A closed expression for the dynamic susceptibility of a noninteracting Fermi liquid at finite temperature is presented. The expression for the imaginary part is particularly simple while the real part appears as a sum. The calculation of the sum is discussed and numerical examples displaying the temperature dependence of the susceptibility are given.
