John C. Hamer

John C. Hamer (born 1970) is an American-Canadian historian and mapmaker. His research has focused primarily on the history of the Latter Day Saint movement, authoring several books on the topic. Hamer is a leading expert on various schisms within especially non- far-Western (U.S.) portions of the Latter Day Saint "Restoration" movement. Raised in the Church of Jesus Christ of Latter-day Saints (LDS Church), Hamer left the religion before joining Community of Christ in 2010 and now serves as Pastor of its Toronto Congregation.

Hamer was a contributor to By Common Consent, the Restoration Studies Coordinator at Sunstone Education Foundation, and the Executive Director of the John Whitmer Historical Association.

Biography
Hamer's mother's ancestry goes back seven generations to the early Latter Day Saint church in 1833. His family history is connected to many variations of the (Latter Day Saint) Restoration (including Brighamites, Josephites, Rigdonites, Whitmerites, and Strangites).

Hamer was born in the suburbs of Chicago, and grew up in a suburb of Minneapolis. He was raised LDS — and very active as a Deacons Quorum President, Seminary Class President, Eagle Scout at 13 — but became a "closet doubter" as a teenager, and left organized religion altogether as an adult. Uninterested in Mormonism, at age 26 he read No Man Knows My History, and commented that — ironically — Fawn Brodie rehabilitated Joseph Smith for him.

Hamer received a B.A. degree from Brigham Young University, and a master's from the University of Michigan.

He also has produced maps for university presses and museums, including the University of Michigan Press, Columbia University Press, the Smithsonian Institution Press, the Strategic Air and Space Museum, and the Lewis and Clark National Historic Trail Interpretive Center. In Mormon studies, he has made maps for the LDS Church's Joseph Smith Papers Project, Herald Publishing House, Greg Kofford Books, the Journal of Mormon History, Mormon Historic Studies, the JWHA Journal, and Restoration Studies, among others.

On 6 April 2010, Hamer joined Community of Christ. He presently serves as pastor of its congregation in downtown Toronto, Ontario, Canada, and as a Historian for its Canada East Mission. He is President of the Sionito Group of Charities. Hamer is a founding editor at the group blog Saints Herald. Hamer helped found the Community of Christ ministry Latter-day Seekers as well as the on-line, inclusive pastoral gathering, Beyond the Walls.
