Meamish has that podcast something about his personal life?

Information that I have collected some where else:
His ex-wife took some equipments so he could not continue research in Finland so he try to go work for Edison.
His only child died at 1925.

And wikipedia:
"When it finally seemed that Tigerstedt was on the verge of commercial success, he was involved in an ultimately fatal car accident on April 20, 1924, when another car unexpectedly turned in front of the car Tigerstedt was travelling in. There were persistent rumours that a competitor had arranged for the accident, but there was never any proof of this."

This guy deserve the movie.
