  A review on current theories and observations of high-mass star formation is
given. Particularly the influence of magnetic fields and feedback mechanisms,
and of varying initial conditions on theories are discussed. The, in my biased
view, most important observations to put strong constraints on models of
high-mass star formation are pres ented, in particular bearing on the existence
and properties of high-mass starless cores, the role of filaments in the mass
transport to high-mass cores, and the propertie s of disks around high-mass
stars.
