Intel Corp. co-founder Gordon Moore has donated $12.5 million to Cambridge University to create a science library that will house the archives of Nobel Prize-winning physicist Stephen Hawking.

This is the second major gift made by Moore in recent days. He and his wife, Betty, earlier donated $35 million to Conservation International for an environmental hazards task force.

Cambridge officials say the Physical Sciences and Technology Library is planned as the most advanced academic library in Europe. It will house all of Hawking's papers, electronic archive material and a draft of his book, "A Brief History of Time."

The 56-year-old Hawking, is Cambridge's Lucasian Professor of Mathematics. This post was once held by Sir Isaac Newton. The university also houses the archives of Newton and Charles Darwin.

Moore, Intel's chairman emeritus, is the author of Moore's Law, which states that computer memory chip power will roughly double every year or so at little or no added cost.
