The man who made his name with urine.
Man has always been attracted to gold, it's bright yellow colour and easy ductility made it for one a perfect material for jewellery. This attraction brought forward an intense search for the synthesis of gold from other metals, a search conducted by alchemists all over time and place.
In 1669 an alchemist in Hamburg, Hennig Brand, thought he had find the answer: gather urine and let it stand for days until the air is filled with a terrible smell, subsequently boil it down to a paste, heat this paste to a high temperature and gather the vapours through water were gold finally will form as an end product. Much to his surprise, no gold was to be found... nevertheless, the experiment wasn't a complete failure. A waxy white substance that glowed in the dark had formed which he named 'phosphorus', the Greek word for light-bearer. He had just discovered a new chemical element, and had by this immortalized his name in history.

Good single focus and flow. Too many accuracy errors for such a short text. As for flow, try to keep the wording simple. ODP
