Imagine you’re running a successful fireworks company in Japan–in the 19th century. Your product is so stunning that word of it has traveled around the globe, and you’ve got would-be buyers overseas. How would you create a catalogue? With over 100 offerings in your arsenal, you need some way to show potential buyers what each firework does, but photography technology of the era won’t cut it.
What you’d have to do is hire some illustrator, then individually demonstrate for them each and every firework you produce. They would then have to sit at an easel and attempt to recreate, using paintbrushes, the light show they’d seen in that night sky. That was the path undertaken by one Ryuta Hirayama, who founded Hirayama Fireworks Mfg. in 1877 in Takashima, and patented his fireworks in the U.S. in 1883. Japan’s Yokohama City Library got their hands on an old English-language Hirayama catalogue and made the scans available online.
We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @ adafruit.com/blacklivesmatter
