Today is the 502nd anniversary of the birth of Conrad Gessner, regarded as the father of modern bibliography, zoology, and botany, according to Wikipedia. He was the first to catalog and describe many species in Europe, including the guinea pig, the pencil, and the tulip. In fact, most tulip cultivars today are classified as Tulipa gesneriana, named for him. He loved books, literally cutting and pasting his own database together, and reputedly requesting to be taken to his library to die amongst his tomes. The next time you see a tulip, give a little thanks to Conrad Gessner for his work.
