The Invent Blog hosts Blawg Review #146 today on National Inventor’s Day.  He also points out that the most prolific American inventor, or at least patentee, is not Thomas Edison but Illinois’s very own Donald Weder.  Mr. Weder had been granted over 1,300 patents by early November 2005, according to this USA Today story.  Most of his inventions involve flowers or items for use in flower shops.
