Alexander Graham Bell

Who?

Alexander was born in 1847 Edinburgh. Alexander Graham Bell was very interested in sounds.

Why?

I don’t know why Alexander was so interested in sounds. Maybe to help deaf people to speak and help his mum hear.

How?

His dad set him a challenge to make a talking machine and it almost worked with Watson.  They rented two rooms next to each other.

What?

The mouth piece used acid to turn to electricity. Sound travels through  the wire then sound turned  back into talking.
