  We present Hubble Space Telescope images and 2 years of optical photometry of
the quadruple quasar HE0435-1223. The time delays between the intrinsic quasar
variations are 14.4+/-0.8 (A-D), 8.0+/-0.8 (A-B) and 2.1+/-0.8 (A-C) days. We
also observed non-intrinsic variations of ~0.1 mag/yr that we attribute to
microlensing. Instead of the traditional approach of assuming a rotation curve
for the lens galaxy and then deriving the Hubble constant (H_0), we assume
H_0=(72+/-7) km/s/Mpc and derive constraints on the rotation curve. On the
scale over which the lensed images occur (1.2"=5kpc/h=1.5R_e), the lens galaxy
must have a rising rotation curve, and it cannot have a constant mass-to-light
ratio. These results add to the evidence that the structures of early-type
galaxies are heterogeneous.
