First Adding Machine
The first adding machine was created by Wilhelm Schickard, thus aiding with the future use and development of Mathematics. -
Pascal's Calculator
Blaise Pascal creates the first mechanical calculator capable of adding whole numbers containing up to six digits. Inspired Gottfried Leibniz to construct a more sophisticated calculator that could add, subtract, multiply, and divide whole numbers. Both were unreliable and did not enjoy commercial success, but inspired more inventors in the future. -
The Arithmometer
Charles Thomas de Colmar creates the Arithmometer, the first commercially successful calculator. It reduced the amount of time required to do math operations and allowed others to use this design for further improvements in the future. -
First Computer
Charles Babbage creates the first steam-driven calculating machine to computer numbers (a.k.a. the first computer). This machine became the first stepping stone for the future creation of computers. -
The Telegraph
Samuel Morse creates the telegraph to allow for long distance communication. The telegraph system wasn't fully used until 1843 when Congress appropriated $30,000 to Morse for the construction of a 40-mile telegraph line between Washington, DC, and Baltimore, Maryland. This began to allow long distance communication around the nation. -
The Telephone
Alexander Graham Bell and Thomas A. Watson create the first telephone. Allowed for citizens and businesses to communicate more easily over long distances. This also allowed business to be conducted from home or in one's privacy. -
Internet
Robert Kahn and Vinton Cerf create the TCP/IP protocol to divide a message into packets at the sending computer and reassembling the packets at the receiving computer. This was the date that all ARPANET hosts converted to TCP/IP (the birth of the Internet). -
