NMR data from high-T{sub c} superconducting cuprates having widely different T{sub c,max} values and different hole concentrations, p, are shown to implicate a d-wave-like pseudogap. The deduced pseudogap energies agree well with the gap in the charge excitations determined from photoemission measurements, and the gap energies scale with T{sub c,max}. The pseudogap and superconducting gap thus have the same energy scale and for different cuprates have a universal p dependence. {copyright} {ital 1997} {ital The American Physical Society}
