In 1806 – Englishman Ralph Wedgwood received the first patent on carbon paper, which led to the initials cc to indicate a carbon copy which led to the email option to “cc” somebody.

In 1954 – IBM sounded the death knell of vacuum tubes, building the first calculating machine to use solid-state transistors.
