Katherine Johnson was 97 years old in 2015, when the world caught up to her. That year, President Barack Obama awarded her the prestigious Presidential Medal of Freedom-the nation's highest civilian honor-for her pioneering work decades earlier as a mathematician on NASA's first flights into space. The next year, a blockbuster movie, Hidden Figures, told the world the story of the West Area Computing unit, where Katherine worked as a human computer among an unheralded cadre of African American female mathematicians. In the days before IBM introduced its first electronic computers and at a time when African Americans were subjected to inferior treatment and status, these brilliant women were among those doing the computations that helped send the United States' first manned spaceflights to the moon. Even among such a talented group, Katherine stood out. Astronaut John Glenn was reluctant to trust her computations of NASA's first electronic computers for the trajectory of his 1962 flight to the moon, until Katherine did the math by hand. "Get the girl," Glenn said then, referring to Katherine. "If she says they're good, then I'm ready to go." Now, in her definitive new memoir, Katherine shares her personal journey from a child prodigy growing up in the Allegheny Mountains of West Virginia to the peaceful centenarian she was in her final days. In A Remarkable Journey: The Wisdom, Grit, and Grace of a Pioneering NASA Mathematician, Katherine wraps her story around some of the basic tenets of her life-the value of knowing that no one is better than you, education is paramount, timing is everything, and asking questions can break barriers. Readers will see this heroine in full dimension-curious "daddy's girl," standout college student, pioneering professional, doting mother, grieving widow, and sage elder. They will hear the wisdom of a woman who handled great fame with genuine humility and great tragedy with enduring hope. They will see the brilliance of a young college student who latched onto a dream, inspired by a college professor who told her she would make a good "research mathematician." She would carry the mantle of that professor, who in 1933 became one of the first African Americans in the country to receive a doctorate in math, only to find his own dreams of becoming a research mathematician crushed by racism. The book moves with Katherine through 100 years of racial history, pausing to show, for example, the influential role that educators at segregated schools and Historically Black Colleges and Universities played in nurturing the dreams of trailblazers. In this uplifting narrative, readers see a woman who navigated tough racial terrain with the soft-spoken grace expected of a woman of her era, and the unrelenting grit required to make history and inspire future generations.
