Marc Andreessen — Education: B.S. in Computer Science, University of Illinois at Urbana-Champaign

Note: The Wikipedia infobox explicitly states Marc Andreessen's education as 'University of Illinois Urbana-Champaign (BS)'. The claim specifies 'B.S. in Computer Science' but the source only confirms 'BS' without specifying the major. However, given that he is described as a 'former software engineer' and 'co-author of Mosaic,' and the context strongly supports a computer science degree, this is a minor omission in the source rather than a contradiction. The additional context about co-developing Mosaic while at NCSA is also confirmed in the source text.
