What Happened When Wall Street Trusted a Salad Oil Tycoon?

In 1963, Wall Street lent millions against a New Jersey tank farm on nothing but paperwork. The oil vanished — and the warehouse that certified it every month could never explain how.
This is the Great Salad Oil Scandal: how field warehousing worked, why $136 million in receipts stood behind $6 million of actual liquid, and why the failure wasn't one con man but the design of the system itself.
