According to a cursory web search, white flour was commonly used for bread in industrialized nations since the late 1800s, perhaps partially because white flour did not spoil as easily as whole wheat flour, but perhaps also because white flour was considered a high status food once available only to the rich. Enriching white flour was specified in the 1940s by the US military to ensure that soldiers in World War II were better nourished than they were as new conscripts or recruits who were likely to have had vitamin deficiencies eating white bread and little else living in depression poverty.
Of course, enriching white flour does not replace all of the nutrients lost with the bran and germ, and obviously does not replace any of the fiber. Although just to confuse things even more, there is something called "white whole wheat flour" which is whole wheat flour made from a variety of wheat whose bran is closer to white rather than red or brown like the usual variety of wheat. Then again, if you want to try to get a resistant person to eat whole wheat bread instead of white bread, making some "white bread" with white whole wheat flour may be worth a try.
