The woman on the left is the actress Maureen O’Sullivan, who played Jane in several Tarzan movies, and went on to a long career in the industry. The taller woman is a lesser-known actress named Ann Morriss, who was about 5’9″. The actresses were working on a 1938 film called Spring Madness.
Wadlow was about nine feel tall when he died at 22. He wore a size 37 shoe (some sources say 39), and weighed 481 pounds at his highest point. He is the tallest known human in history, and was still growing when he died.
Guinness lists him at 8’11”, and is one of only five or six people on record who exceeded 8 foot 6; none of them lived to see their 40th birthday. The Bible’s famous “giant” Goliath, by the way, is usually described as measuring “four cubits and a span,” which is only around 6’9″ if you take the generally accepted definition of what a cubit is. LeBron could have stared Goliath in the face. The tallest living human, some guy in Turkey (sorry, Turkiye), is a hair under 8’3″.
