Remark 2.3.1.2. In the setting of strict $2$-categories, the Duskin nerve $\operatorname{\mathcal{C}}\mapsto \operatorname{N}^{\operatorname{D}}_{\bullet }(\operatorname{\mathcal{C}})$ was introduced by Street in [MR920944]. The generalization to arbitrary $2$-categories was given by Duskin in [MR1897816].
