Back in the 1800s, information traveled slowly. Who would dream of instant messages? Samuel Morse, that's who! Who traveled to France, where the famous telegraph towers relayed 10,000 possible codes for messages depending on the signal arm positions-only if the weather was clear? Who imagined a system that would use electric pulses to instantly carry coded messages between two machines, rain or shine? Long before the first telephone, who changed communication forever? Samuel Morse, that's who!
This dynamic and substantive biography celebrates an early technology pioneer.
