Vorontsov-Vel'yaminov (1959) and Arp (1966)

Vorontsov-Vel'yaminov published The Atlas and Catalogue of Interacting Galaxies in 1959. A compilation of interacting galaxies found in the Palomar Sky Survey and the Crimean Station of the Institute, The Atlas... was a record of fragmenting galaxies according to Vorontsov-Vel'yaminov, a theory proposed by Ambartsumyan in 1958.
Inspired by both Zwicky's sketches and faint images of peculiar and distorted galaxies, such as those of Vorontsov Velyaminov, Halton Arp spent four years photographing many such objects with the Palomar 200 inch. He believed that "the peculiarities...represent perturbations, deformations and interactions which should enable us to analyze the nature of real galaxies which we observe and which are too remote to experiment on directly". In 1966, he published his Atlas of Peculiar Galaxies, containing high resolution images of 338 systems .
