From August National Geographic...Georg Wilhelm Stellar's was Vitus Bering's naturalist on the Russian expedition that discovered Alaska in 1741. ... Along with the Stellar's jay, Stellar also "discovered" a slew of other creatures to which he added his name...

Stellar sea lion, Stellar's eider and Steller's sea cow.

=================

Just as an aside...I love how countries can be "discovered" when there are already folks who inhabit the place. They should come up with an other word, don't you think? Anything to suggest?
