An inventor is a person who creates or develops, the original product, process, or method. Often an inventor obtains a patent for their new "intellectual property" to prevent other people from copying it to sell as their own.
In the computer world, there have been many great inventors who have helped shape the industry. Doug Engelbart invented the first computer mouse. Steve Wozniak helped invent and develop the first Apple computer. Hedy Lamarr helped to invent the spread-spectrum technology, used in many applications today. Grace Hopper helped to invent some of the earliest programming languages, including COBOL.
