Sometime during this period, Pask met George Spencer-Brown who became a lodger at the Pask family's home while working at Stafford Beer and Roger Eddison's operational research consultancy SIGMA (Science in General Management) via strong recommendation from Bertrand Russell. It was here where Spencer-Brown is said to have written his Laws of Form for long hours whilst inebriated in the Pask family's bathtub. According to Vanilla Beer, Stafford's daughter, Pask is purported to have claimed while reminiscing about Spencer-Brown's time at his and his wife's household, that "When [Spencer-Brown] bathed, it wasn't often. He used my gin, to wash in."
