We owe the coffee filter to the German inventor and entrepreneur Melitta Bentz who developed this invention in 1908 . At the beginning of the 20th century, the usual method of making coffee was to tie the grounds in a small cloth bag and place the bag in a pot of boiling water; the result was a bitter and gritty drink. Bentz devised a new method using a piece of thick absorbent paper in a brass pot with some holes punched out; He poured the coffee through this two-part contraption, which trapped the grounds and allowed the liquid to seep and drip into a cup.
Her grandchildren still continue to run the company that Melitta Bentz founded.
There are many other inventions created by women. This is just an example, but we could also cite other female inventions such as non-reflective glass, the first security system, GPS, COBOL language, ice cream maker, aquarium, portable X-ray, paper bag with flat bottom, tipp-ex, fiber optic cable, VoIP technology (voice over ip) or the first laser surgical device.
