An officer at the Guaranty Trust Company remembered Ida coming to the bank in 1907, at the height of the financial panic, demanding the balance of her account in cash and stuffing all of it, nearly $1 million, into a netted bag. Declaring she was “tired of everything,” she checked into the Herald Square Hotel and disappeared, effectively removing herself from her own life...There's much more about this interesting lady at the Smithsonian source (where there's a citation to a book written about her.)
Next they examined Ida’s 54 trunks, some stored in the basement of the hotel, others in an uptown warehouse. Inside lay bolts of the finest lace from Ireland, Venice and Spain; armfuls of exquisite gowns, necklaces, watches, bracelets, tiaras and other gem-encrusted pieces; several $1,000, $5,000, and $10,000 gold certificates dating back to the 1860s; a gold-headed ebony stick (a Wood family heirloom that had been a gift from President James Monroe), and an 1867 letter from Charles Dickens to Benjamin Wood. Each trunk was taken to the Harriman National Bank, where the contents were placed in vaults. In an old box of stale crackers they discovered a diamond necklace worth $40,000.
