Wolf Rayet {WR} stars are the last stable evolutionary phase of the most massive O stars. This short-lived phase, in which the products of CNO burning {WN type} or He burning {WC type} are seen as a result of the removal of H-rich outer layers by intense stellar wind, and strong internal mixing via convection and overshoot. The resulting strong, broad emission lines, combined with an optically thick inner wind, make it difficult to determine these stars' intrinsic characteristics, particularly luminosity, mass, and age. 72 have revealed themselves via HST, to be close binary and/or cluster members. The newly imaged clusters allow us to accurately determine the distances, luminosities, and ages of the WR members. The very close binaries put strong constraints on binary formation and evolution scenarios. We propose to triple the size of our Cycle 6 SNAP Galactic WR sample {from 25 to 75}, and image 30 WR stars in the SMC and the LMC {for the first time} to search for companions and clusters.
