Courtney Seligman's and Wolfgang Steinicke's online NGC / IC pages are a cornucopia for those who want to know EVERYTHING about these catalogues, but... I wonder why only Edwin Foster Coddington's name was given to an IC object (IC 2574: Coddington's nebula). He discovered only one object, and thus it is known as Coddington's nebula. There are many more of these discoverers of only one NGC or IC object. Perhaps it's interesting to give their names to these objects too.

Maybe someone of you (dedicated astrophotographers and explorers of all sorts of catalogues of deep sky objects) already created your own catalogue of this sort of discoverers and their "only one" objects. Anyway, I'm about to do it.
