52. Oracle CEO Larry Ellison
Yet another difference between Larry Ellison and God...
In June, Harvard University scraps plans for the Ellison Institute for World Health after Oracle CEO Larry Ellison reneges on a $115 million donation promised to the school 10 months earlier.
Oracle spokesman Bob Wynne says Ellison decided to withdraw his pledge as the result of the resignation of Harvard president Lawrence Summers, but he vows that Ellison will announce plans for a donation to another organization within a few weeks.
Ellison has yet to announce such plans.
