when was toilet paper invented in ancient china
Toilet paper Although paper had been known as a wrapping and padding material in China since the 2nd century BC,[2] the first documented use of toilet paper in human history dates back to the 6th century AD, in early medieval China.[1] In 589 AD the scholar-official Yan Zhitui (531â€“591) wrote about the use of toilet paper:
Paper clip According to the Early Office Museum, the first patent for a bent wire paper clip was awarded in the United States to Samuel B. Fay, in 1867. This clip was originally intended primarily for attaching tickets to fabric, although the patent recognized that it could be used to attach papers together.[1] Fay received U.S. patent 64,088 on April 23, 1867. Although functional and practical, Fay's design along with the 50 other designs patented prior to 1899 are not considered reminiscent of the modern paperclip design known today.[2] Another notable paper clip design was also patented in the United States by Erlman J. Wright in 1877. This clip was advertised at that time for use in fastening newspapers.[1]
