H. G. Francis was the pen name of Hans Gerhard Franciskowsky, a German science fiction author. He was part of the Perry Rhodan franchise's main writing team from 1971 to 2004.

Peter Griese (1938 - 1996) was a German science fiction author, best remembered for his contributions to the Perry Rhodan franchise. Having discovered science fiction in his school days, he studied engineering and served as an officer in the military before retiring to become a freelance writer in 1986. He had become a member of the Perry Rhodan writing team six years earlier, and oversaw several different aspects, including the 'Atlan' sub-series and the Report section of the magazine. Griese died of heart failure at the age of 57, while working on his last Perry Rhodan story, 'Flucht durch Bröhnder'.
