The dynamic dipole polarizabilities for Li atoms and Be{sup +} ions in the 2 {sup 2}S and 2 {sup 2}P states are calculated using the variational method with a Hylleraas basis. The present polarizabilities represent the definitive values in the nonrelativistic limit. Corrections due to relativistic effects are also estimated. Analytic representations of the polarizabilities for frequency ranges encompassing the n=3 excitations are presented. The recommended polarizabilities for {sup 7}Li and {sup 9}Be{sup +} are 164.11{+-}0.03 a{sub 0}{sup 3} and 24.489{+-}0.004 a{sub 0}{sup 3}, respectively.
