Weak gravitational lensing by dark matter is the most direct way to measure
the amount and distribution of dark matter.  Weak lensing has already
yielded measurements of the mass power spectrum Omega_M*sigma_8, and
promises to provide constraints on the equation of state parameter w and its
time evolution w'. I will discuss the brief history of weak lensing by large
scale structure and discuss current weak lensing results.   I will discuss
several planned projects that will utilize weak lensing including the
CFHTLS, LSST, the COSMOS 2-square degree survey, and, finally, SNAP.  I will
outline the current plans for weak lensing with SNAP and present the
constraints on cosmological parameters we hope to set using SNAP.
