"Just attended a school his mother created in South Carolina, and he paid his way through Dartmouth College while supporting his siblings after she passed away. In muted blue hues, pencil and digital scenes by Uribe (The Queen and the First Christmas Tree) depict the undeterred scientist, surrounded by tools of his craft, teaching at Howard University and working abroad: 'Ernest worked in Europe as often and as long as he could, enjoying more warmth and respect than he'd ever felt in America.' Quotes from Just, as well as creators' notes, a timeline, and source notes, wrap up this vivid, inspiring tribute to a noteworthy life." (Publishers Weekly)

"A beautiful palette of sea blues and greens, sand and coral colors surround Just in illustrations that highlight the importance of environment and family. More than a story of triumph against the odds, this book shows the necessity of opportunity for brilliant minds to reach their potential." (Kirkus Reviews)

"This picture-book biography opens in 1911 with scientist Ernest Just collecting and studying marine worms, and then backtracks about 20 years to show him as an African American boy growing up near Charleston, South Carolina, and exploring the shore where the river met the ocean. His single mother sent him north to prep school, and after graduating from Dartmouth, he became a biology professor at Howard University and gained an international reputation through his publications on marine invertebrates and egg cells. Weary of the racial discrimination that limited his opportunities in America, he later continued his research in France and Germany. In the book's lengthy, appended notes for older readers, Mangal provides a more detailed, fascinating account of the scientist's life and work. While the main picture-book text is somewhat disjointed, it highlights experiences that children will relate to and acknowledges racial prejudice as a barrier that became intolerable to Just. The digital illustrations create distinctive period settings, while reflecting the story's sometimes lyrical tone. A picture book introducing an American scientist who should be more widely known."
