Sadly, not unique. Ray Kroc's widow did the same thing with the McDonald's fortune.
But when Mrs. Kroc went to her final reward, she left more than $1B to Salvation Army.
I wonder how the Heinz trusts are set up for the children of John and Teresa. I recall the oldest son had NO use for JFnK which isn’t unusual in those circumstances in any family. Hopefully, the offspring will be more in tune with John and the Heinz family than with Teresa.
