This book explores the history of modern human creativity/innovation, highlighting examples of solutions to basic human’ needs that have been developed over time. The title – Femina Problematis Solvendis – is a play on the scientific classifications of humans (Homo habilis, Homo erectus, Homo sapiens), but with special focus on inventions pioneered by women (“femina�) and is intended to suggest that a defining characteristic of modern humans is our fundamental ability to solve problems (i.e., problem-solving woman = Femina problematis solvendis), Written by David H. Cropley, an internationally recognised expert on creativity and innovation, it also builds on his previous book “Homo Problematis Solvendis –Problem-solving Man�, published in 2019. The book explores innovations over ten distinct “ages� of human history, beginning with “prehistory�, and moving up to the present “information age�. Each era is covered by a dedicated chapter that describes three key innovations that were either definitely invented by a woman or can be plausibly attributed to a female inventor. The book focus on female inventors also serves to highlight some of the ways women have been treated in societies over time.
