John Rundle Cornish (7 October 1837 – 20 April 1918) was an Anglican bishop, the inaugural Bishop of St Germans from 1905 to 1918.
Born on 7 October 1837 he was educated at Sidney Sussex College, Cambridge, where he was 14th Wrangler in 1859.[1] He was a Lecturer then Fellow[2] at the College before studying for ordination. His subsequent appointments included a period as Vicar of Kenwyn,[3] the post of Principal of Truro Training College and Archdeacon of Cornwall[4] before a 15-year stint as a suffragan bishop as the inaugural Bishop of St Germans. He died on 20 April 1918 and a school (the Bishop Cornish C of E VA Primary School) in the locality is named after him.[5] After Cornish's death the bishopric of St Germans remained dormant for 56 years.[6]
