Today is the official birthday of Johannes Gutenberg, in Mainz, Germany. Probably around 1400, give or take some years. The city of Mainz finally chose June 24 as his big day, in the 1890s. Roughly 430 years after his death.

Mr. Gutenberg is remembered for his important contribution to literacy in the Western World, making printed material widely available via the printing press. Other than this colossal achievement, nobody knows much about him.

One thing, coincidentally, that We Rhinos know is that tonight is the Full Moon, the Strawberry Moon. Rhinos like strawberries. Also moonlight.
