Death Valley wasn't "invented" by any single person. Instead, it was named by a group of European-Americans.
The name "Death Valley" originated in 1849 during the California Gold Rush. A group of pioneers, seeking a shortcut to the gold fields, became trapped in the harsh valley. While only one member of the group perished there, the name stuck as a testament to the valley's unforgiving environment. It's important to note that indigenous peoples inhabited the area long before European-Americans arrived.
Therefore, it's more accurate to say that Death Valley was named rather than invented.
