Madeline Blair (born 1905) also known as Adelaide Andrews, Jackie or Blackie was an American prostitute from Bridgeport, Connecticut.[1] She was known for being a stowaway aboard the United States Navy ship USS Arizona and plying her trade while on board the battleship.[2] She is sometimes conflated with Madeleine Blair (note spelling), who was born in St. Louis and later became a brothel madam and activist in Chicago and Canada,[3] and whose autobiography was published in 1919.[4]
