Composition about Steve Jobs

Hi, can anyone correct my composition, please?

Steven Paul Jobs was born on 24th February of 1955 in San Francisco, and was adopted at birth by Paul Reinhold and Clara Jobs, five years later they moved to Mountain View in California. In 1972 Jobs graduated to the Homestead High school in Cupertino, and after trying frequenting University he decided to left it and start working on his own.
On 1st April of 1976 Jobs with two friends of his, Steve Wozniak and Ronald Wayne ,founded Apple computer in the garage of Jobs’s parents., Ronald stayed only a short time, leaving Jobs and Wozniak as the primary co-founders of the company. Their first invention was the Apple 1 computer ,which they just sold to the members of Homebrew Computer Club. After hard working and the developmenet of tecnologies, they made their most important invention, the Apple Macintosh, the first computer with graphics interface. After launching the Apple Macintosh, Wozniak decided to leave the company ,and at the same time Jobs had a row with http://it.wikipedia.org/wiki/John_Sculley, at the time the CEO of Apple company, who kicked Jobs out from his own company.
Even if he lost everything, Jobs didn’t give up, and he found another computer company, the NeXT, and bought the Pixar, today one of the most important animation studios.
At the time no one would have ever thought that jobs, being kicked out from his own company, was walking the road to a bigger success than ever. In fact, even if Jobs’ new company wasn’t as good as the old one, Apple company was on the edge of failure too, so that they called Jobs, and found an agreement, Apple company bought the NeXT, and Jobs became the new CEO, or rather the Chief executive officer.

(I'll post the second part later)
