The History of Brushes
The word "brush" first appeared in the English language in 1377, while the term "bottle brush" was documented in 1713. Brushes have been integral to human life for so long that pinpointing their exact origins is challenging. However, evidence suggests they were used to apply pigment as early as the Paleolithic Period, which began around 2,500,000 years ago. This is supported by the discovery of ancient cave paintings, such as those in Spain’s Cave of Altamira and France’s Périgord region. The ancient Egyptians used brushes for decorating tombs, while the Chinese employed long-haired brushes for writing.
Toothbrushes have similarly ancient origins, dating back to between 3500 and 3000 B.C., when Babylonians and Egyptians crafted brushes by fraying the ends of sticks. The first natural-bristle toothbrush is attributed to the Chinese in the fifteenth century.
In 1777, William Kent established Kent Brushes, the first company dedicated to manufacturing hairbrushes. Later, in 1854, Hugh Rock submitted the first U.S. patent for a hairbrush design. In 1898, Lyda Newman, an inventive pioneer, patented the first hairbrush with synthetic bristles. Newman also introduced brushes with detachable handles and air chambers for improved ventilation.
Early brushes, including brooms, were made using locally available materials. For instance, ancient Egyptians fashioned brushes from split palm leaves. Over time, bristle materials, primarily sourced from hogs, pigs, and boars, became popular. Advances in technology and regional resources have since expanded the variety of materials used for brush filaments.
