Henry L. Turner (August 26, 1845 - July 12, 1915) was an American businessman and military officer. Born in Oberlin, Ohio, before the age of 20 Turner had graduated from Oberlin College with honors and had served as an officer in two regiments during the American Civil War (1861 - 1865). First, he served as a lieutenant in the 150th Regiment, Ohio Volunteers, and then as Lieutenant and Adjutant for the 1st Regiment United States Colored troops. He fought in battles at Fort Stevens, the siege of Richmond, the second battle of Fair Oaks, the attack on Fort Fisher, and the capture of General Joseph E. Johnston's Army. After the war, he moved to Chicago, Illinois, where he worked with the 'Advance' newspaper. At some point after that he moved to Philadelphia and worked for Jay Cook and Company, the great banking house. He worked for that firm until it failed in 1873. At this point he returned to Chicago and began working for the 'Advocate' again. He bought the paper and managed it for two years before selling it. Turner moved into the world of real estate in 1874 when he founded the firm Turner and Marsh with his brother-in-law. Marsh (the brother-in-law) soon left the firm in favor of a job in Europe, and Turner began a partnership with William A. Bond, which lasted until 1892 when Turner retired from the business. Upon his retirement, Turner opened a banking investment business, which existed until at least 1900. In 1898, when the Spanish-American War was declared, Turner reentered the military as the commanding officer of the 1st Illinois National Guard, which was soon federalized. They were sent to Santiago, Cuba, and participated in the battle that captured that city. He had been in ill health since suffering from sunstroke during the Spanish-American War.
