Since a very young age, Robert E. Bear has been interested in wildlife and nature, in what could be a case of nominative determinism, which theorizes that one's name can have an impact on their career, personality, or character. This was further reinforced by his experience exploring the woods and rivers with his cousins, who are of Native American descent, at the Lower Sioux Indian Community in Minnesota. At the age of 12, Bear took up painting, primarily focusing on wildlife, as a way to immortalize the beautiful creatures he saw.
Bear also credits his father, who was a silhouette artist, for awakening his interest in art and becoming his first art teacher. Despite his father tragically dying when Bear was eight years old, his interest in art never waned.
