Can we draw the following hypothesis from the context?

Context:

The Santos-Dumont No.6 was an airship designed and built by the Brazilian pioneer aviator Alberto Santos-Dumont. In 1901 it was used by him to win the Deutsch de la Meurthe prize for a return from Parc Saint Cloud to the Eiffel Tower and back. It is considered by many to be the first truly successful airship.

Hypothesis: Alberto Santos-Dumont won a French prize.
It's impossible to say
