John Hollar, CEO of the Computer History Museum in Mountain View, Calif., welcomes an audience of hundreds Friday at the end of a weeklong celebration of the 50th anniversary of the integrated circuit. Today, the IC powers everything from the pocket-size iPhone to Google's giant server farms.

Gordon Moore's contributions to research and development, and his co-founding of Fairchild Semiconductor and Intel, led to some of the computer industry's most important computer chip innovations. Here, Moore speaks with reporters before appearing onstage Friday at the Computer History Museum.

Moore (left) and Jay Last were two of the eight men who became known as the "Traitoruous Eight" after leaving Shockley Semiconductor Laboratory to form Fairchild Semiconductor in 1957. Fairchild became "the Google of its day," according to Leslie Berlin, Silicon Valley archivist for Stanford University.

The so-called Traitoruous Eight, seen in an image from Friday's presentation, included Julius Blank, Victor Grinich, Jean Hoerni, Eugene Kleiner, Jay Last, Gordon Moore, Robert Noyce, and Sheldon Roberts. The group got that moniker after leaving Shockley Semiconductor Laboratory to form Fairchild Semiconductor in 1957.

The Computer History Museum has notebooks of Jean Hoerni and Robert Noyce on display as part of its collection.

After Fairchild developed the NPN mesa transistor, which had major reliability problems, Hoerni developed the first planar transistor in March 1959, and then engineered a stable planar manufacturing process.

Jack Kilby's notebooks--on display at the Computer History Museum--contained research notes collected while developing the integrated circuit. In 2000, Kilby was a co-recipient of the Nobel Prize for Physics.
