"A must-purchase picture book biography of a figure sure to inspire awe and admiration among readers."—School Library Journal (starred review)
Extraordinary illustrations and lyrical text present pioneering African American scientist Ernest Everett Just.

Ernest Everett Just was not like other scientists of his time. He saw the whole, where others saw only parts. He noticed details others failed to see. He persisted in his research despite the discrimination and limitations imposed on him as an African American. His keen observations of sea creatures revealed new insights about egg cells and the origins of life.
Through stunning illustrations and lyrical prose, this picture book presents the life and accomplishments of this long overlooked scientific pioneer.
