 * Keep He discovered the 9th perfect number in 1883. See List_of_perfect_numbers. The 8th perfect number was discovered by Euler in 1772. Even it was not the largest perfect number known by that time (the 12th perfect number was dicovered by Lucas in 1876), the discovery is still notable. Only two more perfect numbers were discovered after that (10th and 11th) without computers. Alexei Kopylov (talk) 01:28, 15 May 2016 (UTC)
 * Keep. The Russian Wikipedia article has convincing sources for WP:GNG (in two Russian-language print encyclopedias, but sources don't need to be in English). I also found what appears to be a journal article about him, but only by reference (I haven't found the article itself): A. E. Raik. Ural'skii matematik Ivan Mikheevich Pervushin. Istoriko-Matematicheskie Issledovaniya 6 (1953). 535-572. —David Eppstein (talk) 21:39, 15 May 2016 (UTC)
