The co-founder of Microsoft, Paul Allen has declared that he is donating half of his wealth in charity. His present worth is projected to be $13.5 billion. Mr. Allen has been associated with charity for long.

This trend was led by Bill Gates and Warren Buffet, who are campaigning for encouraging their counterparts to donate their wealth for charity.

In an effort to convince more and more billionaires for donating their wealth, a program was organized by the duo last month. It was called The Giving Pledge and many billionaires from the country participated in it.

Billionaires like John and Ann Doerr and Eli and Edythe Broad have also planned to donate a part of their wealth.

Mr. Allen revealed in the Chronicle of Philanthropy in 2003 said that the billionaires should move their best step forward to donate their riches.

Earlier, he had funded a valuable study on tuberculosis.

Mr. Allen has also made a significant contribution to the society by starting an advanced brain-science in his hometown. He established another computer science department at the Washington University.

UW professor of computer science and engineering, Ed Lazowska is of the view that he has made valuable contribution in the field of science and also for the Seattle region.
