Leonard M. Greene has patented more than 100 inventions, including the stall-prevention device which is part of the safety equipment of all aircraft. In this text, he asserts that ＂necessity is
not the mother of invention; imagination is.＂ He presents examples designed to encourage imagination and the quality of ＂inventorship＂ which he considers innate to all people. Greene further
asserts that inventorship is helpful not only for inventing new technology, but for solving everyday problems. The text does not provide instructions for registering patents or other technical
information, and does not include bibliographical references. Annotation c. Book News, Inc., Portland, OR (booknews.com)
