James Clark was the founder and the actual visionary. A lot of history has been rewritten about Marc Andreessen. Even most of the coding of the original Mosiac was done by Eric Bina.
Andreeson was also a Netscape founder. Andreeson was interesting in the web and involved in the development of a shipping web browser long before Clark got interested in the web and probably long before Clark even knew what the web was.
Clark however had money, connections and enterpreneurial and executive experience whereas Andreeson was just starting out in his career.
