or certain nations. Small nations and their achievements are often neglected, while the accomplishments of large nations are at times exaggerated." Slavko Bokshan, a Serbian scientist who worked in the same department as Puluj and Röntgen Honours Ukraine's Ternopil Ivan Pul'uj National Technical University is named after him. A stamp published on the occasion of Puluj's 150th Birth Anniversary in 1995. Streets in Kyiv, Lviv and other Ukrainian cities have the name of Ivan Puluj. On 14 May 2021, asteroid 226858 Ivanpuluj, discovered by astronomers at the Andrushivka Astronomical Observatory in 2004, was by the Working Group Small Body Nomenclature in his memory.
