What was Nikola Tesla’s net worth?

Tesla’s incredible imagination and abilities should have provided him with millions of dollars, but his net worth was only $1000 at the time of his death. People would expect him to be a billionaire due to more than 300 patents and royalty payments for his A.C. patent, equivalent to hundreds of millions of dollars, but none of that happened. These gave him fame and the promise of a fortune. The fame remained, but the fortune faded. He spent all of his fortunes on failed projects. Maybe they aren’t useless, but the money invested in their testing caused Tesla to die bankrupt and alone.
