Lieberath was a physical education teacher in Gothenburg when he found a copy of Scouting for Boys by Robert Baden-Powell during a boat trip.
Lieberath sat down and started to read the book and was thus inspired to try Scouting in Sweden.
Thanks to his translation of the book and personal boosting, Scouting ideas spread in Sweden.
Lieberath co-founded the Swedish Guide and Scout Association in the Crown Prince Hotel in Stockholm in 1912.
Lieberath wrote thirty books for young people, such as Klämmiga pojkar (Spirited Boys) (1924).
