Answer:
"He (Abraham Lincoln) was a natural raconteur."
Explanation:
The use of brackets here is to elucidate the use of pronoun that for whom it is initially used. The usage of double quotes symbolizes the extraction of the sentence from a source which maybe someone's words or quotation from a book and to clarify the central thought of the narrator through the statement, emphasize his message more clearly and loudly. He, which is here used for Abraham Lincoln as portrayed by the speaker through the use of brackets. The second statement has unnecessary and incorrect usage of punctuation marks and thus, grammatically inappropriate.
