Aldrovandi, Ulisse, 1522-1605, Italian naturalist, professor at the Univ. of Bologna. He instigated the establishment (1567) of the Bologna Botanical Garden and wrote an early pharmacopoeia. His chief work was the Natural History (14 vol.), of which four volumes (some sources say five) were published before his death; the rest were prepared for publication from his manuscripts.
