Noah Brooks (October 25, 1830 – August 16, 1903) was a journalist and editor who worked for newspapers in Sacramento, San Francisco, Newark, and New York, and authored a major biography of Abraham Lincoln based on close personal observation. Born in Castine, Maine, he moved to Dixon, Illinois in 1856, where he became involved in the first Republican campaign for President (John Frémont). During the campaign, he became friends with Lincoln. Brooks moved to Kansas in 1857 as a “free state” settler, but returned to Illinois about a year later, then moved to California in 1859. After the death of his wife in 1862, Brooks moved to Washington, D.C. to cover the Lincoln administration for the Sacramento Daily Union. He was accepted into the Lincoln household as an old friend. Unlike most people, Brooks was able to maintain a close friendship with both the President and Mrs. Lincoln. When Brooks was detailed to cover the 1864 Democratic Convention in Chicago, President Lincoln asked Brooks to also report back in detail by private letter.
