NGC 1275 was one of William Herschel's discoveries; he found it on October 17, 1786. John Herschel included it in the GC from observations of d'Arrest and apparently never observed it himself.
It is the dominant member of the Perseus Cluster of Galaxies and a strong radio source, therefore named Perseus A, and 3C 84 from its entry in the 3rd Cambridge Catalogue of Radio Sources. It is also a strong X-ray source. Its nucleus shows emission lines and is of Seyfert type 1 - this galaxy was in Carl Seyfert's original list of galaxies with peculiar emission lines in their nucleus, now called Seyfert galaxies. Filaments of gaseous material are moving explosively outward at 1500 miles per second.

Supernova 1968A was discovered in NGC 1275 on January 25, 1968 by Lovas 7"E and 24"S of the galaxy's nucleus and reached mag 15.5 (IAUC 2051).
