TELEGRAPH
Samuel Morse was with friends and debating electromagnetism when he realized that if an electrical signal could travel instantly across a wire, why couldn't information do the same?
The telegraph was invented by not only Morse, but also Charles Wheatstone, Sir William Fothergill Cooke, Edward Davy, and Carl August von Steinhiel so near to each other that the British Supreme Court refused to issue one patent.
It was Joseph Henry, who discovered that coiling wire would strengthen electromagnetic induction.
Of Morse's contribution -- application of electromagnets to boost signal strength.

THE AUTOMOBILE
The car industry represents the epitome of incremental innovation. Take a tricycle. Add an engine. You've got a car. (Just look at the picture of the the original Benz Motorwagen from 1885).
Condensing the invention of cars to those six words leaves out a lot of detail and a few m...

COTTON GIN
The fabric cotton comes from cotton fibers that mix with seeds in the pods of cotton plants. To make the fabric, therefore, you have to separate the fibers from the seeds.
For centuries this was done mostly by hand, until Eli Whitney "invented" the cotton gin in 1...

Alexander Graham Bell invented a technology that would later bear his name. But how much did he deserve it?
The problem that Bell solved was to turn electrical signals into sounds.
Philip Reis had already designed a sound transmitter in 1860, and Hermann Lud...
