Apple CEO Tim Cook remembering Steve Jobs on the fourth anniversary of his deathReuters

Four years ago the tech world lost Steve Jobs, iconic leader and the man behind the world's most valuable company Apple. Although Hollywood is set to pay homage by releasing the Steve Jobs movie on 9 October, and the recently released documentary Steve Jobs: The Man In The Machine already tried to portray his image on a cinema screen, CEO Tim Cook used his own ways to honour Jobs on the fourth anniversary of his death.

As reported by The Telegraph, Cook, in an internal email sent to Apple staff, urged his staff members to stop each other to "ask what he was really like".

"Steve was a brilliant person, and his priorities were very simple. He loved his family above all, he loved Apple, and he loved the people with whom he worked so closely and achieved so much," he wrote. "Each year since his passing, I have reminded everyone in the Apple community that we share the privilege and responsibility of continuing the work Steve loved so much." Cook further notes that Jobs' legacy is available all around the company, from an "incredible team" to "soaring achievements in technology and architecture".

"He told me several times in his final years that he hoped to live long enough to see some of the milestones in his children's lives. I was in his office over the summer with Laurene and their youngest daughter. Messages and drawings from his kids to their father are still there on Steve's whiteboard," he continued.

Jobs was born on 24 February 1955, and had co-founded Apple together with Steve Wozniak in 1976. Under his leadership, Apple brought the first iPhone in 2007 and the first iPad in 2010. He died of complications related to pancreatic cancer aged 56 in October 2011.

In a separate essay, which was first published on BuzzFeed, Cook revealed that he was willing to donate a portion of his liver to Jobs. "I was worried he would not live long enough to reach the top of the waiting list for a cadaver liver. After checking out my own health and researching donor liver transplants, I visited Steve again and told him I wanted to give him a portion of my liver", he wrote. "Despite his condition and the uncertainty of whether he would live long enough to be at the top of the waiting list, he adamantly refused to accept my offer for fear it would place my own health in jeopardy."

Apart from his leading position at the Cupertino company, Jobs was the CEO and largest shareholder of Pixar Animation Studios and was the board member of The Walt Disney Company. He was named the most powerful person in business by Fortune magazine and was one of the top innovators and business leaders in the US.
