Abstract. We present the computation of the elementary solutions of the Dirac equation, in the sense of Hadamard, and the subsequent evaluation of the vacuum polarization, worked out by Țițeica, in four papers, published in the early forties of the previous century. Even if the quantum electrodynamics has chosen, about ten years later, a different evolution, Țițeica’s papers, which produced results confirmed by subsequent researches, remain valuable and interesting, from a historical perspective.
