Charles Alexandre Lesueur was a French naturalist, artist, and explorer. He was a prolific natural-history collector, gathering many type specimens in Australia, Southeast Asia, and North America, and was also responsible for describing numerous species, including the spiny softshell turtle, smooth softshell turtle, and common map turtle. Both Mount Lesueur and Lesueur National Park in Western Australia are named in his honor.

Johann Carl Bodmer was a Swiss-French printmaker, etcher, lithographer, zinc engraver, draughtsman, painter, illustrator, and hunter. Known as Karl Bodmer in literature and paintings, his name was recorded as Johann Karl Bodmer and Jean-Charles Bodmer, respectively. After 1843, likely as a result of the birth of his son Charles-Henry Barbizon, he began to sign his works K Bodmer.
