Growing up in the home of a physician, Bonnie Hofkin's first picture books and early readers were medical journals and anatomy texts. With her interest in the human body thus igniting a lifelong love of art, she first obtained a BA in commercial illustration, followed by a master's degree in medical illustration. Subsequently, she embarked on a 40+ year career as a freelance illustrator. Still going strong, her unique style, in which an eye for accuracy and visual appeal is combined with a classical look reminiscent of the great Renaissance masters, is instantly recognizable.
