Chief foreign policy advisor in the George W. Bush (dubya) government.
Her name is supposed to come from the Italian musical direction con dolcezza (literally "with sweetness").
The name has occasionally been written "Condoleeza" (it appears as such once on the whitehouse.gov site itself).
Supposedly, the name was chosen by her mother, a pianist. It is not clear to me how con dolcezza, that is pronounced more or less kon-dull-CHETS-sah turns into Condoleeza. I suspect an unfortunate birth registry mixup. Anyway, a Google search makes me think that she is the only human named "Condoleezza" - although I am sure that some ill advised parents after the elections proceeded to inflict the name on an innocent baby girl.
Someone else will have to node about her foreign policy ideas.
