The theory and practice of measuring B-hadron lifetimes, and extracting the Cabibbo-Kobayshi-Maskawa (CKM) matrix element Vca are reviewed. Experiments from CESR, DORIS, PEP, PETRA, LEP, and Fermilab are included to form an up-to-date compilation of the experimental results.The generic lifetime measurement techniques, the just-now-emerging meson-specific vertexing methods, as well as indirect methods for measuring lifetime ratios, are discussed
