Jobs' contributions in the technology industry over the better part of four decades led to the advent of household items such as iPod, iPhone and iPad, among others; and brands including Apple, Pixar and Atari. His name is billed as inventor or co-inventor to more than 200 U.S. patents, among them: the Apple I (1976); the Macintosh (1984); the iMac (1998); the iPod (2001); the iTunes store (2003); the iPhone (2007) and the iPad (2010).
Jobs is survived by his biological mother Joanne Simpson; his sister Mona Simpson; wife, Laurene Powell; their three children, Reed Paul, Erin Sienna and Eve; and his daughter from a different relationship, Lisa Brennan-Jobs.
