An illustrated biographical survey of 76 inventors and technologists including brief, simple introductions to their innovations. Included in the compendium are well known inventors such as Alexander Graham Bell and Thomas Edison, but Karwatka (industrial education, Morehead State U.) has also selected notable but less recognized men and women such as John Hyatt (plastic) and Nikola Tesla (ac electricity). The biographies emphasize the individuals' creativity and persistence, making the volume a particularly suitable modern technology introduction for younger students.
