Who invented the electric doorbell?
The electric doorbell was invented in 1831 by the famous scientist and inventor Joseph Henry. He had an interest in electromagnets and experimented with sending an electric current over wire to activate an electromagnet. This caused a bell to ring and, with this, the idea for a modern doorbell was conceived.
Joseph Henry’s ideas and experiments led to many other inventions, including the telegraph, electric motor and telephone. In fact, the inventor of the telephone, Alexander Graham Bell, said that his invention couldn’t have happened without the work done by Joseph Henry.
