1455 – Holy Type
While maybe not exactly accurate, February
23rd, 1455 is generally accepted as the date the Gutenberg Bible was
first published. This was the first book on record to be printed on movable
type. Until that point, books were copied by hand, which was obviously a slow,
laborious process.
On a side note, I challenge anyone to come up with a
historical date in technology earlier than this one! Good luck!

whom everyone called “Tootsie”. It became the first “Penny Candy” and was even
a War time ration since it could withstand severe weather conditions.
