 * JACK DORSEY ** **Date of Birth: Nov 19, 1976 **

**Twitter** Jack Dorsey, a software engineer, became well-known upon his and his Co-Founder's creation of the widely used social and informational network we know as Twitter. The network was created on March 21, 2006 and released to the public on July 13, 2006 after rounds of careful tweaking and perfecting. The purpose of the site is for users to be able to follow and post conversations about what they find interesting. For example, many people follow famous musicians or actors and actresses to keep up with what they're working on. The posts are called Tweets and users can make up a headlines and then attach information, pictures, and other media content on the body paragraphs of the Tweets. Users have the option of posting and contributing to the conversations or just following and reading what other people write. Either way, they stay involved and know what's happening. Twitter is based out of San Fransisco, California but is used all over the world. Because of the site's high popularity, the site now comes in multiple languages so people from all over the world can stay involved which creates a positive global impact, uniting the world. **Square** Because of the huge success of Twitter, Dorsey was inspired to invent another life changing device. He decided to call his new invention "Square". Square is a squared-shaped electronic device that attaches to IPhones, Ipads, and Andriods through the headphone jack. The device allows the user to swipe their credit or debit cards, choose the amount of money they owe to the recieving company or person, and then for confirmation purposes, sign their name. Square can also send paperless reciepts through either a text or an email. Now people are bause their checking accounts no matter where they are. **In****terestin****g I****nformation** *Dorsey became interested in computers at an early age, especially coordinating taxi drivers and delivery vans that needed to be in constant communication with one another  *At the young age of 15, he developed a dispatch software that is still used by some taxicab companies today  *He dropped out of college without a degree and started a company offering a dispatch software via the the internet  *Dorsey recieved his inspiration for Twitter while studying the aspects of instant messaging  *Dorsey and his Co-Founder built a prototype for Twitter in only two weeks time  *He was the CEO of Twitter until 2008 and is now currently serving as the chairman of the company *The three guiding principals Dorsey goes by are simplicity, constraint, and craftsmanship *Steve Jobs, founder of the Apple company, was Dorsey's inspiration for his inventions.
