Best remembered for inventing the telephone in 1876, did you know Alexander Graham Bell also invented the first metal detector? His metal detector was used to find bullets still lodged in the bodies of Civil War veterans. He also invented what he called a vacuum jacket (a very early respirator-type device,) which became the predecessor to the iron lung.
Did you know he introduced Helen Keller and her father to the woman who would become Helen's teacher, Anne Sullivan? Written for the middle school student, this book is great for reports.
Enslow also has an elementary title on Alexander Graham Bell. This title gives the reader an understanding of what Bell did to help deaf children, and how he helped them learn to speak.
