COUNTING THE STARS

This biography of renowned mathematician Katherine Johnson featuring illustrations by Colón aims for elementary-age readers.

Cline-Ransome (Finding Langston, 2018, etc.) traces Johnson’s love of math, curiosity about the world, and studiousness from her early entry to school through her help sending a man into space as a human computer at NASA. The text is detailed and lengthy, between one and four paragraphs of fairly small text on each spread. Many biographies of black achievers during segregation focus on society’s limits and the subject’s determination to reach beyond them. This book takes a subtler approach, mentioning segregation only once (at her new work assignment, “she ignored the stares and the COLORED GIRLS signs on the bathroom door and the segregated cafeteria”) and the glass ceiling for women twice in a factual tone as potential obstacles that did not stop Johnson. Her work is described in the context of the space race, which helps to clarify the importance of her role. Colón’s signature soft, textured illustrations evoke the time period and Johnson’s feeling of wonder about the world, expressed in the refrain, “Why? What? How?” The text moves slowly and demands a fairly high comprehension level (e.g., “it was the job of these women computers to double-check the engineers’ data, develop complex equations, and analyze the numbers”). An author’s note repeats much of the text, adding quotes from Johnson and more details about her more recent recognition.

A detail-rich picture book best for readers who enjoy nonfiction and are interested in history or science.
