Melitta Bentz of Dresden, Germany, invented the first coffee filter because she didn't want over brewed coffee. After trying different materials, she found that her son's blotter paper worked best. That was in June, 1908, and the coffee filter and coffee filter paper was patented. In December, 1908, Mellita and her husband Hugo started the Melitta Bentz Company. The Melitta Company is now world wide with great products. Bearwiskers thanks Melitta for a great invention!
