Meet Johann Petursson, the Viking Giant, who at one point was the tallest man in recorded history.
The Human Marvels has more of Johann's story:
Johann Petursson began touring with the Ringling Bros. and Barnum & Bailey show during their 1948 season. Dressed in his Edwardian top hat and tails he began to command a salary of $200 a week. He also began selling giant-sized rings as souvenirs. While these rings fit his finger, one could also pass a silver dollar through them.
Petursson’s time with Ringling Bros. was brief. He soon joined a sideshow managed by Glen Porter and it was under the management of Porter that Johann would develop his most famous trademark. Porter, aware of Johann’s Icelandic and Nordic roots had his wife craft a costume consisting of Viking regalia and a giant helmet. Johann became known as The Viking Giant and his marketability instantly soared.
