    An operator A with superscript as dagger refers to the transpose conjugate (i.e, we take the transpose of the matrix A and replace each element of the matrix by its complex conjugate).

    is the transpose conjugate of a linear operator; once aa is defined as the annihilation operator (presumably because annihilation starts with the letter a), Dirac showed that the corresponding creation operator corresponds to it's transpose conjugate, hence the creation operator is a†a†. Thus the a comes first, and then the ††. I wouldn't assume that Dirac is responsible for the †† notation for transpose conjugate; it is not the only way it is written in mathematical texts, though it is certainly the favorite among physicists today.
