Edward Jones is part of the Maxis-made Jones family, which could be downloaded from the official website for The Sims, and is still available from The Sims 1 Depot. He starts as a Mailroom Clerk in the Business track.
He shares his name with another Edward Jones, a character from The Sims 3 Store town Roaring Heights. Notably, they are the only two pre-made, playable characters in the franchise to share the same first and last name without being explicitly intended to be versions of the same character (though this does happen with several NPCs in The Sims 2).
Edward may be interpreted as a nerd partly because of his personality as well as his glasses, clothing and hairstyle.
