Harry Truman's middle initial is rather unique because, unlike most middle initials, it doesn't just represent the first letter of his middle name - it is his middle name.
His parents chose the name Harry after his mother's brother, Harrison "Harry" Young (1846–1916).[2] They chose "S" as his middle initial to please both of his grandfathers, Anderson Shipp Truman and Solomon Young. The "S" did not stand for anything, a common practice among the Scots-Irish.
It appears that the period after the "S" is generally either included or omitted based on the author's preference alone. This brings forth some interesting questions:
- Can a letter be considered an "initial", or part of an initialism, if it isn't actually "short" for anything?
- Is there technically a "right" way to treat initials like this, or is the inclusion or omission of the period entirely a matter of preference so long as one is consistent?
- Is there a specific word to describe these sorts of initials?
