Houston attorney Joe Jamail, 88, became a legend among lawyers nearly 30 years ago. Back in 1985, he won a $10.53 billion verdict for Pennzoil Co., which sued Texaco Inc. alleging tortious interference with Pennzoil’s contract to buy Getty Oil stock.

“It’s still the highest jury verdict ever,” Jamail, of the Law Office of Joe Jamail, said of his victory in Pennzoil Co. v. Texaco.
