Gerdt Bernhard von Bassewitz-Hohenluckow (4 January 1878 in Allewind, Kingdom of Württemberg – 6 February 1923 in Berlin) was a lieutenant in the Prussian militia, a playwright, and an actor. He had his only great success with Peter and Anneli's Journey to the Moon (Peterchens Mondfahrt), which began as a successful stage play in 1912 in Leipzig and was published as a book in 1915. It became one of the best-loved German children's books and has been a bestseller in Germany to this day. After his success, von Bassewitz became assistant stage director in Cologne. Eventually he moved to Berlin, where he made a living as a freelance writer.
