Abstract: We present a new observational project to study the prototypical semidetached binary system, Algol. Over 80 high-resolution and high-S/N spectra were secured in 2006 and 2007 with FIES at the Nordic Optical Telescope on La Palma. All three components were successfully detected by the method of spectral disentangling, which yields the individual spectra of the three stars and also high-accuracy spectroscopic elements for both the inner and outer orbits. Our next step is to study the chemical composition of the components in detail, in particular the close eclipsing system which is in the stage after mass reversal.
