Growing up in a house full of brothers and sisters, persistence and a passion for problem solving became the cornerstone for a career as an engineer and his work with NASA. But it is his invention of the Super Soaker water gun that has made his most memorable splash with kids and adults.

This encyclopedia provides the most complete treatment to date of the accomplishments of African American scientists—and the struggles of African Americans to find their place in the scientific community. This comprehensive reference work sheds new light on an aspect of African American life that is often overlooked. More than a summary of individuals and accomplishments, African Americans in Science: An Encyclopedia of People and Progress explores the entire experience of African Americans seeking a place in the scientific community—not just the triumphs but the frustrations, discriminations, and the efforts to support (and sometimes impede) African American scientists. African Americans in Science offers alphabetically organized entries in three areas: the contributions of African Americans in over 30 different fields of science and medicine, schools and organizations that played a role in the development of African American scientists, and additional topics related to African American scientists. No other reference offers such a complete and up-to-date portrait of the pivotal work of African Americans across the spectrum of scientific research and what it took to achieve it.

Memoir of the life of Dr. Gladys B. West, a black woman who played an integral role in the development of the GPS.

As a kid, Lonnie Johnson liked to invent things. He often faced prejudice as an African American growing up in the segregated southern United States, but he eventually became an engineer for the US Air Force and NASA. He was working on a different invention when he came up with the idea for a new type of water gun. Johnson knew his toy was more powerful than other squirt guns—he just needed to find a way to make the Super Soaker available to kids all over the country. Learn how Johnson overcame many challenges to become a brilliant engineer and inventor.
