Harry Harrison was born 12th March 1925 in Stamford, Connecticut, where he spent the first two years of his life. His family then moved to Brooklyn, and then to another borough of New York City, Queens, where Harrison grew up and went to school. Hank Dempsey Harry Harrison was born Henry Maxwell Dempsey - his father was also Henry (or Harry or Hank) Dempsey. Henry Dempsey Sr. changed the family name to Harrison soon after his son was born, and so Harry Jr. went through school and the army as Harry Harrison: it was not until he applied for a passport, at the age of thirty, that he discovered the name on his birth certificate was not Harrison. Deciding to carry on being Harrison, he legally changed his name to Harry Max Harrison.
