It’s a lofty dream, particularly because he is no longer around to speak at fund-raisers. It’s almost as inconceivable as the dream he had when he was an African cattle-herder aspiring to play in the N.B.A.  and this too can be a slam-dunk, posthumously, if his fans help out.

If each admirer chipped in the cost of a ticket to just one game, if each of his former teams agreed to match donations, if a few current and former N.B.A. stars agreed to stand in for Bol at fund-raisers, why then schools would sprout all across Sudan.

The first of Bol’s 41 schools is now approaching completion in his childhood village, said Tom Prichard, executive director of Sudan Sunrise, the charity that Bol used to build his schools. Forty to go.

Bol grew up herding cattle. Twice he ran away in hopes of attending school, but he never got much formal education. He moved to the United States and played in the N.B.A. from 1985 to 1995, setting a rookie record for blocking shots. He was a curiosity, the tallest player in the league when he started.

As Bol began playing before large crowds in America, his homeland exploded in violence. Northern Sudan waged a savage war against the South, costing roughly two million lives. American officials and news organizations mostly looked the other way, but Bol worked passionately to ease the suffering.
