This research is a contribution to the study of the physical structure and the state of evolution of the binary system ζ Herculis ( ζ Her). This double star has a period of 34.49 years, which is half as short as that of the system of α Centauri. In order to determine with very great precision the fundamental parameters of the atmosphere of the primary component ζ Her A, a new detailed spectroscopic analysis, based on high resolution and high signal/noise spectra, has been carried out for this star. The duplicity of the observed star has been taken into account in as detailed a way as possible. The present analysis attributes to the star a higher effective temperature than that found in previous detailed analyses, and a solar metallicity. The new results are used to rediscuss the age and the masses of the system, with the help of internal structure models.
