Steven Wozniak, co-founder of Apple Inc. and UC Berkeley alum, will be the keynote speaker at the 2013 Commencement according to an invitation to the Class of 2013 from Chancellor Robert Birgeneau.

Wozniak, who graduated in 1986 with a degree in electrical engineering and computer science, is best known as the creator of the Apple I and Apple II computers along with the late Steve Jobs. He is currently the chief scientist of Fusion-io, a data storage company.

Woz, as he is commonly called, will be speaking at California Memorial Stadium on Saturday, May 18, “rain or shine,” according to the invitation.

Since his enormous success at Apple, Wozniak has been involved in a number of philanthropic activities, especially related to education in his local community.

UC Berkeley’s Wozniak Lounge in Soda Hall bears his name.
