Beowulf "Bey" Shaeffer is a fictional character from Larry Niven’s Known Space series. Shaeffer is a crashlander, a descendent of Earth explorers who colonized the planet We Made It, which orbits the star Procyon. He is the central figure of several stories which revolve around his dealings with Pierson's Puppeteers and human characters in unusual and potentially dangerous activities, which often test his wits and courage to see them through to completion.
