Robert Metcalfe’s Sketch of Ethernet

1973 – Robert Metcalfe writes a thirteen-page memo describing a new type of data transmission method. His memo was entitled “Ether Acquisition”, which would connect Hawaii’s ALOHA Network.

Alto Ethernet was born on paper, but didn’t see operation until November 11, 1973 when it was implemented.

Metcalfe was awarded the IEEE Medal of Honor in 1996 for his work on inventing Ethernet. He was also inducted into the National Inventors Hall of Fame in 2007.
