Baron von Gerolt, Prussia's minister to United States, checks out Book of Mormon from Library of Congress. He returns it 16 Feb. 1852.

Brigham Young reports to April 1852 conference that this ambassador requests copies of all LDS publications on behalf of Prussian monarch who "wished to investigate our doctrine."
