The formation of massive stars along the W5 ionization frontFar-infrared, near-infrared, millimeter-wave, and optical data are presented for two of the large molecular clouds which border the W5 (IC 1848) giant H II region. These data are combined to identify three B0-B2 zero-age main-sequence stars which are forming in these clouds and to study the density distribution and kinematic structure of their surrounding molecular gas. This investigation into the environment in which massive stars have formed in these clouds, when considered alongside similar studies of the W5A/S201 molecular cloud, leads to the conclusion that the expanding W5 H II region has played an important role in initiating the formation of these massive stars.
