A pen (Latin: penna, feather) is a writing implement used to apply ink to a surface, usuallypaper, for writing or drawing. Historically, reed pens, quill pens, and dip pens were used, with a nib dipped in the ink. Ruling pens allow precise adjustment of line width, and still find a few specialized uses, but technical pens such as the Rapidograph are more commonly used. Modern types also include ballpoint, rollerball, fountain, and felt or ceramic tip pens. Ancient Egyptians had developed writing on papyrus scrolls when scribes used thin reed brushes or reed pens from the Juncus maritimus or sea rush. In his book A History of Writing, Steven Roger Fischer suggests that on the basis of finds at Saqqara, the reed pen might well have been used for writing on parchment as long ago as the First Dynasty or about 3000 BC. Reed pens continued to be used until the Middle Ages although they were slowly replaced by quills from about the 7th century. The reed pen, generally made from bamboo, is still used in some parts of Pakistan by young students and is used to write on small boards made of timber.

The quill pen was used in Qumran, Judea to write some of the Dead Sea Scrolls, which date back to around 100 BC. The scrolls were written in Hebrew dialects with bird feathers or quills. After the fall of the Roman Empire, Europeans had difficulty in obtaining reeds[citation needed] and began to use quills. There is a specific reference to quills in the writings of St. Isidore of Seville in the 7th century. Quill pens were still widely used in the 18th century, and were used to write and sign the Constitution of the United States in 1787. Quill pens were replaced some 2000 years later by the Greeks with the reed pen, made by cutting the end of the reed at an angle and making a slit opposite the cut. This proved to be nib-like and more suitable for writing the newly developed Greek alphabet.The reed pen survived until papyrus was replaced by animal skins, vellum and parchment, as a writing surface. The smoother surface of skin allowed finer, smaller writing by the quill pen, derived from the flight feather. A copper nib was found in the ruins of Pompei showing that metal nibs were used in the year 79. There is also a reference to 'a silver pen to carry ink in', in Samuel Pepys' diary for August 1663. 'New invented' metal pens are advertised in The Times in 1792. A metal pen point was patented in 1803 but the patent was not commercially exploited. A patent for the manufacture of metal pens was advertised for sale by Bryan Donkin in 1811. John Mitchell of Birmingham started to mass-produce pens with metal nibs in 1822, and thereafter the quality of steel nibs had improved enough that dip pens with metal nibs came into generalized use.

The earliest historical record of a pen employing a reservoir dates back to the 10th century. In 953, Ma'ād al-Mu'izz, the Fatimid Caliphof Egypt, demanded a pen which would not stain his hands or clothes, and was provided with a pen which held ink in a reservoir and delivered it to the nib. This pen may have been a fountain pen, but its mechanism remains unknown, and only one record mentioning it has been found. A later reservoir pen was developed in 1636. In his Deliciae Physico-Mathematicae (1636), German inventor Daniel Schwenter described a pen made from two quills. One quill served as a reservoir for ink inside the other quill. The ink was sealed inside the quill with cork. Ink was squeezed through a small hole to the writing point. In 1809, Bartholomew Folsch received a patent in England for a pen with an ink reservoir.

While a student in Paris, Romanian Petrache Poenaru invented the fountain pen, which the French Government patented in May 1827. Fountain pen patents and production then increased in the 1850s, especially steel pens produced by John Mitchell. The first patent on a ballpoint pen was issued on October 30, 1888, to John J Loud. In 1938,László Bíró, a Hungarian newspaper editor, with the help of his brother George, a chemist, began to work on designing new types of pens including one with a tiny ball in its tip that was free to turn in a socket. As the pen moved along the paper, the ball rotated, picking up ink from the ink cartridge and leaving it on the paper. Bíró filed a British patent on June 15, 1938. In 1940 the Bíró brothers and a friend, Juan Jorge Meyne, moved to Argentina fleeing Nazi Germany and on June 10, filed another patent, and formed Bíró Pens of Argentina. By the summer of 1943 the first commercial models were available. Erasable ballpoint pens were introduced byPapermate in 1979 when the Erasermate was put on the market.
