A prominent Texas lawyer who made his name and his fortune in high-profile lawsuits against tobacco companies and diet-drug and breast-implant makers has left the bulk of his estate to charity, according to The Houston Chronicle.

A will filed Friday in probate court showed that John O’Quinn, who died at age 68 after a car crash the previous day, directed most of his assets to his charitable foundation.

Started in 1986, the John M. O’Quinn Foundation had $3.9-million in assets in 2008 and in recent years had given millions to support health and mental-health organizations, higher education, and other causes. The newspaper noted that Mr. O’Quinn’s assets include a $5-million home.
