Would I need to put (Emerson) for each one of the quotes in this sentence? And is the commas placed correctly?

This is for an reflection essay and I have already mentioned the title of where I got these quotes from before this sentence and I am only talking about only one of Emerson's work.

Such as, “...imitation is suicide...,” “To be great is to be misunderstood,” and “...the great man is he who in the midst of the crowd keeps with perfect sweetness the independence of solitude” (Emerson).

If you put Emerson's name in a short intro to the sentence or paragraph in which you use the quotations, you don't need to put his name after each use.
