As a boy, Vivien Thomas dreamed of becoming a doctor, even though Black doctors were rare in his community. . . . After accepting a position as assistant to Dr. Wilfred Blalock, head of the surgical research laboratory at the Vanderbilt University School of Medicine, Thomas patiently shared his knowledge with medical students. Later, he followed Dr. Blalock to Johns Hopkins, where they worked to develop a surgical technique to save the lives of children with “blue baby syndrome." Schoettler approaches her subject with admiration and offers several examples of the roadblocks that prevented him from fully achieving his dream of attending medical school. This attractive picture-book biography encourages students to aim high, work hard, and keep moving toward their goals. Illustrated with handsome scenes reflecting Thomas' era, Schoettler's engaging narrative emphasizes his devotion to his dream of becoming a doctor and the great respect he earned from others along the way.

A tribute to a pioneering African American cardiac surgeon. Growing up in the South as the sort of person who “loved solving problems and figuring things out,” Vivien Thomas never enrolled in college but worked his way up as a white medical researcher’s lab assistant to become an expert on the malady known as “blue baby syndrome.” Breaking the color bar, he joined a team of white surgeons at Johns Hopkins that in 1944 used techniques that Thomas developed on dogs to perform the first successful open-heart surgery on a child. Thomas then went on to perform and teach the procedure there for many years while, Schoettler points out, being so underpaid that he had to tend bar and work other jobs to make ends meet. He was not, she goes on pointedly, even awarded a doctoral degree until 1976, when he was 65 years old, or given proper credit in the procedure’s formal name until 2023. Still, the author tells his story in positive tones overall, reserving further specifics about the discrimination he faced to her afterword. Walthall’s illustrations add helpful details of the surgery to views of the sober Thomas hard at work, later surrounded by increasingly diverse groups of his patients and students. A sympathetic profile of an achiever well worth knowing better.
