Bob Jackson was the manager of the English football club Portsmouth from 1947 to 1952. Jackson led Pompey to consecutive First Division titles in the 1948–49 and 1949–50 seasons, the only titles in their history. He departed in the summer of 1952 to take over at ambitious Second Division club Hull City, but could not replicate the success he had at Fratton Park. Jackson died in May 1968. Wikipedia
