At the time, Tom Daly was putting together the NFB's now-famous Unit B; Jackson and Colin Low were its first two members.
They were joined by Terence Macartney-Filgate, Robert Verrall, Norman McLaren, Roman Kroitor, Don Owen, Arthur Lipsett, Wolf Koenig and Hugh O'Connor.
[3]Jackson was known as a meticulous filmmaker and, along with Low, as the ‘conscience’ of Unit B; the two men worked together to make sure that no documentary descended into voyeurism.
A bachelor with no relatives, Unit B was Jackson's family—to the point where he paid the school tuition for Kroitor's son for two years.
