Over at A Synthetic Environment you can find an extensive collection of portraits of Friedrich Wohler. It’s pretty cool.  For you historians of chemistry, Wohler was a colleague of Justus von Liebig and a student of great Jons Jakob Berzelius.  After his inadvertant synthesis of urea in 1828 and subsequent realization of its significance, Wohler reportedly told Berzelius

 “I cannot, so to say, hold my chemical water and must tell you that I can make urea without thereby needing to have kidneys, or anyhow, an animal, be it human or dog“.

I do not have a primary reference for this quote, but true or not, it’s a great line.
