 In this work, the authors provide a selfcontained discussion of all realvalued quasiperiodic finitegap solutions of the Toda and Kacvan Moerbeke hierarchies of completely integrable evolution equations. The approach utilizes algebrogeometric methods, factorization techniques for finite difference expressions, as well as Miuratype transformations. Detailed spectral theoretic properties of Lax pairs and theta function representations of the solutions are derived. Features:  Simple and unified treatment of the topic.
 Selfcontained development.
 Novel results for the Kacvan Moerbeke hierarchy and its algebrogeometric solutions.
