Let (X, , μ) be a σ-finite measure space, p fixed, 1 < p < ∞, T a linear operator of Lp(X,μ), {αi} a sequence of complex numbers. If

exists and is finite a.e. we say the individual weighted ergodic theorem holds for T with the weights {αi}

In this paper we show that if {αi} is a bounded Besicovitch sequence and T is a Dunford-Schwartz operator (i.e.: ||T||1≤1, ||T||≤1) then the individual weighted ergodic theorem holds for T with the weights {αi}.
