When Aasen was 10 years old, he and his mother moved from Ridgeway, Iowa (where his uncle Sam/Sevre lived with his wife Cornelia), to Sheyenne, North Dakota, with his two younger siblings.

According to some sources, Aasen was around 2.74 m or 8 feet, 11½ inches (which, if true, would make him even taller than Robert Wadlow, the tallest verified person in history).

A Norwegian man named Bent Lønrusten spent 13 years of his life trying to find out Aasen's true height.

Bent was a guest on a Norwegian podcast called "Rekommandert", talking about Aasen's history and how he found out his true height.

[1] Later, he acted in several other films like Bengal Tiger, Charlie Chan at the Circus, Growing Pains, Should Married Men Go Home?, Legionnaires in Paris, Two Flaming Youths, The Sting of Stings, Long Fliv the King and the Tod Browning film Freaks, in a small uncredited cameo appearance.

Aasen's cremated soft parts were given a Masonic funeral at Forest Lawn Cemetery in Glendale, California.
