Israel Finkelstein is the founding father of the Tel Aviv School, a group of Israeli archeologists who are skeptical about sizable chunks of the Biblical story of early Jerusalem. He is the co-author of The Bible Unearthed: Archaeology's New Vision of Ancient Israel and the Origin of Its Sacred Texts, perhaps the single most important popular book for those who'd like to minimalize the Jewish history in Jerusalem - though I rather suspect most people who cite it have never read it, and most of those who have read it don't understand its context. They find joy in the perceived ambiance, and examine no further.
A demonstration of the degree to which Finkelstein isn't the bogeyman many of his supporters think he is can be found an an interesting article he has just published in The Forward, which appears under a mid-20th century photograph of the area which demonstrates what he's talking about: It's not Silwan, it is an archeological site of unique significance, and even if he, Finkelstein, doubts the stories about David and Solomon, the parts about Isaiah and Hezekiah are certainly true. Furthermore, the scholarship of the archeologists digging there is impeccable (remember that Haaretz suggested otherwise earlier this week).
I recommend reading it.
