Biographical/Historical note
James A. Jensen (1918-1998) was a paleontologist and Director of the Earth Sciences Museum at Brigham Young University (BYU). While at BYU, he conducted fieldwork in both North and South America, at which point he may have met Vladimir Kozak. He created pastel and acrylic artwork, particularly of flowers, landscapes, and Native Americans.
Artist Vladimir Kozak was trained in Czechoslovakia in mechanical engineering, sculpture, and painting. In 1923, he immigrated to Brazil. As Kozak's interest in the Indigenous tribes of Brazil grew, he increasingly focused on painting and sculpting, particularly during the 1940s and 1950s. He also became a still photographer, film maker, and collector of Indigenous artifacts.
