Alfred Byrd Graf (November 23, 1901 – December 14, 2001) was a German-American botanist who traveled the world in search of obscure plant species, discovering more than 100 previously undocumented varieties. He photographed and documented his findings in a number of richly illustrated (and correspondingly expensive) books he wrote on the subject. Graf was born in Nuremberg on November 23, 1901 and studied at botanic gardens in Vienna and took courses in botany, photography and language throughout Europe, in California and at Fairleigh Dickinson University.
