Orvil Lynch Grant, the corrupt younger brother of President Ulysses S. Grant, was rumored to have been a pretty shady guy who was always looking to make a quick buck. As a young man, Orvil ran the family leather shop with his other brother, Samuel, in Galena, IL, before relocating to Chicago.
He also happened to be involved in one of the many scandals that rocked his brother's administration. In 1875, President Grant's Secretary of the Interior Christopher Delano was accused of mismanaging provisions and land in the West as well as taking bribes for land allocation. Delano allegedly gave his own son, John, and the president's brother Orvil positions within the agency, but neither man ever did any work.
Orvil was also connected to his brother's Secretary of War, William Belknap, who took kickbacks on trading posts in the West. As a result, traders had to raise prices just to cover the payments to Belknap and Orvil, which the consumers - many of them soldiers - complained about publicly. When the Senate investigated the bribes, General George Armstrong Custer went on record against Belknap and implicated Orvil as well.
Orvil then went on to work with a lawyer in New York state named J.H. Smith and the two men allegedly swindled a widow out of her money, using the president's name to do so. The relationship between the two men broke down later in their lives, perhaps due to intervention by the First Lady, Julia. Orville reportedly died in an insane asylum at the age of 45, although his wife denied it.
