[1] Jack was born on December 29, 1906, in Saint Lucia, and spent his early years in British Guiana before emigrating to the United States.

The young Hulan worked as a janitor at a paper box factory, eventually rising to become a vice president of the firm.

This caused a major controversy, and Emile Wagner, one of the founders of the New Orleans White Citizens Council, obtained material from the House Unamerican Activities Committee which suggested that Jack was a former member of subversive organizations.

Jack denied the charges, accusing the White Citizens Council of a "rearguard action to disobey the decision handed-down by the Supreme Court on desegregation in schools."

[5][7] On January 16, 1961, Jack was sentenced to a suspended one-year term in prison, which had the effect of automatically removing him from the office of Borough President.
