WITH OUT THE PHONE,
Just about every war after 1876 would have been
lost
We would have telegraph booths instead of phone
booths
We wouldn’t have cell phones, pagers, fax
machines, or iPhones
Texting would be Morse code, sent from a
telegraph in your house, to another one in your
friends.

Hydrofoils- Struts on boats that make them faster

from diabetes, leaving a huge controversy behind.
Who takes credit for the telephone, Canada, or the
US?

continued to this very day. Any new cellphone,
iPhone, or change to the Bell telephone company, is
directly effecting something Alexander worked on,
over 100 years ago. So, next time you’re texting your
