Two Internet pioneers, Jim Clark of Netscape and David Filo of Yahoo, are donating $30 million each to Tulane University, where they studied during their undergraduate years.

In announcing the donations Thursday, the New Orleans university said the contributions represent the largest contributions ever received in the school's history. Tulane said income from the donations would be used to aid students who show "extraordinary academic talent."

"Wonderful things happen when a great idea is given the capital support it needs," said Clark in a statement. Clark co-founded Web-browser pathfinder Netscape, and, later, the Healtheon/WebMD virtual health-care network. Earlier, he founded Silicon Graphics Inc.

Louisiana native David Filo received his bachelor's degree in computer engineering from Tulane and went on to study at Stanford University. He received a master's degree in electrical engineering from Stanford. At Yahoo, he directs technical operations.
