Silicon Valley billionaire Tom Siebel, founder of CRM vendor Siebel Systems (sold to Oracle for $5.8 billion back in 2005), was reportedly attacked and injured by an elephant in Tanzania about a month ago.

The incident is vaguely reminiscent of TechCrunch editor Sarah Lacy’s recent baboon attack in Rwanda, although in Siebel’s case the consequences were a bit more severe than a psychological trauma.

The 56-year-old tech mogul told Mercury News in an interview that he and his guide was attacked by a charging elephant in the Serengeti, breaking several ribs, goring him in the left leg and crushing the right.

Fortunately, unlike Larry Ellison a couple of years ago when he set his sight on the man’s company, the elephant soon lost interest in Siebel and simply walked away from the scene.

The billionaire (estimated worth: $US 1.9 billion as of 2008) had to wait three hours before the radioed medical assistance team showed up and gave him treatment, but is now recovering from his injuries in his Woodside home and expects to make a full recovery after reconstructive surgery and physical therapy. Siebel told the Mercury News Wednesday that he doesn’t know what became of the elephant that attacked him. He added that authorities in Tanzania searched for it, but as far as he knows it was never found.

Not able to come up with a good joke using the phrasing ‘elephant in the room’, I’m just going to conclude by saying we’re all glad Siebel is ok, and we hope the same is true for the animal.
