From James C. Schaap
Henry Whipple was one of the first students. Don't be fooled--not the Henry Whipple, the famous Minnesota missionary who, in 1862, pleaded with President Lincoln for the lives of hundreds of Dakota braves and won.
This Henry Whipple was a cute little Navajo six-year-old, who no one on earth had called "Henry Whipple" until he came to the new school at the mission, Rehoboth Mission. In 1903, that Henry Whipple was one of Rehoboth's very first students. He's the little guy down on the left.
But there was another reason too, that one not so noble. Those very first teachers, all of whom spoke with thick Dutch brogues, didn't stand a chance of pronouncing Henry Whipple's Navajo name--whatever it was--so they simply dropped it and gave him a name rich with honor and a whole lot easier to pronounce.
