Coffee addiction is pretty common these days. Many of us can’t begin a day without a hot cup of coffee. And the bitter the better, isn’t it? Melitta Bentz, a German housewife, invented the coffee machine in 1908. One day, Bentz wanted that strong kick of coffee without bitter grounds. So she designed her very own coffee machine with a filter by layering the bottom of her coffee pot with her son’s notebook paper! Yes, you read that right. Surprisingly, it actually ended up working and Melitta had her invention patented as a “Filter Top Device Lined with Filter Paper.”
10. DNA helix
Even though the discovery of the DNA double helix is attributed to Watson and Crick, who won the Nobel Prize in Physiology in 1962, it was not actually theirs to claim. Rosalind Franklin, a British biophysicist, was the first person to capture a photographic image by observing molecules using X-ray diffraction (we’ve got no idea what this is either, so don’t worry).
The big question is that why she wasn’t credited for this. Well, according to a theory, an estranged male colleague of hers showed her photograph to competitors Watson and Crick (without her permission, obviously), and the rest as they say, is his-story.
