Renormalization in simple quantum mechanical systems is illustrated by diagonalizing the Hamiltonians for the displaced harmonic oscillator and the one-boson Lee model. The diagonalizing transformation for the one-boson Lee model is found by generalizing its dressing transformation. The renormalized fermion masses in the diagonalized Hamiltonian are found to be q numbers.
