An early bootstrapping publisher who, it seems, invented the periodical magazine format for distributing information. . From Wikipedia ...
The son of a cobbler, Cave was born in Newton near Rugby, Warwickshire and attended the grammar school there, but was expelled after being accused of stealing from the headmaster. He worked at a variety of jobs, including timber merchant, reporter and printer. He conceived the idea of a periodical that would cover every topic the educated public was interested in, from commerce to poetry, and tried to convince several London printers and booksellers to take up the idea. When no one showed any interest, Cave took on the task by himself. The Gentleman's Magazine was launched in 1731 and soon became the most influential and most imitated periodical of its time. It also made Cave wealthy.
Some info on The Gentleman's Magazine:
The Gentleman's Magazine was founded in London, England, by Edward Cave in January, 1731. The original complete title was The Gentleman's Magazine: or, Trader's monthly intelligencer. Cave's innovation was to create a monthly digest of news and commentary on any topic the educated public might be interested in, from commodity prices to Latin poetry. It carried original content from a stable of regular contributors, as well as extensive quotes and extracts from other periodicals and books. Cave, who edited The Gentleman's Magazine under the pen name "Sylvanus Urban", was the first to use the term "magazine" (meaning "storehouse") for a periodical. The iconic illustration of St John's Gate on the front of each issue (occasionally updated over the years) depicted Cave's home, in effect, the magazine's 'office'.
Cave also had an eye for talent: he hired the young Samuel Johnson as a writer after Johnson had to drop out of Oxford (for lack of money).
