New and existing UBVJHK(s), spectroscopic, NOMAD, Hubble Space Telescope, and revised Hipparcos observations are employed to determine properties for delta Cep and its host star cluster. The multi-faceted approach ensured that uncertainties were mitigated (sigma/d similar to 2%). The following fundamental parameters were inferred for delta Cep: E(B - V) = 0.073 +/- 0.018(sigma), log tau = 7.9 +/- 0.1, and d = 272 +/- 3(sigma((x) over bar)) +/- 5(sigma) pc. The cluster exhibits a turnoff near B6 (M-*/M-circle dot similar to 5), and the brightest host cluster members are the supergiants xi Cep (K1.5Ib) and delta Cep. To within the uncertainties, the two stars share common astrometric parameters (pi, mu(alpha), mu(delta), RV similar to -17 km s(-1)) and are tied to bluer members via the evolutionary track implied by the cluster's UBVJHKs color-color and color-magnitude diagrams. The cluster's existence is bolstered by the absence of an early-type sequence in color-magnitude diagrams for comparison fields. NOMAD data provided a means to identify potential cluster members (n similar to 30) and double the existing sample. That number could increase with forthcoming precise proper motions (DASCH) for fainter main-sequence stars associated with classical Cepheids (e. g., delta Cep), which may invariably foster efforts to strengthen the Galactic Cepheid calibration and reduce uncertainties tied to H-0.
