Harvard, the richest university in the United States, said it would seek to raise some $6.5 billion in donations to fund new academic initiatives and bolster its financial aid programme.
The fundraising drive by the Cambridge, Massachusetts, institution is the university's biggest and believed to be the most ambitious ever undertaken by a university, ahead of one concluded last year by Stanford University in California that raised $6.2 billion.
Harvard unveiled its campaign at an event featuring Bill Gates, who spent three years at the school in the 1970s before dropping out to co-found Microsoft. Gates, who was ranked by Forbes magazine this year as the world's second-richest person behind Mexico's Carlos Slim, joked about his decision to leave the university during a talk before alumni and donors.
"You never say that you are 'dropping out' of Harvard. I 'went on leave' from Harvard," he said. "If things hadn't worked out for my company, Microsoft, I could have come back."
Gates did not say whether he intended to donate to the ambitious campaign. A spokesman for the billionaire, whose foundation has made several grants to the university, said later there was nothing to announce.
The university has already raised $2.8 billion from more than 90,000 donors during the pre-launch phase of the campaign, its first major fund-raising drive in more than a decade, it said in a press release.
Harvard's investment portfolio is worth about $30.7 billion, roughly the size of the annual gross domestic product of the Baltic nation of Latvia.
That endowment shrank 0.05% in the fiscal year ended in 2012, after double-digit gains the previous year, according to the most recent figures from the university. "The endowment is meant to last forever... It enables our faculty to do groundbreaking research and supports financial aid for our students," vice-president for Alumni Affairs & Development Tamara Rogers said in a statement. "In order to undertake new activities, we are going to have to raise new funds."
Nearly half of the money raised in the new campaign will support teaching and research, while a quarter will go for financial aid and related programs. The rest will go
