Paper from a notebookSourced
Her son’s blotting paper became a coffee filter
Melitta Bentz experimented with blotting paper from her son’s notebook in a perforated container to improve coffee brewing. In 1908 she received a patent for her paper filter. A material already in the household found a new role in preparing a morning drink.
The notebook supplied more than a surface for writing.
