In this paper, former students of Bill Sandholm provide summaries of Bill's academic contributions as a unifier of evolutionary game theory and also share their personal memories with Bill as a kind, friendly and dedicated mentor. The paper consists on five essays; first on the unification of EGT with the concept of revision protocols and his charming personality, second on stochastic dynamics, third on potential games, fourth on geometric aspects of Bill's analysis, especially on the projection dynamic, and fifth on applications to cultural evolution.
