Born on October 16, 1758, Webster is best known for publishing An American Dictionary of the English Language, the precursor of the now famous and widely used Merriam-Webster Dictionary.
The world’s oldest dictionary was inscribed on a mud tablets 4,500 year ago in the ancient Akkadian Empire — today’s Iraq and Syria. The first English alphabetical dictionary was written by English schoolteacher Robert Cawdrey in 1604, when Shakespeare was still writing plays. (Before that, dictionaries were organized by topic, which would mean that all types of food would be listed together, for example).
