I just finished reading "Fortune's Children - The FAll of the House of Vanderbilt" "Commodore" Vanderbilt died in around 1877 leaving $105 million to his heirs, primarily William Vanderbilt. Six years later, around 1903, William had doubled the fortune to $200 million dollars. How can I find out how much $105 million in 1877 would be worth today and how much would $200 million in 1883 be worth today? BTW, "Fortune's Children - The FAll of the House of Vanderbilt" is a fascinating examination of the American "Gilded Age." I read the book because my brother and I visted the Biltmore mansion, in AShevlle, owned by Gearge Vanderbilt, on the way to the Joe Nall event in SC.
