Haskell

Star Trek
Haskell was a member of the Federation Starfleet in the 24th century and served as the Conn officer aboard the USS Enterprise NCC-1701-D under Captain Jean-Luc Picard. In the year 2365 on Stardate: 42193.6, the crew of the Enterprise encountered a cosmic being that called itself Nagilum. It tried to understand the limited existence of humanity and experimented upon this notion by causing Haskell to have a cerebral hemorrhage, killing him. This was a drastic means for Nagilum to understand the concept of death.
