P. T. Barnum: The Legend and the Man, by A. H. Saxon (TPB, 1989, 437 pages, $3.50)
" We know him as a circus proprietor and founder of The Greatest Show on Earth", or we know him as the discoverer of General Tom Thumb, the midget, and the impresario of the renowned Swedish Singer Jenny Lind, or perhaps we know him as a man addicted to practical jokes, whose most memorable pronouncement is supposed to have been "there's a sucker born every minute... By delving into much heretofore unpublished material...Saxon reveals that Barnum was, paradoxically, very much a private person and a deeply religious man."
