Steve Jobs (February 24, 1955 – October 5, 2011) was an American entrepreneur and business magnate. He was the chairman, chief executive officer, and a co-founder of Apple Inc.
Apple merged with NeXT in 1997, and Jobs became CEO of his former company within a few months. He was largely responsible for helping revive Apple, which had been at the verge of bankruptcy. He worked closely with designer Jony Ive to develop a line of products that had larger cultural ramifications, beginning in 1997 with the "Think different" advertising campaign and leading to the iMac, iTunes, iTunes Store, Apple Store, iPod, iPhone, App Store, and the iPad. In 2001, the original Mac OS was replaced with a completely new Mac OS X, based on NeXT's NeXTSTEP platform, giving the OS a modern Unix-based foundation for the first time.
For me he has made devices most can't do without, similar to a nut for a squirrel.
