**STARRED REVIEW** This comprehensively researched and beautifully designed reference work contains profiles of over 80 scientists, mathematicians, engineers, and inventors whose work changed the world. Each profile is between 1-4 easily digested pages that cover essential information. What differentiates this work from similar ones is its scope and inclusivity. It covers history from approximately 650 BCE through the present and includes figures from Europe, Asia, the Middle East, and the modern Americas. Effort has been made to include many women, too often overlooked by historians for their contributions to science. A broad scope of scientific fields are represented: mathematics, physics, chemistry, biology, medicine, technology, geology, oceanography. All the giants are here: Archimedes, Galileo, Newton, Curie, Einstein, Turing, Goodall. Alongside them are lesser known but equally impressive people: Zhang Heng, Al-Khwarizmi, Hildegard of Bingen, António Egas Moniz, Tu Youyou. Profiles are organized based on historical era to highlight the progression of scientific thought and discovery. At the end of each section is a directory of other individuals from the era, each accompanied by a paragraph of basic information. This is an excellent resource to both browse and to serve as a launch pad for further research. Appropriate for middle school and up.

This title has been recommended for young adult readers:

YA/Curriculum Support: Easily digested, inclusive profiles of influential scientists will bolster both STEM and history coursework.
