Measurements of the average b-hadron lifetime using inclusive B {yields} J/{psi}X events, the individual B{sub u} and B{sub d} lifetimes and their ratio using exclusive B {yields} {psi}K events, and the B{sub s} lifetime using semileptonic B{sub s} lifetime using semileptonic B{sub s} {yields} l{nu}D{sub 3}X events are presented. The results were obtained from a 21.3 pb{sup {minus}1} sample of {radical}s = 1.8 TeV {bar p}p collisions collected in 1992--93 at the Fermilab Tevatron collider and required the precise position measurements of the recently installed CDF silicon vertex detector.
