Question: When was the author of Public Enemy Number Two born?
Context: Samuel Green (1796 – April 25, 1822) was an American serial killer and robber.  He has been called America's first "Public enemy Number One" The War on Drugs is an American term usually applied to the United States government's campaign of prohibition of drugs, military aid, and military intervention, with the stated aim being to reduce the illegal drug trade.  This initiative includes a set of drug policies that are intended to discourage the production, distribution, and consumption of psychoactive drugs that the participating governments and the UN have made illegal.  The term was popularized by the media shortly after a press conference given on June 18, 1971, by United States President Richard Nixon—the day after publication of a special message from President Nixon to the Congress on Drug Abuse Prevention and Control—during which he declared drug abuse "public enemy number one".  That message to the Congress included text about devoting more federal resources to the "prevention of new addicts, and the rehabilitation of those who are addicted", but that part did not receive the same public attention as the term "war on drugs".  However, two years prior to this, Nixon had formally declared a "war on drugs" that would be directed toward eradication, interdiction, and incarceration.  Today, the Drug Policy Alliance, which advocates for an end to the War on Drugs, estimates that the United States spends $51 billion annually on these initiatives. Gerald Chapman (August, 1887 – April 6, 1926), known as "The Count of Gramercy Park","The Gentleman Bandit" and "Gentleman Gerald", was an American criminal who helped lead an early Prohibition-era gang from 1919 until the mid-1920s.  Chapman was the first criminal to be dubbed "Public Enemy Number One" by the press. Lester Joseph Gillis (December 6, 1908 – November 27, 1934), known by the alias George Nelson, better known as Baby Face Nelson, was an American bank robber in the 1930s.  Gillis was given the nickname Baby Face due to his youthful appearance and small stature, although few dared call him "Baby Face" to his face.  Criminal associates instead called him "Jimmy".  Nelson entered into a partnership with John Dillinger, helping him escape from prison during the famed Crown Point, Indiana Jail escape, and was later labeled along with the remaining gang members as public enemy number one. Ralph "Bottles" Capone, Sr., (January 12, 1894 – November 22, 1974) was a Chicago mobster and an older brother of Al Capone and Frank Capone.  Ralph Capone got the nickname "Bottles" not from involvement in the Capone bootlegging empire, but from his running the legitimate non-alcoholic beverage and bottling operations in Chicago.  Further family lore suggests that the nickname was specifically tied to his lobbying the Illinois Legislature to put into law that milk bottling companies had to stamp the date that the milk was bottled on the bottle.  He was most famous for being named by the Chicago Crime Commission "Public Enemy Number Three" when his brother Al was "Public Enemy Number One".
