||1856: William Henry Perkin, an English chemist, applied for a British patent titled "Dyeing Fabrics" for his invention of aniline dye "producing a new coloring matter for dyeing with a lilac or purple color stuffs of silk, cotton, wool or other materials." It was sealed on 20 Feb 1857. This was the first synthetic dye, which he obtained at first unintentionally from coal tar (a by-product of coal gas production) while seeking a method to prepare the anti-malarial drug quinine from that source. Perkin was just 18 years old. With help from his father and brother, he began manufacturing the dye, which he called Tyrian purple. Within a few years, he was wealthy and in in 1873 sold the business to turn to chemistry full-time.

||1883: Mount Krakatoa, an island volcano in the Dutch Indies (now Indonesia) erupted with violent explosions that destroyed two thirds of the island. It produced huge tsunami waves that swept across the immediate region, killing an estimated 36,000 people. These waves were powerful enough to cross the Indian Ocean and travel beyond Cape Horn. The most powerful blast was the most violent known in human history—it  was loud enough to be heard in Australia. The shockwave was registered by barometers England. The huge amount of volcanic dust thrust high into the stratosphere eventually travelled around the world. The dust blocked sunlight causing temperature drops, highly coloured sunsets, and chaotic weather patterns for several years afterwards.
