Abstract
Recent numerical Monte Carlo simulations of the hadron spectrum are reviewed. After a general introduction, different ways of calculating the hadron masses in the "quenched approximation" (i.e., neglecting virtual quark loops) are described and the latest results are summarized. The pseudofermion method and the iterative hopping expansion method for the introduction of dynamical quarks is discussed, and the first results for the hadron spectrum including the effect of virtual quark loops are reviewed. A separate section is devoted to the discussion of questions related to scaling with dynamical quarks.
