This galaxy was discovered on 28 March 1786 by the German-British astronomer William Herschel with his self-made 18.7 inch f/12.8 reflecting telescope in Slough, England. He listed it under the designation I 137. He classified his discoveries according to purely visual impressions, where I stands for bright nebulae. The description reads: «Very bright, round, very suddenly much brighter in the middle, chevelure 3' diameter.» [464] Dreyer listed the galaxy as NGC 2859 in 1888. [313]
