亞歷山大·格雷厄姆·貝爾，電氣工程學(xué)家、發(fā)明家、企業(yè)家和聾啞教育家，出身于蘇格蘭，1870年移民加拿大，而后移居米國，在波士頓大學(xué)工作。

貝爾的父親從事聾啞人教育工作。受父親的影響，貝爾從小就對(duì)語言和聲音傳播很有興趣。在一次做電報(bào)實(shí)驗(yàn)時(shí)，他發(fā)現(xiàn)一塊鐵片在磁鐵前面振動(dòng)發(fā)出的微弱聲響竟通過導(dǎo)線傳到了遠(yuǎn)處。這個(gè)現(xiàn)象給了貝爾很大的啟示。

Let’sknowmoreabouthim!

1875年貝爾發(fā)明了電話，隨后經(jīng)過不斷實(shí)驗(yàn)、改進(jìn)，終于在1876年3月通過他發(fā)明的裝置傳出了人類在電話機(jī)上說的第一句話。為此他申請(qǐng)并獲得了世界上第一臺(tái)可用電話機(jī)的專利權(quán)，而后他創(chuàng)建了貝爾電話公司（AT&T公司的前身）。
