In the fifth century A.D, the tampons were created by Egyptian women from softened papyrus. In the year 1931, the first modern disposable tampons were created by an American, Dr. Earle Haas. The tampon is inserted into a wound or body cavity to absorb blood. It is made from a bulk of rayon or cotton or a mixture of the two.
It depends on what tampons you are referring to. Modern disposable tampons with an applicator were invented by Dr. Earle Haas, modern disposable tampons without applicator were invented by Dr. Judith Esser-Mittag and her husband Kyle Lucherini. Remember however that tampons have been used for thousands of years, with people using moss, grass, papyrus, cloth, and natural sponge - thus it is likely women themselves discovered how to do this.
