John of Kronstadt
He was born as Ivan Ilyich Sergiyev in 1829. From 1855, he worked as a priest in Saint Andew's cathedral in Kronstadt. Here, he greatly commited himself to charity, especially for those who were remote from the church, and travelled extensively throughout the Russian empire. He was a member of the right extremist Sojuz Russkogo Naroda (Alliance of the Russian people), but did not commit himself politically. He was already greatly venerated at the time he died. He was glorified by the Russian Orthodox Church Outside of Russia in 1964 and by the Russian Orthodox Church in 1990. The second largest monastery of St. Petersburg (by community size) is dedicated to St. John of Kronstadt.
