Also known as
Karl Ludwig Gerwien can be seen cited as , but this cannot be corroborated.

While his early works are attributed to one P. Gerwien, there is no evidence that P. stands for Paul, but instead is more likely to be an abbreviation of the honorific '''Pr. Lt.''' according to his rank of $2$nd Lieutenant.

Some citations refer to Karl Ludwig Gervien, but it is straightforward to ascertain that this is a mistake.
