During my reseach for Percival’s Planet, I had the great pleasure of being assisted by Antoinette Beiser, Lowell Observatory’s delightful archivist and librarian.  She dug up the hefty cache of letters and telegrams sent to Lowell in the days immediately following the announcement of Planet X’s discovery. While Venetia Burney gets a lot of credit for coming up with the name Pluto, she was by no means the only one to think of it – as the following letters and telegrams show!

Dear Sir;

I have read in the paper the account of the finding of the new planet and being interested I would like to suggest the name of Pluto.  I chose this name because I believe this planet is as important as Neptune or Jupiter and deserves the name of the third brother.

Yours very truly,

Mr. Roger Lowell Putnam,
Dear Sir;

I suggest the name “Pluto” for the new Planet. “Atlas” is inappropriate as are others I have heard. The major planets are all named for the ancient gods. Saturn, the father of the gods, has the most distinctive world and two of his three sons are honored, Jupiter and Neptune, now in all fairness let us give the other, Pluto, his due.

As Pluto was Lord of the dark region of the dead, so this planet so far from the source of light should receive his name. Do not break the beautiful system and catalogue the new world by a name which has no real reason in it and will mean nothing to the future generations. Let us not do something for which we will have to apologize in future.

Respfly
Geo. P. Kebbe
