A woman who saved 3,000 years of history.
She saved Egyptian tourism; the Aswan High Dam should never have been built, period, it has been a disaster all the way around, and the electrical needs (even in Egypt) are not anywhere near 100% served by the dam, which was the original claim.
The Russians managed to make an interesting discovery while drilling into the basement to check the strata, making sure it could hold the mass of the dam with all that water behind it, found that the Nile had cut out a Grand Canyon-like gulch millions of years ago, when the Med had been isolated from the Atlantic, and water levels had dropped.
