His mother was deaf,his father was a teacher who taught
the deaf to speak.Aleck made an iron breathing lung.
His inventions,wax records and a fast hydrofoil, were the strongest inventions in America at that time.
In 1876,at the age of ,29, Alexander invented his telephone
Among one of his first innovations after the telephone was the ,Photophone,adevice that enabled sound to be transmitted on a beam of light. By the 1890, Bell had begun experimenting with propellers and kites.Bell also worked on methodes of removing salt from seawater.
