Steve Jobs has died at the age of 56 just a couple of months after he stepped down from running Apple.
The former CEO of the Mac maker had been struggling with health problems for the last few years, first revealing he had cancer back in 2004.
But despite attempts by doctors to fight the disease he had to take more time off and in his few public appearances in the last year he appeared to be thin and still unwell.
