Justerini and Brooks’ principal founder, Giacomo Justerini (Giustarini), was a wine merchant from Bologna who was infatuated by an Italian opera singer, Margherita Bellini, whom he followed to London in the mid-eighteenth century (1749). His love is not reciprocated, but Margherita introduces him to Samuel Johnson who will in turn introduce him to his future business partner, his nephew, George Johnson.
