Life

Jack Dorsey grew up in St. Louis. Early on he studied road maps and listened to the police radio . According to his own statements, he started programming because he wanted to visualize what is currently happening at a certain intersection, for example. With the help of his first programming knowledge and the information from the police radio he succeeded, according to Dorsey, in “filling the virtual card with life” on the computer. He created open source programs that are used today by some taxi companies in the USA for their operational organization .

After graduating from high school, Dorsey first studied at the Missouri University of Science and Technology , a part of the University of Missouri at Rolla that is primarily geared towards engineering courses . Soon after, he moved to New York University in Manhattan . He moved to Oakland in 1999 as a programmer and went on to program guidance systems for taxis, couriers and ambulances.

Although he had the first ideas for a mobile status service at an early stage, it took a few years before they became concrete. Before starting his entrepreneurial career, Dorsey initially took various other paths. In 2000, Dorsey aspired to become a botanical draftsman, then trained as a masseur for a year and later took up a degree in fashion design. He did not complete his studies.

He worked as a mannequin.

Twitter and Square

Instead, Dorsey and his team had to go into business for themselves and look for donors who, of course, expected a corporate structure. As of 2006, Dorsey was CEO of Twitter. In 2008 he resigned from the post and was replaced by co-founder Williams, Dorsey in return took his less time-consuming job of chairman of the board .
