibrous layer and then dissolved in a vat with water to make a pulp. A screen consisting of a wooden frame with a fabric base is then laid in a puddle or big basin and floats with the fabric just under the surface of the water. The papermaker then pours the quantity of pulp needed to make one sheet into this ‘floating mould’ and spreads it evenly, by hand, across the surface. The screen is then carefully lifted out of the water, allowed to drain off and a sheet of paper forms on the wire. Once the water has dripped off, the screen is placed in the sun or near a fire to dry. When dry, the sheet easily peels off and, apart from possible smoothing, requires no further treatment. This technique has two basic drawbacks. Firstly, a separate screen is needed for each new sheet, and is only available for use again after the last sheet has dried. And secondly, an increase in production can soon lead to a shortage of raw material, since fresh bast is not always available everywhere in the required quantity.

The fibres normally used for textiles, like flax and hemp, also served as substitutes for bast. In later times, the fabric was replaced by fine bamboo sticks, which freed the papermaker of the need to let the paper dry naturally in the mould, since the poured or ladled sheet could be ‘couched’ off.

There was never a particular year that it was invented , some cultures used thin sheets of papyrus, some silks. But most used vellum, which was lamb skin. And these thing where notable used before 650 b.c. Paper evolved. Weird to remember things like that................

They say that paper was invented in China. In fact, they say that paper was invented in the year 105 by a man called Cai Lun. He lived in Shaanxi province during the Han dynasty almost 1900 years ago.

What Year Was Paper Invented

The word paper comes from the ancient Egyptian writing material called papyrus, which was woven from papyrus plants. Papyrus was produced as early as 3000 BCE in Egypt, and in ancient Greece and Rome. Further north, parchment or vellum, made of processed sheepskin or calfskin, replaced papyrus, as the papyrus plant requires subtropical conditions to grow. In China, documents were ordinarily written on bamboo, making them very heavy and awkward to transport. Silk was sometimes used, but was normally too expensive to consider. Indeed, most of the above materials were rare and costly.

The Chinese court official Cai Lun (蔡倫) described the modern method of papermaking in AD 105; he was the first person to describe how to make paper from wood pulp. Archeologically, true paper had been excavated in China dated from the 2nd-century BC. It spread slowly outside of China; other East Asian cultures, even after seeing paper, could not figure out how to make it themselves. Instruction in the manufacturing process was required, and the Chinese were reluctant to share their secrets. The technology was first transferred to Korea in 604 and then imported to Japan by a Buddhist priest, Dam Jing (曇徴) from Goguryeo, around 610, where fibres (called bast) from the mulberry tree were used. After further commercial trading and the defeat of the Chinese in the Battle of Talas, the invention spread to the Middle East, where it was adopted in India and subsequently in Italy in about the 13th century. They used hemp and linen rags as a source of fiber. The oldest known paper document in the West is the Missel of Silos from the 11th century.

Some historians speculate that paper was the key element in global cultural advancement. According to this theory, Chinese culture was less developed than the West in ancient times prior to the Han Dynasty because bamboo, while abundant, was a clumsier writing material than papyrus; Chinese culture advanced during the Han Dynasty and preceding centuries due to the invention of paper; and Europe advanced during the Renaissance due to the introduction of paper and the printing press.

Paper remained a luxury item through the centuries, until the advent of steam-driven paper making machines in the 19th century, which could make paper with fibres from wood pulp. Although older machines predated it, the Fourdrinier paper making machine became the basis for most modern papermaking. Together with the invention of the practical fountain pen and the mass produced pencil of the same period, and in conjunction with the advent of the steam driven rotary printing press, wood based paper caused a major transformation of the 19th century economy and society in industrialized countries. Before this era a book or a newspaper was a rare luxury object and illiteracy was normal. With the gradual introduction of cheap paper, schoolbooks, fiction, non-fiction, and newspapers became slowly available to nearly all the members of an industrial society. Cheap wood based paper also meant that keeping personal diaries or writing letters ceased to be reserved to a privileged few. The office worker or the white-collar worker was slowly born of this transformation, which can be considered as a part of the industrial revolution.

Unfortunately, the original wood-based paper was more acidic and more prone to disintegrate over time, through processes known as slow fires. Documents written on more expensive rag paper were more stable. The majority of modern book publishers now use acid-free paper.

Don't know for sure, but it was developed by the Egyptians several thousand years ago
