She's not Einstein, and she's not well known outside of computer scientis. Seems to line up perfectly with ok_craig's comment.

Of course she was brilliant, and influential, but putting her in the same list as Newton or Einstein feels like intellectual hipsterdom.

She's also not well-known inside computer science. I certainly don't know her. Wikipedia isn't a reliable source, so I am not sure what she has done. It appears that she was part of a team that might have developed one of the early loaders/linkers.
