  Using FORS2, mounted on Kueyen (UT2 of the VLT), we have obtained the
redshift of the lensing galaxy in the gravitational lens system HE1104-1805. We
measure z=0.729, in good agreement with previous estimates based on the time
delay and the position of the lens on the fundamental plane. It also coincides
with one of the metal line absorption systems that are seen in high resolution
spectra of HE1104-1805.
