A famous mathematician's name was R. H. Bing, his first name and middle name are not initials. Wikipedia lists his name (as above), but shouldn't it be R H Bing, with no periods after the R and H*?
I'm certain other people have similar "oddities" with their names, do they have trouble with "official" agencies?
*Unless his first name is R. and middle name is H.?
Some people have single letter first and or middle names. It's not so rare in India, for example, that I didn't see that multiple times a month.
The issues with government agencies can vary.
