Henry Bill (May 18, 1824 - August 14, 1891) was an American book publisher. Born in Groton (now Ledyard), Connecticut to Lucy and Burdon Bill, Henry attended the academy in Plainfield as a boy. After graduation, Bill taught in Groton and Plainfield until, at the age of twenty, a relative, James A. Bill, offered him a job in Philadelphia workin for the book publishing business he owned. Bill spend the next three years learning the publishing business and selling books door to door in the western states. Then, in 1847, Bill moved to Norwich where he opened his own publishing firm. The elder of the Harper Brothers of New York recognized his skill and gave Bill support and an unlimited line of credit. Over the following twenty-five years, Bill's publishing company produced hundreds of thousands of books and by 1865 was among the sixty wealthiest men in Norwich. When faced with failing health and the prospect of retirement, Bill converted his business into a joint-stock company, creating the Henry Bill Publishing Company, which continued to flourish for years. Bill was also involved in politics, serving as a member of the State Senate in 1853. As a member of the Democratic Party, when the party split in 1856, he chose the anti-slavery group, and became an active member of the fledgling Republican Party. Bill was also very successful with his real estate investments and was also one of the founders of Chelsea Savings Bank, serving as the bank's vice president from 1858 until 1882. Bill married Julia O. Chapman on February 10, 1847, with whom he had seven children.
