Abstract: Let U be a bounded open plane set, and let f be a bounded analytic function on U, which is the pointwise limit of a bounded sequence $ \{ {f_n}\} $ of uniformly continuous analytic functions. It is shown that one can find another such sequence $ \{ {f'_n}\} $, converging to f, and bounded by the supremum norm of f. A similar result is proved for approximation by rational functions.
