This Sunday will be Steve Jobs Day in the State of California, Gov. Jerry Brown tweeted Friday night. The same day, Apple Inc. will conduct an invitation-only memorial service for its late co-founder and former CEO at Stanford University.

Earlier, it had been reported Apple would hold a memorial service for Jobs on Oct 19. According to a memo sent by CEO Tim Cook, this event for employees is to be held at an amphitheater on the company's Cupertino campus. Cook's memo read, in part: Like many of you, I have experienced the saddest days of my lifetime and shed many tears during the past week. And I've found comfort in both telling and listening to stories about Steve.

Jobs was diagnosed with a rare form of pancreatic cancer in 2003. He died Oct. 5 at the age of 56. Jobs' capacity to recognize the potential of both his products and the people around him significantly affected the conduct and performance of the organization. Jobs was famous for focusing on Apple's strategic choices and demonstrating the practicality of each, even when they were difficult to achieve.

Meanwhile, Jobs' authorized biography Steve Jobs, written by Walter Isaacson, former chairman of CNN and former managing editor of Time magazine, is scheduled for release on Oct. 24. The book's publisher, Simon & Schuster, said the book is based on more than 40 interviews, spread over two years, with Jobs, as well as interviews with more than 100 people, including family members, friends, adversaries, competitors, and colleagues.
