Apple, like much of the world, is mourning the loss of Robin Williams, and has delivered a rare public tribute on its homepage. "We are deeply saddened by the passing of Robin Williams," the company says in a message accompanying a black-and-white portrait. "He inspired us through his passion, his generosity, and the gift of laughter. He will be greatly missed."

The actor and comedian joins the likes of Rosa Parks and Nelson Mandela, two public figures to receive similar treatment. Apple co-founder and former CEO Steve Jobs was also commemorated, as was board member Jerry York.
