Pastor Hopp was born in Russia on 14 December 1869 in the colony of Frank and came to the United States at the age of 19. He married on 2 February 1889 to Charlotte Miller. He later married Lena Burkhardt, widow of Henry Traut.
After graduating from the Chicago Theological Seminary, he was appointed minister of a small congregation at Park Ridge, Illinois. In 1903, he came to Portland to serve Ebenezer German Congregational Church, a congregation of 70 members supported as a mission church by the general board of the Congregational denomination. From this group he was instrumental in organizing three additional churches, the Second German Congregational, the Congregational Brethren and the Zion Congregational, of which he became pastor when the structure at NE 9th and Fremont was completed in 1914. He served Zion until 1936. Pastor Hopp died on 12/13 May 1948 in Portland.
