Jack Patrick Dorsey (born November 19, 1976)[3] is an Americansoftware developer and business person, widely known as the creator of social networking service Twitter. He is also the founder and CEO of Square, a mobile payments company.[4] In 2008, he was named as one of the top 35 innovators in the world under the age of 35.[5]
Dorsey was born Jack Patrick Dorsey in St. Louis, Missouri,[11][12] the son of Tim and Marcia (née Smith) Dorsey.[13][14][15] He is of English, Irish, and Italian descent.[16] His father worked for a company that developed mass spectrometers and his mother was a homemaker.[17]
By age fourteen, Dorsey had become interested in dispatch routing. Some of the open-source software he created in the area of dispatch logistics is still used by taxicab companies.[13] Dorsey attended the University of Missouri–Rolla for two-plus years (1995–97)[18] before transferring to New York University, but he dropped out in 1999,[24] one semester short of graduating.[18] He came up with the idea that he developed as Twitter while studying at NYU.[18][25]
Career
While working on dispatching as a programmer, Dorsey moved to California.[26][27] In 2000, Dorsey started his company in Oakland to dispatch couriers, taxis, and emergency services from the Web.[28] His other projects and ideas at this time included networks of medical devices and a "frictionless service market".[28] In July 2000, building on dispatching[13] and inspired in part by LiveJournal and by AOL Instant Messenger, he had the idea for a Web-based realtime status/short message communication service.[28]
When he first saw implementations of instant messaging, Dorsey wondered whether the software's user status output could be shared easily among friends.[13] He approached Odeo, which at the time happened to be interested in text messaging.[13] Dorsey and Biz Stone decided that SMS text suited the status-message idea, and built a prototype of Twitter in about two weeks.[13] The idea attracted many users at Odeo and investment from Evan Williams,[13] a co-founder of that firm in 2005 who had left Google after selling Pyra Labs and Blogger.
