  The Lenses Structure and Dynamics (LSD) Survey aims at measuring the luminous
and dark matter distribution of high redshift early-type galaxies by combining
gravitational lens analysis with newly determined velocity dispersion profiles.
Here we describe the first results from the LSD survey, a measurement of the
internal structure of the lens galaxy in MG2016+112 (z=1.004). The relevance of
this measurement to the cosmological model is briefly discussed, in particular
in the context of E/S0 galaxy formation and evolution, the existence and shape
of universal dark matter profiles, and the measurement of the Hubble constant
from gravitational time delay.
