内容简介

Alexander Graham Bell's life as inventor, scientist, and teacher is clearly told in a question-and-answer format, and complemented by a mix of photographs and illustrations. We learn not only how the telephone was invented and the mechanics behind its use, but how Bell's personal history, such as his mother being deaf, led to his interest in discovering alternate modes of communication.
