Galileo (1564-1642) is credited with inventing the thermometer, but Gabriel Daniel Fahrenheit (1686-1736) invented the mercury thermometer in 1714 and used it to develope the Fahrenheit scale that is still in use today (and by Lewis & Clark).  Hope this helps.  L&C carried several scientific instruments on the Voyage of Discovery, and I think I read that more than one thermometer was carried.  Others better versed in L&C can provide more data.
