Answer:
When Cornelius Vanderbilt (the Commodore) passed away in 1877, he left the majority of his fortune valued at $95,000,000 to his oldest son. In today’s dollars, this fortune would be worth around $2.1 billion. He left smaller amounts to all of his other children. This particular son, who received the majority of his fortune, actually doubled it over the next 10 years creating the largest fortune in the world at the time. Within a few short years, his children (the Commodore’s grandchildren) had spent almost all of it.
So basically he left his wealth to his family when he died.
I hope this helped!! :)
