I always assumed that those "celebrity net worth" sites that always had his net worth around $20 million didn't know what they were talking about. I'm sure we'll never know this, but it would be interesting to know when and from what he earned most of his wealth. Although the 70s and 80s were his most fruitful eras, and while I'm sure he was very comfortable all that time, I'm guessing that the majority of his fortune was earned from the 90s on when he truly entered this venerated status.
I wonder if he earned more from major NY and London productions or from licensed regional and amateur productions over the years. What a lovely surprise for the various cultural institutions that were bequeathed funds in his will.
I'm so curious to learn what the mission and scope of the new foundation will be.
