It is proved that the maximal operator of the Weierstrass and Picard summability means of a tempered distribution is bounded from Hp (Rd ) to Lp (Rd ) for all and, consequently, is of weak type (1,1). As a consequence we obtain that the summability means of a function f (Rd) converge a.e. to f. Similar results are shown for conjugate functions and for Fourier series.
