"Biggest woman in the world"? Not quite. This is yet another case of an e-mail forward that includes real photographs but an inaccurate description of what they depict.
Heather Greene, the woman shown in the photographs above, is indeed a real person, but she's not from Holland, nor is she the tallest woman in the world. Heather lives in Las Vegas, and although she is quite tall and passes the 7-foot mark in heels, she is "only" 6'-5½" in her stocking feet, well short of the record for the world's tallest woman.
The photographs sent around with the message quoted above are actually sample pictures taken from her web site, heatherhaven.com. The pictures are "real" in the sense that they have not been digitally manipulated, but they convey a false impression of Heather's true height because she is paired with people who are shorter than average (the man is 5'7" and the woman 5'1"), and she is posing in some of them while wearing shoes with several-inch heels.
Since 1976, the tallest living woman in the world (as recognized by the Guinness Book of World Records) has been 47-year-old Sandy Allen of Shelbyville, Indiana, who reached a height of 7 feet 7-1/4 inches as a teenager before undergoing pituitary surgery to control her growth.
