This may be unfair to Leibniz's work on logic, which IIRC achieved something like Boolean algebra: <a href="http://en.wikipedia.org/wiki/Gottfried_Wilhelm_Leibniz#Formal_logic" rel="nofollow">http://en.wikipedia.org/wiki/Gottfried_Wilhelm_Leibniz#Forma...</a><p>(The work went unpublished till 1903. I can't be confident this is unfair because I never finished reading the long paper reviewing it.)

It was very interesting. I first didn't realize it was Wolfram's blog. I was split by the tone of the post, which seemed to be comparing the author to Leibniz and which seemed to be a little pompous. It was an interesting bit of history about Leibniz at the end. I found the medal bit hilarious. Not quite as pompous, perhaps, a bit of harmless fun.<p>Anyhow, for math history buffs out there, if you go to Germany, drop by the Arithmeum in Bonn (<a href="http://www.arithmeum.uni-bonn.de/en/home/" rel="nofollow">http://www.arithmeum.uni-bonn.de/en/home/</a>). It is a fun place to spend an afternoon.
