🤓 Fun Facts
Henry Charles ‘Inky’ Stephens served as MP for Finchley while running the ink firm—hence the nickname that stuck to both man and brand.
Stephens bequeathed Avenue House and its grounds for public benefit in 1918—an early example of a North London industrialist endowing civic green space.
Stephens’s blue-black formula was prized by clerks because it wrote blue and dried nearly black—the iron-gall chemistry literally darkened as it oxidised.
