The private memorial for Steve Jobs, legendary tech visionary and creative genius who passed away on Oct. 5, will be held in Stanford University on Sunday evening.

Apple has already sent out the invitations for Silicon Valley's biggest names, to those who are Silicon Valley luminaries and others close to Jobs, the invitees told WSJ.

According to an Apple spokesman, the memorial is private and invitation-only service.

The guests were asked to respond to Emerson Collective, a philanthropic organization established by Jobs' wife Laurene Powell Jobs.

Moreover, this Sunday will also be announced as Steve Jobs Day to honor the great innovator. California Governor Jerry Brown tweeted on Friday evening to declare that Oct. 16 will be Steve Jobs Day in the State of California.

Besides the private memorial, Apple will also host an event for its employees to pay tribute to Jobs in Apple headquarters Cupertino, Calif. on Oct. 19.

It is not very surprising that so many people paid tribute to Jobs as he had created the Apple empire and had radically changed the way people used technology in their daily lives.

As the current CEO Tim Cook said, “Apple has lost a visionary and creative genius, and the world has lost an amazing human being.”

“The world rarely sees someone who has had the profound impact Steve has had, the effects of which will be felt for many generations to come, Bill Gates, Microsoft Co-Founder and Chairman, said in his tribute to Jobs.
