亚历山大·格雷厄姆·贝尔,电气工程学家、发明家、企业家和聋哑教育家,出身于苏格兰,1870年移民加拿大,而后移居美国,在波士顿大学工作。贝尔的父亲从事聋哑人教育工作。受父亲的影响,贝尔从小就对语言和声音传播很有兴趣。在一次做电报实验时,他发现一块铁片在磁铁前面振动发出的微弱声响竟通过导线传到了远处。这个现象给了贝尔很大的启示。1875年贝尔发明了电话,随后经过不断实验、改进,终于在1876年3月通过他发明的装置传出了人类在电话机上说的第一句话。为此他申请并获得了世界上第一台可用电话机的专利权,而后他创建了贝尔电话公司(AT&T公司的前身)。除此之外,贝尔还制造了助听器,改进了爱迪生发明的留声机,设计出一个检验人体内金属的装置,成为X光机的前身。在教育及社会工作方面,贝尔继承父业,致力于聋哑教育,对聋哑语的发明贡献甚大,他写的文章和小册子超过100篇(本)。他还是美国“国家地理学会”(Natinal Gegraphic Sciety)和《科学》(Science)杂志的创办人。
