Retiring Microsoft Corp. Chairman Bill Gates will visit Carnegie Mellon University Feb. 21 in the final stop of his "farewell tour" before stepping down from the company.

Mr. Gates will meet with faculty members and address the Carnegie Mellon community that afternoon in Rangos Auditorium in the University Center. The visit is not open to the public, and only those with Carnegie Mellon IDs will be admitted to his speech, entitled "Bill Gates Unplugged: On Software, Innovation, Entrepreneurship, and Giving Back."

Carnegie Mellon has a close relationship with Microsoft. More than 300 alumni work for the company, including two vice presidents. The company's research branch helped fund the Center for Computational Thinking at the university, and one of two new computer science buildings at the school will be named the Gates Center, financed partly with a $20 million gift from the Bill and Melinda Gates Foundation.
