Former President Bill Clinton has signed on to be a keynote speaker at the One Young World summit, which comes to Pittsburgh’s David L. Lawrence Convention Center on Oct. 18-22.

Clinton, who works to improve global health, strengthen economies and protect the environment through his William J. Clinton Foundation, will join an expected 1,500 delegates in their 20s. Participants will hear from speakers on subjects including education, sustainable development, global health, social business and youth unemployment. Pittsburgh corporations Alcoa, Bayer, Google, Heinz and PNC are among those sending delegates.

Founded by Kate Robertson and David Jones, heads of (respectively) marketing firm Euro RSCG’s UK office and French advertising agency Havas, the summit aims to “give delegates the kind of media platform and forum afforded ordinarily only to those who lead countries and corporations… tell(ing) the world what the leaders of tomorrow think and feel — and what they demand of the leaders of today.”

Other speakers include online media mogul Arianna Huffington, Mashable CEO Pete Cashmore, Wikipedia founder Jimmy Wales, Pakistani writer Fatima Bhutto, Indian parliamentarian Rahul Gandhi, British singer Joss Stone and Russian model/philanthropist Natalia Vodianova.

Also on hand will be speakers from the 2011 summit in Zurich: anti-apartheid activist Archbishop Desmond Tutu, Irish rocker and anti-poverty activist Bob Geldof; celebrity chef Jamie Oliver; and Mohammad Yunus, the Bangladeshi economist whose work in micro-lending earned him a Nobel Peace Prize.
